摘要:
An endo-vascular fastener applicator is provided for endo-luminal fastening of a prosthetic to a vessel with a fastener. The applicator includes a tubular body that is configured for positioning within a vessel, an expandable portion disposed adjacent the distal end of the tubular body and deployed to support a prosthetic in contact with an inner surface of a vessel, and a drive assembly for advancing a fastener into the prosthetic. A delivery tube may be included that is disposed for movement within the tubular body, and which defines a channel for movement of the drive assembly there within. The delivery tube may include an applicator head. The applicator head may include an injection mount that is disposed for movement relative to a prosthetic.

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.

An apparatus for facilitating closure of an opening in a blood vessel, includes a closure instrument having an elongated member defining a longitudinal axis and proximal and distal ends. The elongated member has a vacuum lumen extending at least a portion of the length thereof for conveying a vacuum and terminating in a vacuum port adjacent the distal end of the elongated member. The distal end of the elongated member is dimensioned to be positioned proximal a vessel opening in a blood vessel whereby vessel edge portions defining the vessel opening are at least drawn toward the vacuum port in response to a vacuum conveyed through the vacuum lumen. At least one surgical clip is mounted adjacent the distal end of the elongated member and is adapted to be formed to an at least partially formed condition thereof. The one clip is positioned with respect to the vacuum port to engage the vessel edge portions drawn toward the vacuum port upon movement of the one clip to the formed condition thereof to generally approximate the vessel edge portions to at least partially close the vessel opening. A method for facilitating closure of an opening in a blood vessel is also disclosed.

A self contained gas powered 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 cartridge assembly mounted to a distal end of the elongated portion. An anvil member is operatively associated with the articulating cartridge assembly and has a forming surface, thereon against which surgical fasteners are driven as they are ejected from the cartridge assembly. A collar which is provided in the elongated portion translates longitudinally to draw a cable which operates to move the anvil member relative to the cartridge assembly, thereby clamping body tissue to be fastened. A self contained pneumatic system is associated with the frame portion and is actuable to eject the surgical fasteners from the cartridge assembly. A linkage mechanism is also provided for effectuating the articulation of the cartridge assembly to increase the range of operability of the apparatus.

摘要:
A self contained gas powered endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes an anvil member and a surgical fastener cartridge member mounted to the distal end of an elongated endoscopic portion. A tubular collar of the endoscopic portion moves distally to engage the anvil member and bias the anvil member and the cartridge member into cooperative alignment, thereby clamping body tissue to be fastened between the anvil member and the cartridge member. A self contained pneumatic system is disposed in the surgical apparatus and is actuable to eject and/or form the surgical fasteners in the clamped body tissue. The apparatus further comprises a locking mechanism for preventing firing of the instrument after it has been fired a predetermined number of times. A counter for displaying the number of times the apparatus has been fired may be provided. A firing interlock is also shown which prevents accidental actuation of the firing trigger. A clamping interlock is shown which prevents approximation of the jaws when the jaws are either misaligned or improperly inserted into the instrument.

A surgical stapler for placing lateral lines of staples and making an incision, all through an endoscopic tube, includes an anvil member which is mounted to the distal end of an elongated housing. A tubular collar disposed around the arm of the anvil member is movable to a distal position to bias the anvil member and a cartridge assembly into cooperative alignment, thereby clamping body tissue to be fastened between the anvil member and cartridge assembly.
