    摘要： A surgical dilator extractor is introduced into the abdominal cavity through a trocar cannula and expanded, forming a tissue receiving space, at the distal end. The tissue that is to be extracted is then suctioned to the dilator. The tissue is then removed from the cavity by the surgeon applying a force onto the dilator extractor that insures the elongation of the tissue and temporarily dilates the entry wound to the extent necessary for the tissue to be removed. Alternative embodiments of the surgical dilator extractor and related instrument tool sets and methods for the use thereof also are disclosed.

    摘要： Surgical instrumentation and methods for performing a bypass procedure in a digestive system incorporate laparoscopic techniques to minimize surgical trauma to the patient. The instrumentation includes, an outer guide member dimensioned for insertion and passage through an esophagus of a patient and defining an opening therein extending at least along a portion of the length of the outer guide member, an elongate anvil delivery member at least partially disposed within the opening of the outer guide member and being adapted for longitudinal movement within the outer guide member between an initial position and an actuated position and an anvil operatively engageable with the delivery member. The anvil includes an anvil rod defining a longitudinal axis and an anvil head connected to the anvil rod. The anvil head is at least partially disposed within the opening of the outer guide member when in the initial position of the delivery member and is fully exposed from the distal end of the outer guide member upon movement of the delivery member to the actuated position.

    摘要： An endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes a frame portion, an elongated portion extending from the frame portion, and an articulating fastener applying assembly associated with a distal end of the elongated portion. The fastener applying assembly includes a base portion, a staple cartridge housing, and an anvil member which has a forming surface thereon against which surgical fasteners are driven as they are ejected from the cartridge housing. A first mechanism is provided for effectuating the rotation of the fastener applying assembly about an axis defined by the body portion, a second mechanism is provided for effectuating the articulation of the fastener applying assembly, and a third mechanism is provided for independently rotating the cartridge housing and anvil member relative to a longitudinal axis defined by the base position to increase the range of operability of the apparatus.

    摘要： An arterial closure device for use following coronary catherization procedures to close arterial access openings through the arterial wall while permitting post operative flow through the artery includes a housing having proximal and distal ends, and defining a longitudinal axis, first and second arterial tissue everting members mounted adjacent the distal end of the housing and first and second jaw members mounted adjacent the first and second tissue engaging members. The first and second arterial tissue everting members are dimensioned for at least partial positioning within the arterial access opening in the arterial wall and are deployable in at least a radial outward direction relative to the longitudinal axis of the housing to engage respective opposed arterial tissue portions on opposed sides of the opening and move the tissue arterial portions to an everted condition thereof. The first and second jaw members are adapted for relative movement between an open position to facilitate positioning about the arterial tissue portions in the everted condition and a closed position to at least partially draw the arterial tissue portions together to an at least partial approximated condition. An electrode is associated with at least one of the first and second jaw members and arranged to contact the respective arterial tissue portions. The electrode is adapted to be connected to a radiofrequency energy source whereby energy is transmitted through the electrode to thermally fuse the arterial tissue positions between the first and second jaw members to substantially close the opening. Preferably, an electrode is associated with each of the first and second jaw members. Each electrode nay be configured as a bipolar electrode.

    摘要： The endovascular graft disclosed includes a main tubular body having a first end portion and an exterior surface. The first end portion has a flanged end disposed on exterior surface and extending radially thereabout, for engaging blood vessel walls. The graft may be made from a surgically implantible material. The graft has a second end portion of the main body that can either be a continuation of the main body or split into two tubular legs. The two tubular legs, each define a bore. The bore of the main body is in communication with the bores of the legs.A method of installing the endovascular graft includes installing the graft intraluminially to the operative site using a catheter having a balloon portion. The graft is positioned to extend through a damaged portion of a blood vessel. The balloon portion is positioned within a bore defined by the graft proximal to a first end portion, the first end portion having a flanged end. The balloon is expanded such that the flanged end expands into a blood vessel forming a raised portion on an exterior surface of the blood vessel. Finally, surgical clips are atraumatically applied to the raised portion compressing vessel tissue about the flanged end to capture the graft within the blood vessel.
