    摘要： A vascular closure device used in closing openings in vessel walls while permitting post-operative flow through the vessel includes a housing, at least two tissue engaging members, and at least two jaw members. The tissue engaging members engage tissue portions on opposite sides of the vessel opening and move tissue to a desired, predetermined position. The jaw members are adapted, in an open position, for positioning about the tissue portions in the predetermined position, and in a closed position, to at least partially draw the tissue together to an at least partially approximated condition. An attachment member is associated with at least one of the jaw members and arranged to contact the tissue. In one embodiment, the attachment member is adapted for connection to an energy source whereby energy is transmitted through the attachment member to thermally fuse the tissue engaged by the jaw members to substantially close the opening.

    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 radio frequency 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.
