Patent number: 7351258Abstract: An apparatus for facilitating securement of a vascular graft within a blood vessel, includes a shaft dimensioned for passage within a blood vessel and having an expansion member movable between a contracted condition and an expanded condition and a fastener array comprising at least one fastener disposed about a peripheral portion of the expansion member. The one fastener is deployable into a wall of the blood vessel upon movement of the expansion member to the expanded condition thereof, to thereby engage the vascular graft to secure the vascular graft to a wall of the blood vessel. The fastener array preferably includes a plurality of fasteners. The fasteners may be operatively connected to each other and releasably secured to the peripheral portion of the expansion member.Type: GrantFiled: April 18, 2002Date of Patent: April 1, 2008Assignee: The Research Foundation of State University of New York at Stony BrookInventors: John Ricotta, Benjamin S. Hsiao, Rajesh H. Somani

Patent number: 7335224Abstract: A retention system for retaining a stent graft (13) onto a deployment device (1) in which the stent graft has an exposed stent (11) at at least one end. The deployment device has a capsule (7) to receive the exposed stent during deployment and an arrangement to move the capsule to release the exposed stent when required. A release wire (17) associated with the deployment device engages a portion (19) of the exposed stent within the capsule to retain the exposed stent in the capsule. At least one retention loop (25) on the stent graft is connected around the release wire to prevent removal of the capsule from the exposed stent until the release wire has been removed from its engagement with the exposed stent within the capsule and the retention loop is released.Type: GrantFiled: October 12, 2004Date of Patent: February 26, 2008Assignees: William Cook Europe ApS, Cook IncorporatedInventor: Bent Øhlenschlæger

Patent number: 7329275Abstract: A delivery system for endoluminal deployment of a stent inside of a biocompatible graft cover minimizes obstruction of endoluminal fluid flow during deployment. The delivery system includes a stent sheath, a compressed stent underlying the stent sheath, and a graft overlying the stent sheath and releasably retained in a compressed state surrounding the sheath. The graft distal end is attached to the stent at or proximal the stent distal end, and the graft outer surface is exposed to the interior space of the lumen during deployment. The proximal end of the graft may be attached to the stent sheath by a releasable attachment adapted for release during deployment of the stent, or may be otherwise constrained, such as by heat deformation, to remain adjacent the outer circumference of the stent prior to deployment. The releasable attachment may be a suture that is severed by a pusher having a cutter therein.Type: GrantFiled: September 10, 2003Date of Patent: February 12, 2008Assignee: Boston Scientific Scimed, Inc.Inventor: Carl E.

Patent number: 7320697Abstract: Apparatus and methods are provided for use in filtering emboli from a vessel, wherein a vascular filter is disposed on a guide wire, the vascular filter having a support hoop disposed from a suspension strut so as to permit lateral eccentric displacement of the support hoop relative to a longitudinal axis of the guide wire. A blood permeable sac is affixed to the support hoop to form a mouth of the blood permeable sac. The support hoop is disposed obliquely relative to the guide wire and is capable of being properly used in a wide range of vessel diameters. The support hoop collapses the mouth of the blood permeable sac during removal of the vascular filter to prevent material from escaping from the sac. A delivery sheath and introducer sheath for use with the vascular filter of the present invention are also provided.Type: GrantFiled: December 8, 2003Date of Patent: January 22, 2008Assignee: Boston Scientific Scimed, Inc.Inventors: Jackson Demond, Marlon C.

Patent number: 7309341Abstract: A surgical tool or applier facilitates laparoscopic or endoscopic implantation through a single bodily tissue lumen of an anastomotic ring device for forming a hollow rivet type of attachment between tissue lumens. In addition to forming a puncture between apposite tissue walls at the anastomosis site, the applier assists or wholly actuates the anastomotic ring device and is retracted to deploy the actuated ring device. Illumination incorporated into a distal portion of a cannula enables confirmation of deployment.Type: GrantFiled: September 30, 2003Date of Patent: December 18, 2007Assignee: Ethicon Endo-Surgery, Inc.Inventors: Mark S.

Patent number: 7264632Abstract: A controlled stent-graft deployment delivery system (10 50 or 900) includes a stent-graft (30 or 63), a retractable primary sheath (40) containing the stent-graft in a first constrained diameter configuration, an outer tube (18) within the retractable primary sheath and within the stent-graft, and an inner tube (20) within the outer tube, where the inner tube and the outer tube both axially move relative to the retractable primary sheath and to each other. The system further includes a cap (15) coupled to a distal end of the inner tube and configured to retain at least a portion of a proximal area of the stent-graft in a radially compressed configuration. A distal assembly (100) provides controlled relative axial movement between the outer tube and the inner tube enabling the release of the proximal end (65, 67, 68, and 69) of the stent-graft from the cap and from the radially compressed configuration.Type: GrantFiled: June 5, 2003Date of Patent: September 4, 2007Assignee: Medtronic Vascular, Inc.Inventors: Michael T.
