`
`TRANSCUTANEOUSANALYTE SENSOR
`
`FIELD OF THE INVENTION
`0001. The present invention relates generally to systems
`and methods for measuring an analyte in a host. More par
`ticularly, the present invention relates to Systems and methods
`for transcutaneous measurement of glucose in a host.
`
`BACKGROUND OF THE INVENTION
`0002 Diabetes mellitus is a disorder in which the pancreas
`cannot create Sufficient insulin (Type I or insulin dependent)
`and/or in which insulin is not effective (Type 2 or non-insulin
`dependent). In the diabetic state, the victim suffers from high
`blood Sugar, which can cause an array of physiological
`derangements associated with the deterioration of Small
`blood vessels, for example, kidney failure, skin ulcers, or
`bleeding into the vitreous of the eye. A hypoglycemic reac
`tion (low blood Sugar) can be induced by an inadvertent
`overdose of insulin, or after a normal dose of insulin or
`glucose-lowering agent accompanied by extraordinary exer
`cise or insufficient food intake.
`0003 Conventionally, a person with diabetes carries a
`self-monitoring blood glucose (SMBG) monitor, which typi
`cally requires uncomfortable fingerpricking methods. Due to
`the lack of comfort and convenience, a person with diabetes
`normally only measures his or her glucose levels two to four
`times per day. Unfortunately, such time intervals are so far
`spread apart that the person with diabetes likely finds out too
`late of a hyperglycemic or hypoglycemic condition, some
`times incurring dangerous side effects. It is not only unlikely
`that a person with diabetes will take a timely SMBG value, it
`is also likely that he or she will not know if his or her blood
`glucose value is going up (higher) or down (lower) based on
`conventional method. This inhibits the ability to make edu
`cated insulin therapy decisions.
`
`SUMMARY OF THE INVENTION
`0004. In a first aspect, a sensor System for measuring an
`analyte concentration in a host is provided, the system com
`prising a sensor configured to continuously measure an ana
`lyte concentration in a host; a housing configured to receive
`the sensor, wherein the housing is adapted for placement
`adjacent to the host's skin; an electronics unit releasably
`attached to the housing, wherein the electronics unit is opera
`tively connected to the sensor and comprises a processor
`module configured to provide a signal associated with the
`analyte concentration in the host, and wherein the processor
`module is further configured to assemble a data packet for
`transmission; and an antenna configured for radiating or
`receiving a radio frequency transmission, wherein the
`antenna is located remote from the electronics unit.
`0005. In an embodiment of the first aspect, the system
`further comprises an adhesive layer disposed on the housing
`and configured to adhere the housing to the host's skin,
`wherein the antenna is located in the adhesive layer or on the
`adhesive layer.
`0006. In an embodiment of the first aspect, the adhesive
`layer is configured for use with only one sensor and the
`electronics unit is configured for reuse with more than one
`SSO.

`extends Substantially around a periphery of the housing.
`0010. In an embodiment of the first aspect, the system
`further comprises a power source configured and arranged to
`power at least one of the sensor and the electronics unit.
`0011. In an embodiment of the first aspect, the system
`further comprises an adhesive layer disposed on the housing
`and configured to adhere the housing to the host's skin,
`wherein the power source is located in the adhesive or on the
`adhesive.
`0012. In an embodiment of the first aspect, the adhesive
`layer is configured for use with only one sensor and the
`electronics unit is configured for reuse with more than one
`SSO.
`0013. In an embodiment of the first aspect, the power
`source comprises a thin and flexible battery.
`0014. In an embodiment of the first aspect, the power
`Source is located in the housing or on the housing.
`0015. In an embodiment of the first aspect, the housing is
`configured for use with only one sensor and the electronics
`unit is configured for reuse with more than one sensor.
`0016. In an embodiment of the first aspect, a height of the
`electronics unit is no more than about 0.250 inches in its
`Smallest dimension.
`0017. In an embodiment of the first aspect, an overall
`height of the system is no more than about 0.250 inches in its
`Smallest dimension.
`0018. In an embodiment of the first aspect, the sensor is
`configured for insertion into the host's tissue.
`0019. In a second aspect, a sensor System for measuring an
`analyte concentration in a host is provided, the system com
`prising a sensor configured for insertion into a host's tissue,
`wherein the sensor is configured to continuously measure an
`analyte concentration in a host; a housing configured to
`receive the sensor, wherein the housing is adapted for place
`ment adjacent to the host's skin; and an electronics unit
`releasably attached to the housing, wherein the electronics
`unit is operatively connected to the sensor and comprises a
`processor module configured to provide a signal associated
`with the analyte concentration in the host.
`0020. In an embodiment of the second aspect, the housing
`comprises a flexible material, and wherein the electronics unit
`and housing are configured and arranged such that the elec
`tronics unit is released from the housing by a flexing of the
`housing.
`0021. In an embodiment of the second aspect, the housing
`is configured for use with only one sensor and the electronics
`unit is configured for reuse with more than one sensor, and
`wherein the housing and electronics unit are configured Such
`that the housing physically breaks upon release of the elec
`tronics unit.
`0022. In an embodiment of the second aspect, the system
`further comprises a tool configured and arranged to assist a
`user in releasing the electronics unit from the housing.
`0023. In an embodiment of the second aspect, the system
`further comprises an antenna configured for radiating or
