摘要： Valve prosthesis systems and methods/systems for placement of such valve prostheses are provided that facilitate efficient, reliable and minimally invasive delivery modalities. The placement systems and methods permit remote manipulation and positioning of the valve prosthesis such that desirable placement relative to anatomical structures, e.g., the heart annulus, may be achieved. The valve prosthesis includes a resilient ring, a plurality of leaflet membranes mounted with respect to the resilient ring, and a plurality of positioning elements movably mounted with respect to the flexible ring. The delivery system includes a first elongate element that terminates at the valve prosthesis and is manipulable by an operator to remotely rotate the positioning elements relative to the flexible ring. A second elongate element terminates at the valve prosthesis and is manipulable by an operator to remotely advance the valve prosthesis downward into an anatomical annulus. The second elongate element may be manipulated to remotely advance the valve prosthesis into the anatomical annulus to assume a position for supporting post-implantation function of the valve prosthesis in situ. The first elongate element may be further manipulated to remotely rotate the positioning element relative to the flexible ring to cause the positioning element to engage tissue associated with the anatomical annulus and to thereby maintain the post-implantation position of the valve prosthesis in situ. Methods for valve prosthesis deployment are also provided.

摘要： A method and apparatus for closing a punctured blood vessel is described. The method includes providing a clip applier adapted to apply one or more surgical clips to at least a portion of the exterior of a blood vessel in order to close a puncture wound therein. In a preferred embodiment, the clip applier is guided to the puncture by a guide wire and one or more surgical clips are applied to close the puncture wound.

摘要： A tagging device for marking the location of lesions within the body prior to a surgical procedure such as excision or biopsy. The device includes an elongated tube having one end supported on a housing and a second end extending distally therefrom. An anchor is positioned within the distal end of the elongated tube and has an elongated member extending proximally therefrom. An actuation assembly including a plunger is movable within the tube to engage and push the anchor from the distal end of the tube. The anchor and the actuation assembly are positioned and configured such that the anchor is pivoted from a position parallel to the longitudinal axis of the tube to a position perpendicular to the longitudinal axis of the tube as it as being pushed from the tube.

摘要： A surgical instrument for cutting tissue, which includes a housing, a cutting element movable between a retracted position disposed substantially within the housing and a deployed position extending outwardly from the housing, a guide member configured and dimensioned to direct orientation of the cutting element, operatively connected to the housing and defining a longitudinal axis, the guide member movable from a first orientation wherein the longitudinal axis of the guide member is aligned with a longitudinal axis of the housing to a second orientation wherein the longitudinal axis of the guide member is oriented at a predetermined angle relative to the longitudinal axis of the housing. A method for surgically removing tissue is also provided and includes the steps of inserting an instrument into an incision formed at the operative site, deploying a blade guide at an angle relative to a longitudinal axis of the instrument, deploying a cutting element from a retracted position to an exposed position such that the cutting element is guided by the blade guide, moving the cutting element through a predetermined path such that a section of tissue is separated from the surrounding tissue, and removing the cut tissue from the surrounding tissue.
