Patent number: 8540759Abstract: A stent delivery system having rapid exchange capabilities for delivering a self-expandable stent. The system includes a delivery catheter and a sheath positionable in the lumen of the delivery catheter. The delivery catheter includes an elongate shaft extending distally from a hub assembly. The elongate shaft includes a lumen extending therethrough and a guidewire port providing access to the lumen at a location intermediate the proximal and distal ends of the elongate shaft. The sheath is positionable in the lumen of the delivery catheter such that the sheath extends across the guidewire port to close off the guidewire port to allow a stent to be passed through the sheath from proximal of the guidewire port to distal of the guidewire port.Type: GrantFiled: October 20, 2011Date of Patent: September 24, 2013Assignees: Stryker Corporation, Stryker NV Operations LimitedInventor: Stephen C. Porter

Publication number: 20120123466Abstract: A device for removing a blood clot from a lumen of a vessel, the device comprising a pusher and an expandable tubular cage fixedly engaged to the pusher. The tubular cage has a proximal end, a distal end, and a wall extending therebetween. The wall comprises a plurality of bands of cells axially arranged along the tubular cage, wherein one band of cells comprises at least one skiving cell having a cell wall with a proximal portion, a distal portion, and a central portion between the proximal portion and the distal portion. The central portion deforms radially inward in response to a radially applied force to a greater extent than the distal portion.Type: ApplicationFiled: November 8, 2011Publication date: May 17, 2012Applicants: STRYKER NV OPERATIONS, LTD., STRYKER CORPORATIONInventors: Stephen C.

Publication number: 20110054504Abstract: A vascular recanalization device for re-establishing blood flow through a vessel lumen. The vascular recanalization device includes an elongate wire and an expandable cage slidably coupled to the elongate wire. The expandable cage includes a proximal collar slidably disposed on the elongate wire and a distal collar slidably disposed on the elongate wire. A central stop is secured to the elongate wire intermediate the proximal collar and the distal collar. A proximal stop is located proximal of the proximal collar of the expandable cage, and a distal stop is located distal of the distal collar of the expandable cage. The proximal collar is slidable along the elongate wire between the proximal stop and the central stop, and the distal collar is slidable along the elongate wire between the central stop and the distal stop.Type: ApplicationFiled: August 27, 2010Publication date: March 3, 2011Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventor: Stephen C.

Publication number: 20100222803Abstract: Apparatus and methods for treating a wall of an aneurysm formed in a vessel includes introducing a tubular member into the body lumen until a distal end of the tubular member is located within the aneurysm. A fluid is delivered via a lumen of the tubular member into the aneurysm to at least partially de-endothelialize the wall of the aneurysm, thereby causing an endothelium of the wall to generate fibrous tissue to strengthen the wall of the aneurysm.Type: ApplicationFiled: May 14, 2010Publication date: September 2, 2010Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Paul S. Seifert, Elaine Lee, Michael P. Wallace, Stephen C. Porter
