`INC.’S NOTICE OF APPEAL UNDER 37 C.F.R. § 90.2(a)

`
`

`

`Pursuant to 35 U.S.C. §§ 141-144, 319, and 37 C.F.R.§ 90.2(a), notice is
`
`hereby given that Petitioners Medtronic, Inc. and Medtronic Vascular, Inc.

`Patent Trial and Appeal Board (“Board”) in IPR2020-01342, and from all
`
`underlying orders, decisions, rulings, and opinions. A copy of the Final Written

`
`In accordance with 37 C.F.R. § 90.2(a)(3)(ii), Medtronic further indicates
`
`that the issues on appeal may include, but are not limited to, whether the Board
`
`erred in determining that claims 1, 2, 4, 5, and 7-14 of U.S. Patent Number
`
`8,142,413 were not shown to be unpatentable under 35 U.S.C. § 103, any findings
`
`supporting or related to the Board’s determination, and all other issues decided
`
`adversely to Medtronic in any order, decision, ruling, and/or opinion, including but
`
`not limited to the Board’s failure to properly consider evidence of record, the
`
`Board’s legal errors in undertaking the obviousness analysis, and the Board’s
`
`findings that conflict with the evidence of record and are not supported by
`
`substantial evidence.
`

`
`A guide catheteris typically seated into the opening or ostium of
`the artery to be treated and a guidewire or other instrumentis
`passed through the lumen of the guide catheter and inserted into
`the artery beyond the occlusion or stenosis. Crossing tough
`lesions can create enough backward force to dislodge the guide
`catheter from the ostium of the artery being treated. This can
`makeit difficult or impossible for the interventional cardiologist
`to treat certain forms of coronary artery disease.
`
`from a main artery. Ex. 1001, Abstract.
`
`Accordingto the ’413 patent, interventional cardiology procedures
`
`often include inserting guidewires or other instruments through catheters
`
`into coronary arteries that branch off from the aorta. Jd. at 1:21-23.
`
`In coronary artery disease, atherosclerotic plaques or other lesions may
`
`narrow or occlude the coronary arteries. Jd. at 1:26-30. The ’413 patent
`
`states that “[n]arrowing is referred to as stenosis.” Jd. at 1:30-31.
`
`“In treating a stenosis, a guide catheteris typically inserted through the aorta
`
`and into the ostium of the coronary artery,” sometimes with the aid ofa
`
`guidewire. /d. at 1:35-37. The ’413 patent further states as follows:
`
`Id. at 1:37-45. The ’413 patent discusses “four categories” of “[p]rior
`
`attempts to provide support to the guiding catheter to prevent backward
`
`dislodgement from the coronary ostium (referred to as ‘backup support’),”
`
`consisting of: (1) “guiding catheters that, through a combination of shape
`
`

`

`IPR2020-01342
`Patent 8,142,413 B2
`
`and stiffness, are configured to draw backup support from engaging the wall
`
`of the aortic arch;” (2) “guiding catheters that include a retractable
`
`appendage;”(3) guide catheters that have apportion that seeks to expand
`
`laterally;” and, (4) “placement of a smaller guide catheter within a larger
`
`guide catheter in order to provide add support.” Jd. at 1:46-2:39. The
`
`’413 patent identifies various deficiencies with these prior attempts,
`
`including an increased risk of damageto the aortic wall and mechanical
`
`complexity. See id. Specifically, with regard to the fourth category of prior
`
`attempts, the ’413 patent states as follows:

`
`This technique is used in order to provide a method of deep
`seating the guide catheter within the ostium of the coronary
`artery. Deep seating refers to inserting the catheter more deeply
`into the ostium of the coronary artery than typically has been
`done before. Unfortunately, deep seating by this technique with
`a commonly available guide catheter creates the risk that the
`relatively stiff, fixed curve, guide catheter will damage the
`coronary artery. This damage may lead to dissection of the
`coronary artery when the catheter is advanced past the ostium.
`Several other problems arise when using a standard guide
`catheter in this catheter-in-a-catheter fashion. First, the inner
`catheters must be substantially longer than the one hundred
`centimeter guide catheter. Second, a new hemostasis valve must
`be placed on the inner guide catheter which prevents the larger
`guide catheter from being used for contrast injections or pressure
`measurements. Third, the smaller guide catheter still must be
`inserted into the coronary vessel with great care since the smaller
`guide catheter has no tapered transition or dilator at its tip and
`does not run overa standard 0.014 inch guidewire.
`
`Id. at 2:30-50. The ’413 patent states “a system that would be deliverable
`
`through standard guide catheters for providing backup support by providing
`
`the ability to effectively create deep seating in the ostium of the coronary
`
`artery” would be beneficial to “the interventional cardiologyart.” Jd.
`
`at 2:51-55.
`
`

`

`IPR2020-01342
`Patent 8,142,413 B2
`
`The ’413 patent describes “a coaxial guide catheter that is deliverable
`
`through standard catheters by utilizing a guidewire rail segment to permit
`
`delivery without blocking use of the guide catheter.” Jd. at 2:59-62. “The
`
`coaxial guide catheter preferably includes a tapered inner catheter that runs
`
`over a standard 0.014 inch coronary guidewire to allow atraumatic
`
`placement within the coronary artery,” allowing “removal of the tapered
`
`inner catheter after the coaxial guide catheter is in place.” Jd. at 2:62-67.
`
`Figures 1 and 2, reproduced below, show a coaxial guide catheter and a
`
`tapered inner catheter as described in the ’413 patent:

