`IPR2020-00130
`Patent RE 45,380E
`
`I. PRELIMINARY STATEMENT
`Medtronic, Inc. and Medtronic Vascular, Inc. (“Petitioner”) request inter
`
`partes review (“IPR”) of claims 1-4, 6-9, and 12-21 (“Challenged Claims”) of U.S.
`
`Pat. No. RE 45,380 (“the ’380 patent,” Ex-1401). The ʼ380 patent is entitled
`
`Coaxial Guide Catheter for Interventional Cardiology Procedures and lists
`
`Howard Root et al. as inventors. Id., [54], [72]. The Challenged Claims were never
`
`subject to an Office Action, meaning there is no substantive file history for the
`
`ʼ380 patent.
`
`The ’380 patent describes a catheter system that reduces the likelihood of a
`
`guide catheter dislodging from the ostium of a coronary artery during the removal
`
`of a coronary stenosis. The purported invention requires a guide catheter (“GC”)
`
`and a guide extension catheter.1 The latter is inserted into and extended beyond the
`
`distal end of the GC (i.e., into a coronary branch artery). Id., Abstract, Figs. 8-9. In
`
`so doing, the guide extension catheter delivers “backup support by providing the
`
`
`1 The ’380 patent refers to the guide extension catheter as a “coaxial guide
`
`catheter.” Ex-1405, ¶¶ 71 n.6, 118. A POSITA knew that the “coaxial guide
`
`catheter” of the ’380 patent was commonly understood as a guide extension
`
`catheter because it extends the guide catheter further into the coronary artery. Id.;
`
`see also Ex-1409, 5:49-52 (referring to body 12 “as a guide catheter extension”).
`
`
`

`Patent RE 45,380E
`ability to effectively create deep seating in the ostium of the coronary artery,”
`
`thereby preventing the GC from dislodging from the ostium. Id., 3:1-5.
`
`The ’380 patent admits that the use of a guide extension catheter inside an
`
`outer guide catheter was known. Id., 2:40-56 (describing the use of a “smaller
`
`guide catheter within a larger guide catheter”). Indeed, such a catheter-in-a-catheter
`
`assembly was well-known in the art and described as a “mother-and-child
`
`assembly.” Ex-1405, ¶¶ 70-80. The child catheter (red in below figure) (i.e., the
`
`guide extension catheter) is essentially a tube that is inserted into and extends
`
`beyond the GC (blue in below figure) (i.e., the mother catheter) into the coronary
`
`artery. Id., ¶ 70.

`
`
`
`

`

`IPR2020-00130
`
`Patent RE 45,380E
`Ex-1454, Fig. 2 (color and labels added).
`
`The child catheter in the mother-and-child assembly had a continuous lumen
`
`that was longer than the lumen of the guide (“mother”) catheter. Id. The ’380
`
`patent alleges that such a design had certain drawbacks (Ex-1401, 2:57-67; Ex-
`
`1405, ¶¶ 81-89) and modifies the child catheter (of the mother-and-child assembly)
`
`to have two parts: (i) a long thin pushrod (ii) coupled to a short distal lumen (i.e.,
`
`tube) that is highly flexible so it can extend deep into the coronary artery.
`
`Ex-1401, Fig. 1 (annotations and color added).
`
`
`
`But such child catheters that served as guide extension catheters and had a
`
`short lumen connected to a long thin pushrod were already well-known in the art,
`
`as evidenced by U.S. Patent No. 5,439,445 (“Kontos”), which issued more than ten
`
`years before the earliest purported priority date of the ʼ380 patent.

`
`
`
`Ex-1409, Fig. 6B (annotations and color added).
`
`
`
`For the reasons set forth herein, there is more than a reasonable likelihood
`
`that the Challenged Claims of the ’380 patent are unpatentable. Accordingly,
`
`Petitioner respectfully requests institution of a trial and cancellation/invalidation of
`
`
`
`the Challenged Claims.
`
`II. MANDATORY NOTICES UNDER 37 C.F.R. § 42.8
`
`A. Real Party-in-Interest
`
`Pursuant to 37 C.F.R. § 42.8(b)(1), Petitioner identifies Medtronic, Inc. and
`
`Medtronic Vascular, Inc. as real parties-in-interest. Medtronic plc is the ultimate
`
`parent of both entities.
`
`B. Related Matters
`
`Pursuant to 37 C.F.R. § 42.8(b)(2), Petitioner identifies that the ’380 patent
`
`is currently the subject of litigation in two separate actions in the U.S. District
`
`Court for the District of Minnesota: (i) Vascular Solutions LLC, et al. v. Medtronic,
`
`
`
`4
`
`

`

`IPR2020-00130
`
`Patent RE 45,380E
`Inc., et al., No. 19-cv-01760 (D. Minn., filed July 2, 2019); and (ii) QXMedical,
`
`LLC v. Vascular Solutions, LLC, No. 17-cv-01969 (D. Minn., filed June 8, 2017)
`
`(“QXMedical Litigation”).
`
`Further, the ’380 patent is a reissue of U.S. Pat. No. 8,292,850 (“the ʼ850
`
`patent). The ʼ850 patent was previously the subject of litigation (i) in the U.S.
`
`District Court for the District of Minnesota in Vascular Solutions, Inc. v. Boston
`
`Scientific Corp., No. 13-cv-01172 (D. Minn., filed May 16, 2013), and (ii) at the
`
`PTAB in Boston Scientific Corp. v. Vascular Solutions, Inc., IPR2014-00762,
`
`IPR2014-00763 (P.T.A.B., terminated Aug. 11, 2014).
`
`Petitioner is also concurrently filing another petition for IPR challenging the
`
`ʼ380 patent based on prior art references having different priority dates and
`
`disclosures than the references discussed herein.

