Patent number: 8556933Abstract: Surgical bolts are useful for solid visceral wound hemostasis. The devices utilize flexible, variable depth transfixing bolts that penetrate the viscera. These bolts bring the tissue into apposition and hold said tissue in apposition while the wound heals.

Patent number: 8252022Abstract: A closure device to be inserted at least partially through a blood vessel wall aperture in a blood vessel wall. The closure device includes at least two parts, an internal part and an external part. The internal part is adapted to be extended at least partially through the blood vessel wall aperture and into the lumen to at least partially block the blood vessel wall aperture. Each of the internal part and the external part consists essentially of a metal that biodegrades within a living being in a period of time that permits biological repair of the blood vessel wall in and around the blood vessel aperture.Type: GrantFiled: July 13, 2009Date of Patent: August 28, 2012Assignee: Vascular Solutions, Inc.Inventors: Tom Holman, Jeff Welch, Howard Root

Publication number: 20120215255Abstract: A PFO closing device for bringing the septum primum and the septum secundum into contact with each other and joining them together includes a clamping mechanism and energy supplying device. The clamping mechanism includes a needle part for puncturing the septum primum, and a clamping member for cooperating with the needle part in clamping therebetween tissue of the septum primum and the septum secundum. The energy supplying device supplies energy for joining the tissues clamped by the needle part and the clamping member. The clamping mechanism is mounted in a catheter so as to be protrudable from and retractable into the catheter.Type: ApplicationFiled: April 30, 2012Publication date: August 23, 2012Applicant: TERUMO KABUSHIKI KAISHAInventor: Yukitoshi KATO

Patent number: 8226669Abstract: The invention concerns a device comprising: a packaging box for the flexible material part, dimensioned to hold said part flat; folding means for folding said part without direct handling; and a reception tube for receiving said folded flexible material part. The invention is characterized in that the folding means comprise; a traction suture connected to the flexible material part, which passes through the tube, and, walls forming a funnel whereof the base emerges proximate to the opening of the tube through which the flexible material part is designed to be inserted into said tube, said funnel being designed, when a traction is exerted on the traction suture, to gradually fold down the zones of the part located laterally relative to the tube towards the zone of the part located opposite the opening of said tube, to enable the part to be inserted into the tube.Type: GrantFiled: May 21, 2010Date of Patent: July 24, 2012Assignee: Sofradim ProductionsInventors: Bernard Detruit, Michel Therin, Pierre Bailly

Patent number: RE44297Abstract: A tool (101) is provided for inserting and mating two plug members (2, 3) of a sealing device (1) for closing a wound in the wall of a vessel by placing the distal plug member (2) of the sealing device inside the vessel and the proximal plug member (3) on the outside of the vessel. The distal plug member is provided with an elongated retracting means (6) extending from the distal plug member. The tool comprises a gear mechanism (32) coupled to the retracting means for converting a movement of the tool in a proximal direction away from the wound (22), when the distal plug member is anchored in the vessel (20), to a pushing movement for moving the proximal plug member in a direction towards the distal plug member in response to a stretching force in the retracting means.Type: GrantFiled: June 18, 1999Date of Patent: June 11, 2013Assignee: Radi Medical Systems ABInventors: Dan â„«kerfeldt, Per Egnelov, Fredrik Preinitz
