US Patent:

20060178682, Aug 10, 2006

Filed:

Feb 4, 2005

Appl. No.:

11/051892

Inventors:

Raimar Boehlke - Excelsior MN, US

International Classification:

A61B 17/04

US Classification:

606148000

Abstract:

The present invention is directed to methods and apparatus for cutting filaments percutaneously. The methods and systems may be used in conjunction with sealing a puncture percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug. The present invention provides for safe filament cutting below the skin and may reduce the risk of cutting the filament distal of any knots.

Abstract:

A vascular closure delivery system for closing a tissue wall opening is provided. In one embodiment, the vascular closure delivery system comprises a suturing apparatus and suture delivery unit and a suture knot system. The suturing apparatus and suture delivery unit comprises at least one tube, at least one leg, a tensioning device, a pusher, a suturing apparatus, and an actuator. The at least one tube is configured to house the pusher and the suturing apparatus and has an expulsion end. The at least one leg has a first end and a second and is coupled to the at least one tube proximate the first end of the leg. The tensioning device is coupled to the at least one leg proximate the second end of the leg. The pusher has a suturing apparatus engaging end and is slidably disposed within the tube. The suturing apparatus has a sharp end and an opposite end and is slidably disposed within the tube. A suture is associated with the suturing apparatus. The actuator is operatively associated with the pusher. When the at least one leg is in an open position, the tensioning device exerts tension on the leg such that the leg is movably suspended and can move with respect to the tensioning device, and the pusher and suturing apparatus are in an delivery configuration for delivery of the suturing apparatus to the internal tissue wall. Further, actuation of the actuator moves the pusher towards the expulsion end of the tube such that the suturing apparatus engaging end of the pusher engages the suturing apparatus and expels the suturing apparatus from the tube. The suture knot system comprises a shaft, an inner tubular member, and an inner rod. The shaft has a proximal end and a distal end. The inner tubular member has a proximal end and a distal end and is provided within the shaft. The inner tubular member is radially translatable with respect to the shaft. The inner rod has a proximal end and a distal end and is provided within the inner tubular member. The inner rod is slidably coupled to the inner tubular member and is axially translatable within the inner tubular member.

Abstract:

A knot pusher device for deploying a plurality of pretied knots to a surgical site is provided. In one embodiment, the knot pusher device comprises a shaft, an inner tubular member, and an inner rod, each having a proximal end and a distal end. The inner tubular member is provided within the shaft and is radially translatable with respect to the shaft. The inner rod is provided within the inner tubular member and is slidably coupled to the inner tubular member and is axially translatable with respect thereto.
