`
`PROTECTING YOUR INVENTION OUTSIDE THE UNITED STATES
`
`Since the rights granted by a U.S. patent extend only throughout the territory of the United States and have no
`effect in a foreign country, an inventor who wishes patent protection in another country must apply for a patent
`in a specific country or in regional patent offices. Applicants may wish to consider the filing of an international
`application under the Patent Cooperation Treaty (PCT). An international (PCT) application generally has the same
`effect as a regular national patent application in each PCT-member country. The PCT process simplifies the filing
`page 1 of 3
`
`Page 1 of 62
`
`

`

`of patent applications on the same invention in member countries, but does not result in a grant of "an international
`patent" and does not eliminate the need of applicants to file additional documents and fees in countries where patent
`protection is desired.
`
`Almost every country has its own patent law, and a person desiring a patent in a particular country must make an
`application for patent in that country in accordance with its particular laws. Since the laws of many countries differ
`in various respects from the patent law of the United States, applicants are advised to seek guidance from specific
`foreign countries to ensure that patent rights are not lost prematurely.
`
`Applicants also are advised that in the case of inventions made in the United States, the Director of the US PTO must
`issue a license before applicants can apply for a patent in a foreign country. The filing of a U.S. patent application
`serves as a request for a foreign filing license. The application's filing receipt contains further information and
`guidance as to the status of applicant's license for foreign filing.
`
`Applicants may wish to consult the USPTO booklet, "General Information Concerning Patents" (specifically, the
`section entitled "Treaties and Foreign Patents") for more information on timeframes and deadlines for filing foreign
`patent applications. The guide is available either by contacting the USPTO Contact Center at 800-786-9199, or it
`can be viewed on the USPTO website at http://www.uspto.gov/web/offices/pac/doc/general/index.html.
`
`For information on preventing theft of your intellectual property (patents, trademarks and copyrights), you may wish
`to consult the U.S. Government website, http://www.stopfakes.gov. Part of a Department of Commerce initiative,
`this website includes self-help "toolkits" giving innovators guidance on how to protect intellectual property in specific
`countries such as China, Korea and Mexico. For questions regarding patent enforcement issues, applicants may
`call the U.S. Government hotline at 1-866-999-HAL T (1-866-999-4158).
`
`LICENSE FOR FOREIGN FILING UNDER
`
`Title 35, United States Code, Section 184
`
`Title 37, Code of Federal Regulations, 5.11 & 5.15
`
`GRANTED
`
`The applicant has been granted a license under 35 U.S.C. 184, if the phrase "IF REQUIRED, FOREIGN FILING
`LICENSE GRANTED" followed by a date appears on this form. Such licenses are issued in all applications where
`the conditions for issuance of a license have been met, regardless of whether or not a license may be required as
`set forth in 37 CFR 5.15. The scope and limitations of this license are set forth in 37 CFR 5.15(a) unless an earlier
`license has been issued under 37 CFR 5.15(b). The license is subject to revocation upon written notification. The
`date indicated is the effective date of the license, unless an earlier license of similar scope has been granted under
`37 CFR 5.13 or 5.14.
`
`This license is to be retained by the licensee and may be used at any time on or after the effective date thereof unless
`it is revoked. This license is automatically transferred to any related applications(s) filed under 37 CFR 1.53(d). This
`license is not retroactive.
`
`The grant of a license does not in any way lessen the responsibility of a licensee for the security of the subject matter
`as imposed by any Government contract or the provisions of existing laws relating to espionage and the national
`security or the export of technical data. Licensees should apprise themselves of current regulations especially with

