Patent number: 11937810Abstract: Systems, devices and methods described herein relate to endovascular devices for delivering sutures for securing grafts or other objects to patient vessels. In some embodiments, a suture includes a set of two legs having proximal ends joined to each other and elongate bodies that extend parallel to one another such that the set of two legs form a U-shaped structure. A suture delivery system can include a housing configured to contain a suture in a flattened configuration, and a deployment element having a ribbon-shaped distal portion disposed in the housing and including a set of formations, where the housing and the set of formations of the deployment element are configured to collectively constrain the suture in the flattened configuration until the suture is released through the opening of the housing.Type: GrantFiled: May 23, 2023Date of Patent: March 26, 2024Assignee: Vesteck, Inc.Inventors: John K. Edoga, Thierry Richard, Edward Wulfman, Kent Stalker

Patent number: 11918450Abstract: Devices, systems, and methods for coupling a prosthetic implant to a fenestrated body are disclosed herein. In some embodiments, a branch stent graft is provided. The branch stent graft can include an engagement portion for engagement with an opening in a fenestrated body, such as a vessel wall or an aortic stent graft. The engagement portion of the branch stent graft can be coupled to the fenestrated body such that the branch stent graft can move, rotate or shift relative to the fenestrated body but such that axial movement of the branch stent graft is restricted and/or prevented.Type: GrantFiled: March 25, 2021Date of Patent: March 5, 2024Assignee: Bolton Medical, Inc.Inventors: Casey Torrance, Shannon Eubanks, Edward Wulfman, Thomas Douthitt

Patent number: 6800083Abstract: A rotational ablation atherectomy device including a flexible drive shaft and a compressible burr that may be inserted and extracted from a patient using a catheter having a diameter that is smaller than the operational diameter of the burr. In one embodiment, the burr includes a nose portion coupled to the drive shaft and one or more flexible abrasive disks disposed rearwardly from the nose portion. The flexible disks are foldable to be slidably received within a catheter. In another embodiment, the burr includes a support member coupled to the drive shaft, the support member having a resilient panel that spirals outwardly, forming a generally cylindrical ablation surface. The flexible panel can be elastically urged toward the support member and slidably inserted into the catheter. In a third embodiment, the burr includes a plurality of struts that are coupled to the drive shaft. An elastically compressible body disposed between the struts permits the struts to flex inwardly to reduce the burr diameter.Type: GrantFiled: April 9, 2001Date of Patent: October 5, 2004Assignee: SciMed Life Systems, Inc.Inventors: Thomas J.

Patent number: 6416526Abstract: An atherectomy burr has an operating diameter that is larger than the diameter of a catheter in which the burr is routed. The burr may include a polymeric balloon that is coated with an abrasive and that expands when the burr is rotated. Alternatively, the burr may include a polymeric tube that is coated with an abrasive and secured to the proximal end of the burr. When the burr is rotated, the polymeric tube expands by centrifugal force. Alternatively, the burr may comprise a metallic strip wound over a mandrel. When the strip is tightly coiled to the mandrel, its outer diameter decreases. The outer diameter of the burr increases as the metallic strip expands. In addition, the burr can be formed as a wire spring wound over a drive tube. The distal end of the spring is coupled to a nose cone that can move within a distal lumen in the drive tube. The maximum expansion of the burr is controlled by the distance that the nose cone can be retracted into the lumen.Type: GrantFiled: June 8, 2000Date of Patent: July 9, 2002Assignee: Scimed Life Systems, Inc.Inventors: Mark Wyzgala, Donald Baumgarten, Lucas S. Gordon, Eric B. Hamilton, Matt Hefner, Tom Hiblar, Edward Wulfman

Patent number: 6328750Abstract: An ablation burr has a body provided with an inner circumferential rim and an outer circumferential rim that are concentric and spaced longitudinally by a selected distance along the length of the burr. The outer circumferential rim has a generally smooth convex outer surface that reduces damage to a vessel wall or stent A leading surface of the burr extends between the inner and outer circumferential rims in a substantially uniform, concave manner. An abrasive, for example, diamond grit, is provided on the leading surface. The burr is selectively rotated by a drive shaft, causing the abrasive leading surface of the burr to ablate unwanted deposits. If desired, a wire extends co-axially through the body such that a distal end of the wire extends out of the distal end of the burr. An abrasive tip may be coupled to the distal end of the wire, and is selectively rotated, to ablate unwanted deposits.Type: GrantFiled: September 6, 2000Date of Patent: December 11, 2001Assignee: SciMed Life Systems, Inc.Inventors: Robert Lawrence Berry, Matt Hefner, Tom Hiblar, Joseph Pearce, Natalya Peskin, Edward Wulfman
