Patent number: 5681330Abstract: A clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. If satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.Type: GrantFiled: October 4, 1996Date of Patent: October 28, 1997Assignee: Ethicon Endo-Surgery, Inc.Inventors: J.

Patent number: 5676675Abstract: A laparo-suture needle and method for use thereof. A medical suturing instrument employs an outer, hollow shaft having a laterally-disposed, elongate handle at a proximal end and an elongate, inner shaft disposed within the outer shaft. The inner shaft has a cutting edge at the distal end and extends out of the outer shaft at the proximal end, terminating in a spring-loaded push button. A lateral notch is formed in the inner shaft proximal of the cutting edge. The spring forces the inner shaft rearwardly so as to pull the notch within the outer shaft. By gripping the handle and placing pressure on the push button, the inner shaft is moved forward so as to expose the notch. A suture may then be placed in the notch so that the instrument grips the suture between the outer shaft and the inner shaft when the push button is released.Type: GrantFiled: April 28, 1994Date of Patent: October 14, 1997Inventor: O. Drew Grice

Patent number: 5676689Abstract: A system for sealing a percutaneous puncture in a blood vessel in a living being and method of use thereof. The system includes a hemostatic closure, a blood vessel locator device for determining the position of the blood vessel via the percutaneous puncture, and a deployment instrument for deploying the closure within the puncture to seal the puncture. The vessel locator includes means for enabling blood from the vessel to flow therethrough so that the position of the vessel can be rapidly determined. Once the vessel has been located the deployment instrument, which includes a tubular carrier storing the closure, is extend into the puncture to deploy the closure. The closure basically comprises a radiopaque rigid anchor for location within the blood vessel, a compressed collagen plug for location within the puncture tract leading to the vessel, and a thin filament connecting the two in a pulley-like arrangement.Type: GrantFiled: February 28, 1996Date of Patent: October 14, 1997Assignee: Kensey Nash CorporationInventors: Kenneth Kensey, John Nash, Douglas Evans

Patent number: 5667513Abstract: A soft tissue anchor delivery apparatus includes a gripping device having fingers at the distal end and configured such that they can hold a soft tissue anchor about the head portion of the anchor. An actuating tube slides over the gripper and the fingers, thus holding the fingers and the contained soft tissue anchor within the bore of the actuating tube. A pushrod is placed within the bore of the gripper. The pushrod has a countersunk head that is shaped such that it is a close fit for the head of the soft tissue anchor. The pushrod is connected to a tube having a bore so that the actuating pin of the soft tissue anchor can be pushed down into the head of the anchor. The pushrod is spring loaded so as to allow the pushrod to be driven distally upon retraction of the actuating tube, thus driving the anchor free of the deployed fingers and hence of the entire delivery system.Type: GrantFiled: June 7, 1995Date of Patent: September 16, 1997Assignee: Smith & Nephew Dyonics Inc.Inventors: Paul A. Torrie, Graham Smith

Patent number: 5667526Abstract: A surgical clamp has pivoting jaws with undulating arrays of teeth that are interdigitating and offset with relation to each other. This clamp structure assures a firm, non-slipping grip in the presence of blood and body fluids during surgery. The inner surfaces of the jaws are concave to allow the clamp to grasp more tissue or organ that would be possible with flat inner surfaces. Laparoscopic and open surgery embodiments are included. An alternative to the embodiment is a clamp having openings through which tissue or an organ can protrude to allow an even greater amount of tissue or organ to be grasped.Type: GrantFiled: September 7, 1995Date of Patent: September 16, 1997Inventor: John M.

Patent number: 5665111Abstract: A surgical method and tools for anchoring a suture to bone is disclosed. The method includes forming an opening through a top surface of the bone, positioning a suture within the opening and crimping a region of the top surface of the bone surrounding the opening to anchor the suture within the opening. The tools used with the disclosed surgical method include a punch, a broach, a guide and a swage. The punch and the broach are used to create a uniform diameter opening in the bone by compressing bone material. The guide is used to position a suture, preferably having a shoulder, in the opening. Finally, the suture is used to crimp the region of the top surface of the bone surrounding the opening.Type: GrantFiled: January 22, 1996Date of Patent: September 9, 1997Assignee: RayMedica, Inc.Inventors: Charles D.
