Patent number: 11864767Abstract: The invention is an implantable magnetic anastomosis device having an exoskeleton that directs self-assembly. The design allows the device to be delivered in a linear configuration using a minimally-invasive technique, such as endoscopy or laparoscopy, whereupon the device self-assembles into, e.g., a polygon. A coupled set of polygons define a circumscribed tissue that can be perforated, or the tissue can be allowed to naturally necrose and perforate. The device can be used to create anastomoses in a variety of tissues, such as tissues found in the gastrointestinal, renal/urinary, and reproductive tracts. New procedures for using anastomoses, e.g., surgical bypass are also disclosed.Type: GrantFiled: September 25, 2020Date of Patent: January 9, 2024Assignee: G.I. Windows, Inc.Inventors: Robert F.

Patent number: 11779731Abstract: Disclosed herein is a delivery catheter for implanting a leadless biostimulator. The delivery catheter includes a shaft and a tubular body having a lumen and an atraumatic end. The atraumatic end includes at least one of a braided, woven or mesh construction configured to facilitate the atraumatic end changing diameter. When a distal portion of the shaft is coupled to a proximal region of the leadless biostimulator, at least one of distally displacing the tubular body relative to the shaft or proximally displacing the shaft relative to the tubular body causes the leadless biostimulator to be received in the volume of the atraumatic end and the atraumatic end to encompass the leadless biostimulator. Conversely, at least one of proximally displacing the tubular body relative to the shaft or distally displacing the shaft relative to the tubular body causes the leadless biostimulator to exit the volume of the atraumatic end.Type: GrantFiled: April 10, 2020Date of Patent: October 10, 2023Assignee: PACESETTER, INC.Inventors: Tracee Eidenschink, Thomas B.

Patent number: 11771431Abstract: An anastomosis assist tool comprises a body unit extending in a predetermined advancing direction, and an insertion unit arranged at the tip of the body unit. The body unit includes an anastomosis assist part having an approximately constant cross-sectional shape in a plane perpendicular to the advancing direction. The anastomosis assist part includes a projection projecting outwardly as viewed in the cross section and extending in the advancing direction. The insertion unit includes a tapered part of a diameter decreasing gradually toward a tip. When the insertion unit and a part of the body unit are inserted into a vessel, the projection of the anastomosis assist part of the body unit abuts on the inner wall of the vessel. This makes it unlikely that the inner wall of the vessel will stick to the body unit at a site other than a point abutting on the projection.Type: GrantFiled: March 23, 2022Date of Patent: October 3, 2023Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Eiji Kobayashi, Hiroo Kasamatsu, Shinji Torai, Syuhei Yoshimoto
