Patent number: 8888796Abstract: A device for tensioning barbed sutures used for securing tissue or prosthetic devices includes a handle, and a shaft having a proximal end connected with the handle and a distal end remote therefrom. The distal end of the shaft includes a pressure applying surface for pressing against the tissue and the prosthetic devices. The tensioning device includes a pair of grooves extending through the shaft from the pressure applying surface at the distal end of the shaft toward the proximal end of the shaft. A barbed suture is tensioned by aligning a first section of the suture in the first groove and a second section of the suture in the second groove. After the first and second suture sections are aligned in the grooves, the proximal ends of the sections may be pulled for applying tension to the suture.Type: GrantFiled: June 7, 2008Date of Patent: November 18, 2014Assignee: Ethicon, Inc.Inventors: David Lindh, Sr., Jesse G.

Patent number: 8100941Abstract: A barbed suture includes a flexible thread having a leading end and a trailing end, and a plurality of barbs projecting from the flexible thread. The flexible thread has a plurality of web-like openings formed therein, whereby each of the openings is disposed adjacent one of the barbs. The openings enhance the flexibility of the barbs and provide space for the barbs to collapse inwardly as the leading end of the flexible thread is pulled through a medium such as tissue. When the barbs are collapsed, the diameter of the barbed sections is preferably no greater than the diameter of the non-barbed sections. In one embodiment, a support element interconnects at least one of the barbs and the flexible thread for reinforcing the at least one barb and resisting flexure of the at least one barb toward the leading end of the flexible thread.Type: GrantFiled: June 17, 2008Date of Patent: January 24, 2012Assignee: Ethicon, Inc.Inventors: David Lindh, Sr., Jesse G.

Patent number: 6712859Abstract: A hernia repair prosthesis with an occlusive member for inserting into and/or backing the herniated tissue. The occlusive member is convertible from a first configuration with a first axial length and first major radial extent to a second configuration with a second axial length and a second major radial extent. The second axial length is less than the first axial length and the second major radial extent is larger than the first major radial extent. The occlusive member has a pair of subsections, each having an apex, lands and pleats and each flaring outwardly therefrom towards a terminal end. The apexes are disposed at opposite ends of the occlusive member with the terminal ends overlapping. The pair of subsections are conjoined proximate the overlapping terminal ends. The terminal end of one or both of the subsections may be in the form of a conic flange mimicking the lands and pleats of the other subsection providing automatic alignment and nesting to aid in the attachment of the two subsections.Type: GrantFiled: June 28, 2001Date of Patent: March 30, 2004Assignee: Ethicon, Inc.Inventors: Robert A.
