A collapsible anvil assembly and applicator instrument for use with a surgical stapler. The collapsible anvil assembly includes an anvil shaft and a plurality of anvil segments, having staple clinching buckets thereon, flexibly affixed to the anvil shaft which are movable between a collapsed or radially inwardly deflected condition and an expanded or radially outwardly deflected condition. Immobilizing means in the form of an axially slidable locking ring is provided to fix and maintain the anvil segments in the expanded condition. Mounting element are also provided for subsequent detachable mounting of the anvil assembly on a surgical stapler. The collapsible anvil assembly may also include a suction purse stringing device which attracts and holds a surrounding tissue section within the anvil segments. Additionally, an axially slidable tissue holding ring or snap cap is provided to lock the held tissue section within the anvil segments.

Collapsible anvil assembly and applicator instrument

A surgical instrument for carrying and attaching separate components of a compression anastomosis device to the end of tissue of a tubular hollow organ, which includes an elongated housing having a proximal end and a distal end; first and second compression anastomosis device components; a supporting member operatively associated with the distal end of the elongated housing, for supporting the first and second compression anastomosis device components; and assembling structure associated with the supporting member and operable from the proximal end of the elongated housing, for assembling the first and second compression anastomosis device components within tubular body tissue.

Apparatus and method for performing compressional anastomoses

An apparatus for suturing body tissue is provided having an elongated housing, first and second jaws pivotably mounted to the distal portion of elongated housing, and first and second needles movable with respect to the first and second jaws. A first actuating mechanism is operatively associated with the first and second jaws such that actuation moves the jaws from the first position to a second position. A second actuating mechanism is operatively associated with the first and second needles wherein actuation advances the first and second needles into body tissue. Each of the jaws has a recess for receiving body tissue and a ferrule attached to each end of the suture such that advancement of the needles engages the ferrule to pull the ferrule and suture through the body tissue when the needle is retracted.

Apparaus and method for suturing body tissue

Apparatus and method for forming a compression anastomosis of a hollow organ. The apparatus comprising a first collapsible member movable between an expanded configuration and a collapsed configuration, the first collapsible member having a longitudinal bore defined by an inner surface, a first mating member, locking structure disposed on the first collapsible member for locking the first collapsible member with the first mating member, a second collapsible member movable between an expanded configuration and a collapsed configuration, the second collapsible member having a longitudinal bore defined by an inner surface, a second mating member, locking structure disposed on the second collapsible member for locking the second collapsible member with the second mating member, and the first member adapted to interlock with the second member. A tissue retaining device is also provided which comprises a mating member having a receiving portion formed thereon, said receiving portion having an inner surface and securing structure comprising a ring having an outer surface dimensioned and configured for insertion into said receiving surface to compress tissue between said outer surface of said ring and an inner surface of said mating member receiving portion.