`
`
`IV. BACKGROUND
`
`A. Overview of the Technology
`
`Coronary artery disease (“CAD”) occurs when plaque buildup narrows the
`
`arterial lumen. Ex-1405, ¶¶ 28, 30-32. This narrowing, sometimes called a stenosis,
`
`restricts blood flow and increases the risk of heart attack or stroke. Id. In response,
`
`physicians developed percutaneous coronary interventional (“PCI”) procedures
`
`that use catheter-based technologies inserted through the femoral or radial artery,
`
`and thus can treat CAD without the need for open-heart surgery. Id., ¶¶ 29, 34-40.
`
`
`2 This Petition is also supported by the Declarations of Stephen JD Brecker, MD
`
`(Ex-1405) and Richard A Hillstead, PhD (Ex-1442), as experts in the field of the
`
`ʼ380 patent. Petitioner also submits the declaration of Sylvia S. Hall-Ellis, PhD
`
`(Ex-1478) to support the authenticity and public availability of the documents cited
`
`herein.

`
`Patent RE 45,380E
`PCI was developed more than forty years ago, and although its catheter-
`
`based technology has advanced, the basic components of PCI have remained
`
`largely unchanged. Id., ¶¶ 33, 41. During PCI, after a physician uses a hollow
`
`needle to gain access to the patient’s vasculature, a guide catheter is introduced and
`
`advanced along the vasculature until its distal end is placed—by a few
`
`millimeters—in the ostium of a coronary artery. Id., ¶¶ 34, 42-55. A hemostatic
`
`valve is placed at the proximal end of the guide catheter and remains outside the
`
`patient’s body. Id., ¶¶ 35, 54. The hemostatic valve prevents blood from exiting the
`
`patient’s artery and keeps air from entering the bloodstream. Id.
`
`Another small diameter flexible guidewire can then be threaded through the
`
`lumen of the guide catheter to the target site. Id., ¶¶ 56-58. This guidewire serves
`
`as a guiderail to advance a therapeutic catheter through the guide catheter and to
`
`the occlusion. Id. The therapeutic catheter typically must then be passed through
`
`and beyond the occlusion in order to alleviate the stenosis. Id., ¶¶ 59-67. This last
`
`step—crossing the therapeutic catheter past the occlusion—creates backward force
`
`that can dislodge the guide catheter from the ostium. Id., ¶¶ 66-67. As discussed
`
`above, one way to ameliorate this backward force is to use a mother-and-child
`
`catheter assembly where the child catheter acts as an extension of the guide
`
`catheter into the coronary artery. Id., ¶¶ 68-80.

`B. Overview of the ’380 Patent
`The ’380 patent relates “generally to catheters used in interventional
`
`
`
`cardiology procedures.” Ex-1401, 1:32-35. In particular, the ʼ380 patent discloses a
`
`coaxial guide catheter (also known as an extension catheter) that extends “beyond
`
`the distal end of the guide catheter, and … into [a] branch artery.” Id., Abstract.
`
`The catheter assembly purports to have the benefit of a mother-and-child
`
`assembly—it “assists in resisting both the axial forces and the shearing forces that
`
`tend to dislodge a guide catheter from the ostium of a branch artery.” Id., 5:23-27;
`
`Ex-1405, ¶¶ 118-19.
`
`
`
`The ’380 patent explains that the guide extension catheter 12 has a tubular
`
`portion that includes flexible distal tip 16 (pink) and reinforced portion 18 (blue),
`
`as well as rigid portion 20 (yellow). Id., 3:51-53, 6:34-36, Fig. 1. Color has been
`
`added to Figure 1, below, which has been annotated with the language of claim 1.3
`
`
`3 In claim 1 “a flexible tip portion” defines “a tubular structure.” The “tubular
`
`structure” in claim 1 further “includes a flexible cylindrical distal tip portion and a
`
`flexible cylindrical reinforced portion.” Claim 12 describes the guide extension
`
`catheter using different language. Specifically, claim 12 recites “a flexible tip
`
`portion defining a tubular structure,” and a proximally-located “reinforced
`
`portion.”

`Id., Fig. 1 (annotations and color added).
`
`
`The patent also addresses structural characteristics of the transition at or near
`
`
`
`the extension catheter’s reinforced and rigid portions, sometimes referred to as a
`
`“side opening” (red circle), which may have an “inclined slope.” Id., 6:62-7:11,
`
`Figs. 4, 13-16; Ex-1405, ¶ 121.