`
`FIELD
`
`[0001]
`
`The present invention relates to telemetered subcutaneous sensor devices and,
`
`more particularly, to devices for wireless communication between an implantable subcutaneous
`
`sensor set at a selected insertion site within the body of a user and at least one of a plurality of
`
`remotely located therapy-related devices.
`
`BACKGROUND
`
`[0002]
`
`Diabetes mellitus is the most common of endocrine disorders, and is characterized
`
`by inadequate insulin action. Diabetes mellitus has two principal variants, known as Type 1
`
`diabetes and Type 2 diabetes. The latter is also referred to as DM/II ( diabetes mellitus type 2),
`
`adult-onset diabetes, maturity-onset diabetes, or NIDDM (non-insulin dependent diabetes
`
`mellitus).
`
`[0003]
`
`Over the years, body characteristics have been determined by obtaining a sample
`
`of bodily fluid. For example, diabetics often test for blood glucose levels. Traditional blood
`
`glucose determinations have utilized a finger prick method using a lancet to withdraw a small
`
`blood sample. These systems are designed to provide data at discrete points but do not provide
`
`continuous data to show variations in the characteristic between testing times. These discrete
`
`measurements are capable of informing a patient the state of his blood glucose values at a point
`
`in time. Thus, the patient has enough information to administer "correction" amounts of insulin
`
`to reduce his current blood glucose reading. However, these discrete readings are not able to
`
`provide enough information for any type of automatic or semi-automatic system of administering
`
`insulin based on blood glucose values.
`
`[0004]
`
`Recently, a variety of implantable electrochemical sensors have been developed
`
`for detecting and/or quantifying specific agents or compositions in a patient's blood or interstitial
`
`fluid. For instance, glucose sensors are being developed for use in obtaining an indication of
`
`blood glucose levels in a diabetic patient. These glucose sensors connected (wired or wirelessly)
`
`1
`
`Page 7 of 62
`
`

`

`Attorney Docket No.
`2164-3003Pl
`
`to a blood glucose monitor can provide continuous glucose readings over a period of time, such
`
`as 3 to 5 days. Such readings are useful in monitoring and/or adjusting a treatment regimen
`
`which typically includes the regular administration of insulin to the patient.
`
`[0005]
`
`Thus, blood glucose readings improve medical therapies with semi-automated
`
`medication infusion pumps of the external type, as generally described in U.S. Patent Nos.
`
`4,562,751; 4,678,408; and 4,685,903; or automated implantable medication infusion pumps, as
`
`generally described in U.S. Patent No. 4,573,994, which are herein incorporated by reference.
`
`Typical thin film sensors are described in commonly assigned U.S. Patent Nos. 5,390,671;
`
`5,391,250; 5,482,473; and 5,586,553 which are incorporated by reference herein. See also U.S.
`
`Patent No. 5,299,571. In addition, characteristic glucose monitors used to provide continuous
`
`glucose data are described in commonly assigned U.S. Patent Application No. 11/322,568
`
`entitled "Telemetered Characteristic Monitor System and Method of Using the Same" filed on
`
`December 30, 2005, which is herein incorporated by reference in its entirety. In addition,
`
`infusion pumps receiving sensor data are described in commonly assigned U.S. Patent
`
`Application No. 10/867,529 entitled "System for Providing Blood Glucose Measurements to an
`
`Infusion Device" filed on October 14, 2004, which is herein incorporated by reference in its
`
`entirety.
`
`[0006]
`
`However, drawbacks associated with a prior glucose sensor system are that a
`
`sensor transmitter is only capable of one-way communication and has limited processing power.
`
`Hence, the sensor transmitter can transmit raw sensor data but is unable to receive therapy(cid:173)
`
`related information from a remote therapy-related device. Moreover, the sensor transmitter is
`
`unable to calculate sensor blood glucose values. Accordingly, in the prior glucose sensor
`
`system, it is necessary to couple the sensor transmitter to a remote data receiving device, such as
`
`a characteristic monitor, to determine actual glucose sensor readings. Moreover, when data is
`
`lost because of a failed transmission, the transmitter does not know to re-transmit because it
`
`cannot be informed of the lost data. Therefore, what is needed is a sensor transceiver for use
`
`with a blood glucose sensor that is capable of transmitting and receiving therapy-related data and
`
`independently calculating sensor blood glucose values.

