摘要

2091361 9204869 PCTABS00011 A ligator assembly (200) comprising a hollow, two-piece, bullet-shaped cases (202) dimensioned to be inserted in and through a body member, a pair of suture needles (244) carried by the case, and a suture (250) affixed to the needles. The case is provided with a pair of guide tubes (242) for retaining the needles and guiding them out through a substantially transverse slot (230) at the end of the case. A drive mechanism is also provided for remotely driving the needles (272) longitudinally out of the case through the slot. The case is selectively connectable to an elongated tubular operator for placement of the ligator assembly. Apparatus for effecting an anastomosis comprises female and male connector components (300, 28') usable with an operator, an inflatable anvil assembly (23'), and a connector actuator and which include mutually facing clamping surfaces for clamping generally annular tissue portions of the first and second body members together.