`
`
`
`As shown below, the ’380 patent describes that extension catheter 12 is
`
`deployed through guide catheter 56 (no color). A guidewire 64 and balloon (green)
`
`extend from the distal tip (pink) of the extension catheter. Moving distally to
`
`proximally, the extension catheter’s distal tip (pink) and a reinforced portion (blue)
`
`extend out of the distal tip of guide catheter 56. Ex-1405, ¶ 122.

`C. Prosecution History of the ’380 Patent
`The parent ʼ850 patent issued without an Office Action. See generally Ex-
`
`
`
`1402. According to the Examiner, the claims of the ʼ850 patent were allowable
`
`because “adding a guide catheter to the claimed rail structure with the claimed
`
`flexible tip that is insertable through a hemostatic valve is not taught or suggested
`
`by the prior art.” Ex-1402 at 83 (Notice of Allowance at 3). In other words, he
`
`believed that a mother-and-child assembly—where the child catheter is
`
`characterized by a short distal lumen coupled to a proximally located pushrod—
`
`was not described in the art. The Examiner, however, was not aware of Kontos.
`
`Patent Owner sought reissuance in 2013, and as with the original prosecution, the
`
`claims of the ’380 patent issued without an Office Action. See generally Ex-1403.
`
`V. PERSON OF ORDINARY SKILL IN THE ART
`
`If a person of ordinary skill in the art (“POSITA”) was a medical doctor, s/he
`
`would have had (a) a medical degree, (b) completed a coronary intervention
`
`training program, and (c) experience working as an interventional cardiologist.
`
`Alternatively, if a POSITA was an engineer s/he would have had (a) an
`
`undergraduate degree in engineering, such as mechanical or biomedical
`
`engineering; and (b) at least three years of experience designing medical devices,
`
`including catheters or catheter-deployable devices. Extensive experience and
`
`technical training might substitute for education, and advanced degrees might
`
`
`
`12
`
`

`

`IPR2020-00130
`
`Patent RE 45,380E
`substitute for experience. Additionally, a POSITA with a medical degree may have
`
`access to a POSITA with an engineering degree, and a POSITA with an
`
`engineering degree may have access to one with a medical degree. Ex-1405, ¶ 27;
`
`Ex-1442, ¶¶ 18-19.
`
`VI. CLAIM CONSTRUCTION
`
`Claim terms are typically given their ordinary and customary meanings as
`
`would have been understood by a POSITA at the time of the invention. Phillips v.
`
`AWH Corp., 415 F.3d 1303, 1312-16, (Fed. Cir. 2005) (en banc). When, as here,
`
`claim terms have been construed by a district court, those constructions are
`
`properly considered during an IPR. 37 C.F.R. § 42.100(b). In the QXMedical
`
`Litigation, Patent Owner stipulated to the following constructions:
`
`• “reinforced portion”: “portion made stronger by additional material or
`
`support” (Ex-1412 at 2)
`
`• “interventional cardiology device(s)”: “devices including, but not limited
`
`to, guidewires, balloon catheters, stents, and stent catheters” (Compare
`
`Ex-1412 at 21 (Dkt. 36-1), with Ex-1464 at 1 n.1)
`
`Further, Patent Owner advanced,4 and the district court adopted, the following
`
`
`4 The full list of constructions advanced by Patent Owner in the QXMedical
`
`Litigation is found at Ex-1412 (Dkt. 36-1).
`
`
`
`13
`
`

`

`IPR2020-00130
`Patent RE 45,380E
`constructions:
`
`
`
`• “substantially rigid”: “rigid enough to allow the device to be advanced
`
`within the guide catheter” (Ex-1412 at 2 (Dkt. 36-1); Ex-1413 at 15)
`
`• “rail structure”: “structure that facilitates monorail or sliding rail
`
`delivery” (Ex-1413 at 20)
`
`Additionally, the district court provided the following construction:
`
`• “side opening”: “need no construction and will be given [its] plain and
`
`ordinary meaning” (Id. at 26)
`
`• “lumen”: “the cavity of a tube” (Id. at 25).
`
`Petitioner agrees with the above constructions for purposes of this IPR5 (Ex-1405,
`
`¶¶ 123-29) and proposes the following additional constructions:
`
`A. “placed in the branch artery” (cls. 1, 12)
`
` Claims 1 and 12 recite, inter alia, “a guide catheter having … a distal end
`
`adapted to be placed in the branch artery.” In the context of the ’380 patent,
`
`“placed in the branch artery” includes “placement in the ostium of a coronary
`
`artery.” Ex-1405, ¶¶ 133-34. For instance, the ’380 patent notes, in its background,
`
`the well-understood fact that a “guide catheter is inserted … into the ostium of the
`
`
`5 Petitioner proposes these constructions for purposes of this IPR only and reserves
`
`the right to raise different constructions in other forums.

`coronary artery.” Ex-1401, 1:53-54. This is further shown in Figures 7 and 8
`
`(reproduced below), and confirmed by other description in the ’380 patent. The
`
`patent describes that an GC is “inserted into the ostium of a branch artery where it
`
`branches off from a larger artery.” Id., 4:63-5:2, Figs. 7-8.