`
`SUMMARY
`
`[0007]
`
`The present invention relates to a telemetered characteristic sensor transceiver for
`
`exchanging data with at least one remote device. The transceiver comprising a housing, a sensor
`
`connector coupling the housing to a sensor located on a body of a user for producing a signal
`
`indicative of a user characteristic, a processor formed within the housing and coupled to the
`
`sensor connector for processing the signal received from the sensor, a transmitter coupled to the
`
`processor for transmitting data to at least one remote device, a receiver coupled to the processor
`
`for receiving data from the at least one remote device, and a memory coupled to the processor
`
`for storing data. Preferably, the processor performs calculations using at least one of the signal
`
`received from the sensor, the data received from the at least one remote device and the data
`
`stored in the memory, and stores the calculations in the memory or transmits the calculations to
`
`the at least one remote device through the transmitter.
`
`[0008]
`
`In accordance with an embodiment of the present invention, the transceiver
`
`exchanges data with a plurality of remote devices in a network structure. In one aspect, the
`
`transceiver exchanges data with the at least one remote device in a synchronous manner.
`
`[0009]
`
`In accordance with another embodiment, the transceiver wakes up from a sleep
`
`mode prior to exchanging data with the at least one remote device, wherein the at least one
`
`remote device wakes up the transceiver. As such, the transceiver further comprises an ultrasonic
`
`sensor for receiving an ultrasonic signal from the at least one remote device when the at least one
`
`remote device transmits the ultrasonic signal to the transceiver to wake up the transceiver.
`
`Alternatively, the transceiver periodically wakes up independent of the at least one remote
`
`device.
`
`[0010]
`
`In another aspect of the invention, the transceiver exchanges data with the at least
`
`one remote device in an asynchronous manner. Preferably, the data exchanged in the
`
`asynchronous manner comprises at least one of a blood glucose value and a request for glucose
`
`history data.
`
`[0011]
`
`In accordance with an embodiment of the present invention, the data exchanged
`
`between the transceiver and the at least one remote device comprises at least one of device
`
`configuration data, communication link configuration data, adaptive communication

`
`configuration data, glucose history data, and calibration data. Preferably, the device
`
`configuration data comprises at least one of a device identification, user information, and time
`
`information. Preferably, the communication link configuration data comprises at least one of a
`
`communication rate, frequency information, and frequency hopping configuration information.
`
`Preferably, the glucose history data is exchanged according to a time interval. Preferably, the
`
`calibration data comprises at least one of sensor initialization sequence and configuration
`
`information, and dynamic sensor initialization parameters.
`
`[0012]
`
`In accordance with another embodiment of the present invention, the processor
`
`calculates sensor glucose values using at least one of the signal received from the sensor, the
`
`data received from the at least one remote device and the data stored in the memory. Preferably,
`
`a rate of exchanging data between the transceiver and the at least one remote device is
`
`dynamically changed depending on a characteristic of the calculated sensor glucose values.
`
`Preferably, a glucose calculation algorithm for calculating the sensor glucose values is stored in
`
`the memory. Preferably, the processor stores the calculated sensor glucose values in the memory
`
`or transmits the calculated sensor glucose values to the at least one remote device through the
`
`transmitter. Preferably, the calculated sensor glucose values are secured via an encryption
`
`scheme before transmission to the at least one remote device.
`
`[0013]
`
`In accordance with another embodiment of the present invention, the receiver
`
`receives calibration data from the at least one remote device and the processor stores the
`
`received calibration data in the memory. Preferably, the processor performs a calibration using
`
`at least one of the calibration data stored in the memory, the signal received from the sensor and
`
`the calculated glucose sensor values. Preferably, a calibration algorithm for performing the
`
`calibration is stored in the memory.
`
`[0014]
`
`In one aspect of the invention, transceiver comprises a display for displaying
`
`information processed by the processor. In another aspect, the transceiver comprises means for
`
`notifying the user that the at least one remote device is beyond a certain distance from the
`
`transceiver.
`
`[0015]
`
`In a further aspect of the invention, a power for exchanging data between the
`
`transceiver and the at least one remote device is dynamically changed depending on a strength of
`
`a detected signal between the transceiver and the at least one remote device.

`As shown in the drawings for purposes of illustration, the invention is embodied
`
`in a telemetered characteristic sensor transceiver coupled to a sensor set, that may be implanted
`
`in and/or through subcutaneous, dermal, sub-dermal, inter-peritoneal or peritoneal tissue, that not
`
`only transmits data from the sensor set to a remote therapy-related device, such as a
`
`characteristic monitor for determining body characteristics, but may also receive data from the
`
`remote device. Although the telemetered characteristic sensor transceiver of the present
`
`invention is described below with regard to a characteristic monitor in particular, the transceiver
`
`need not be coupled to such a device alone. The present invention contemplates the transceiver
`
`operating with other remote electronic devices, such as infusion pumps, monitors, personal
`
`computers and hospital system devices, for example. Moreover, the transceiver may be linked to
`
`a single electronic device or numerous devices in a network structure.
`
`[0032]
`
`In preferred embodiments of the present invention, the sensor set and monitor are
`
`for determining glucose levels in the blood and/or body fluids of the user without the use of, or
`
`necessity of, a wire or cable connection between the transceiver and the monitor. However, it
`
`will be recognized that further embodiments of the invention may be used to determine the levels
`
`of other agents, characteristics or compositions, such as hormones, cholesterol, medication
`
`concentrations, pH, oxygen saturation, viral loads ( e.g., HIV), or the like.
`
`[0033]
`
`In other embodiments, the sensor set may also include the capability to be
`
`programmed or calibrated using data received and stored by the telemetered characteristic sensor
`
`transceiver, or may be calibrated at the monitor (or receiver). The telemetered characteristic
`
`sensor system is primarily adapted for use in subcutaneous human tissue. However, still further
`
`embodiments may be placed in other types of tissue, such as muscle, lymph, organ tissue, veins,
`
`arteries or the like, and used in animal tissue. Embodiments may provide sensor values to and/or
`
`receive therapy-related information from a remote device on an intermittent or continuous basis.