`In operation, a guide catheter 56 is inserted into a major blood
`vessel in the body such as aortic arch 58 over guidewire 64 and
`
`Figures 8 and 9 are schematic illustrations of guide catheter 56 with coaxial
`
`guide catheter 12 inserted into ostium 60 of coronary artery 62. Jd. at 5:43-
`
`49, 7:53-55, 7:67-8:4. The catheter assembly of Figure 8 includes optional
`
`tapered inner catheter 14, whereas the apparatus of Figure 9 does not. Jd.
`
`The *413 patent states “the presence of coaxial guide catheter 12
`
`within guide catheter 56” provides “improved distal anchoring of guide
`
`catheter 56 and coaxial guide catheter 56” and “stiffer back up support than
`
`guide catheter 56 alone.” Jd. at 7:67-8:6. The ’413 patent describes in
`
`detail a methodofuse, as follows:
`
`

`

`IPR2020-01342
`Patent 8,142,413 B2
`
`Id. at 9:51-10:15; see also id. at 1:23—26 (stating that “the term
`
`the distal end 68 of guide catheter 56 is brought into proximity
`of ostium 60 of a smaller branch blood vessel, such as coronary
`artery 62, that it is desired to enter. Coaxial guide catheter 12,
`with tapered inner catheter 14,
`is
`inserted through guide
`catheter56 and over guidewire 64. Guide
`catheter 56,
`guidewire 64, coaxial guide catheter 12, and tapered inner
`catheter 14 are manipulated to insert tapered innercathetertip 42
`into the ostium 60 of the blood vessel that branchesoff from the
`major blood vessel. The bumptip 22 of coaxial guide catheter 12
`is inserted with tapered innercatheter tip 42 well into ostium 60
`of coronary artery 62 or other blood vessel until bump tip 22 of
`coaxial guide catheter 12 achieves a deep seated position.
`Tapered inner catheter 14 is then withdrawn from the lumen of
`coaxial guide catheter 12.
`An interventional cardiology
`treatment device such as a catheter bearing a stent or a balloon
`(not shown)is then inserted through the lumen of coaxial guide
`catheter 12 which remainsinside guide catheter 56.
`Whenthe interventional cardiology device reachesa steno sis
`or blockage in coronary artery 62 or another branch blood vessel,
`force may be applied to the interventional cardiology device
`catheter while reinforced portion 18 and rigid portion 20 of
`coaxial guide catheter 12 provide back up support. The back
`force that would tend to dislodge bumptip 22 from a deep seated
`position in the ostium in the branch blood vessel is transferred
`through reinforced portion 18 to rigid portion 20 of coaxial guide
`catheter 12. A physician may apply a force to the proximal end
`of the coaxial guide catheter 12 to resist dislodging of bump
`tip 22 from the ostium ofthe branchartery.

`‘interventional cardiology devices’ is to be understood to include but not be
`
`limited to guidewires, balloon catheters, stents and stent catheters”). Patent
`
`Owner summarizes the method described in the ’413 patent and notes the
`
`use of the tapered inner catheter is optional. See PO Resp. 3 (stating that
`
`“To|ptionally, a tapered inner catheter may be inserted with the coaxial guide
`
`catheter and advancedto the second vessel, and removed before an

`
`2. Illustrative Claims
`
`Independent claim 1, reproduced below,is illustrative of the
`
`challenged claims.
`
`[1a] inserting the standard guide catheterinto a first artery
`over a guidewire, the standard guide catheter havinga distal end;
`
`[1b] positioning the distal end of the standard guide
`catheter in a branch artery that branchesoff from thefirst artery;
`
`[1c] inserting a flexible tip portion of a coaxial guide
`catheter defining a tubular structure having a circular cross-
`section and a length that is shorter than the predefined length of
`the continuous lumen of the standard guide catheter, into the
`continuous lumen of the standard guide catheter, and,
`
`[1d] further inserting a substantially rigid portion that is
`proximal of, operably connected to, and more rigid along a
`longitudinal axis than the flexible tip portion, into the continuous
`lumen of the standard guide catheter,
`the substantially rigid
`portion defining a rail structure without a lumen and having a
`maximal cross-sectional dimension at a proximal portion that is
`smaller than the cross-sectional outer diameterofthe flexible tip
`portion and having a length that, when combinedwith the length
`of the flexible distal tip portion, defines a total length of the
`
`IPR2020-01342
`Patent 8,142,413 B2
`
`[interventional cardiology device] is inserted into the coaxial guide catheter”
`
`[lpre.] A method of providing backup support for an
`1.
`interventional cardiology device for use in the coronary
`vasculature, the interventional cardiology device being adapted
`to be passed through a standard guide catheter, the standard guide
`catheter having a continuous lumen extending for a predefined
`length from a proximal end at a hemostatic valve to a distal end
`adapted to be placed in a branch artery, the continuous lumen of
`the guide catheter having a circular cross-sectional
`inner
`diameter sized such that interventional cardiology devices are
`insertable into and through the lumen, the method comprising:
