Patent number: 5921997Abstract: A clip, 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: September 19, 1997Date of Patent: July 13, 1999Assignee: Ethicon Endo-Surgery, Inc.Inventors: Mark Fogelberg, J. David Hughett, C. Kerwin Braddock, Michael E. Boehm, David Stefanchik, Michael A. Murray

Patent number: 5562701Abstract: A jaw assembly is provided with a pair of jaws which are closed with a flexible, tension member that is pulled by the operator of the instrument. In a preferred embodiment, one of the jaws is pivotally mounted in a slot to the other jaw. A cord, having a loop configuration, is attached to the pivoting jaw and can be pulled to pivot the jaw closed. A second cord can be provided to initially hold the proximal end of the pivoting jaw away from the other jaw until the distal ends of the jaws are closer together. In another embodiment, jaws can be closed in a parallel orientation by rotating two pulleys with threaded shafts engaged with the jaws.Type: GrantFiled: May 9, 1995Date of Patent: October 8, 1996Assignee: Ethicon Endo-Surgery, Inc.Inventors: Thomas W. Huitema, Warren P. Williamson, Matthew Otten, Kenneth S. Wales, Mark Fogelberg, James H. Chambers

Patent number: 5405344Abstract: An articulable assembly is provided for an endoscopic instrument along with a surgical fastener track therefor. The assembly includes a distal end portion for supporting an end effector to effect tissue manipulation while carrying out a surgical procedure within a body cavity. The assembly includes an articulable joint connecting an elongate support housing with the distal end portion. The joint includes a hollow socket and a convex member that is received in the socket. The convex member defines a passageway for accommodating an actuator extending from the housing through the joint to actuate the end effector. An operator is provided on the housing and extends to the socket or convex member for moving the distal end portion into and out of alignment with the housing. A flexible track is provided for guiding fasteners through the joint.Type: GrantFiled: September 30, 1993Date of Patent: April 11, 1995Assignee: Ethicon, Inc.Inventors: Warren P. Williamson, Steven Burnett, Jack E. Smith, Mark Fogelberg, E. David Allen