`
`telemetered characteristic sensor transceiver device embodying the novel features of the
`
`invention. FIG. 2 is an enlarged longitudinal vertical section taken generally on the line 2--2 of

`
`with a preferred embodiment of the present invention includes a percutaneous sensor set 10, a
`
`telemetered characteristic sensor transceiver device 100 and a characteristic monitor 200.
`
`Preferably, the telemetered characteristic sensor system 1 provides for better treatment and
`
`glycemic control in an outpatient or home-use environment. For example, the sensor system 1
`
`can provide indications of glucose levels, hypoglycemia/hyperglycemia alerts and outpatient
`
`diagnostics. It is also useful as an evaluation tool under a physician's supervision.
`
`[0035]
`
`The percutaneous sensor set 10 utilizes an electrode-type sensor, as described in
`
`more detail below. However, in alternative embodiments, the system may use other types of
`
`sensors, such as chemical based, optical based or the like. In further alternative embodiments,
`
`the sensors may be of a type that is used on the external surface of the skin or placed below the
`
`skin layer of the user. Preferred embodiments of a surface mounted sensor would utilize
`
`interstitial fluid harvested from underneath the skin.
`
`[0036]
`
`The telemetered characteristic sensor transceiver 100 generally includes the
`
`capability to transmit and receive data. Preferably, the telemetered characteristic sensor
`
`transceiver 100 facilitates two-way communication between the sensor set 10 and the
`
`characteristic monitor 200. The sensor transceiver 100 also includes the ability to determine the
`
`characteristic reading using raw data received from the sensor set 10. The characteristic monitor
`
`200 can also determine the characteristic reading using data transmitted from the transceiver 100.
`
`[0037]
`
`In alternative embodiments, the characteristic monitor 200 may be replaced with a
`
`data receiver, storage and/or transmitting device for later processing of the transmitted data or
`
`programming of the telemetered characteristic monitor transceiver 100. In further embodiments,
`
`the telemetered characteristic sensor transceiver 100 can maintain multiple two-way
`
`communication links with other devices, such as infusion pumps, monitors, personal computers
`
`and hospital system devices, for example.
`
`[0038]
`
`In addition, referring to FIG. 9, a relay or repeater 4 may be used with the
`
`telemetered characteristic sensor transmitter 100 and the characteristic monitor 200 to increase
`
`the distance that the telemetered characteristic sensor transceiver 100 can be used with the
`
`characteristic monitor 200. For example, the relay 4 could be used to provide information to
`
`parents of children using the telemetered characteristic sensor transceiver 100 and the sensor set
`
`10 from a distance. The information could be used when children are in another room during
`
`sleep or doing activities in a location remote from the parents. In further embodiments, the relay
`

`
`4 can include the capability to sound an alarm. In addition, the relay 4 may be capable of
`
`providing telemetered characteristic sensor transceiver 100 data from the sensor set 10, as well
`
`as other data, to a remotely located individual via a modem connected to the relay 4 for display
`
`on a monitor, pager or the like. The relay 4 may also be used to transfer information from a
`
`remote device to the transceiver 100.
`
`[0039]
`
`Referring to FIG. 10, data may be exchanged between the transceiver 100 and a
`
`remotely located computer 6 such as a personal computer (PC), personal digital assistant (PDA),
`
`or the like, through a communication station 8 over communication lines ( e.g., modem or
`
`wireless connection). In some embodiments, the communication station 8 may be omitted such
`
`that the transceiver 100 directly connects to the computer 6 via the modem or wireless
`
`connection. In further embodiments, the telemetered characteristic sensor transceiver 100
`
`connects to an RF programmer, which acts as a relay, or shuttle, for data communication
`
`between the sensor set 10 and a PC, PDA, communication station, data processor, or the like. In
`
`further alternatives, t
