    摘要： A surgical stapler for applying staples to compressed tissue comprising: a handle portion having surfaces adapted to be manually grasped by a surgeon; a cartridge retention portion and an anvil retention portion, means for mounting said cartridge retention portion and said anvil retention portion for relative movement between a closed position in which said cartridge retention portion and said anvil retention portion are in closely spaced relationship for clamping tissue to be stapled therebetween and an open position in which said cartridge retention portion and said anvil retention portion are spaced farther from each other than in the closed position, an anvil having a plurality of specially shaped surfaces, said cartridge retention portion having a staple housing for enclosing six rows of staples in substantially parallel, linear rows having proximal and distal ends, said six rows being spaced laterally across the staple housing such that any line drawn laterally across the staple line crosses at least three staples, staple drivers adjacent staples, and a plurality of pushers each having camming surfaces, said staple housing being elongate to define a longitudinal axis, said staple housing having a plurality of longitudinally extending pusher slots adapted to receive said pushers to afford movement of said pushers in a firing direction between pre-fired and fired positions, and a plurality of driver channels for receiving said staple drivers to afford movement of said staple drivers in a staple driving direction between pre-eject and ejected positions; and each of said staple drivers having a cam follower surface for engaging the camming surface of a pusher to move the staple driver from the pre-eject toward the ejected position to substantially sequentially eject the staples in a row from the staple housing and press the ejected staples against the specially shaped surfaces of the anvil to engage, form and close staples in tissue clamped between the staple housing and the anvil.

    摘要： It is a purpose to provide a medicinal-liquid injection apparatus in which a needle-like tubular member is smoothly movable in a lumen without damaging an inner circumferential surface of the lumen. It includes that the needle-like tubular member having an acuminate needle portion as a free end portion thereof, in which a medicinal liquid can flow, is inserted in the lumen of a tubular main body insertable in a body of a living being, and a protection member having a flexible portion provided in a state such that the protection member is movable together with the needle-like tubular member and such that the flexible portion is interposed between an inner circumferential surface of the lumen and a tip of the needle portion of the needle-like tubular member.

    摘要： A packaging device for a trocar assembly includes a housing member having a first retaining member adapted for selective retention of a trocar assembly component relative to the housing member along a component longitudinal axis. The housing member further includes a shield member remote from the first retaining member. The shield member lies in a shield longitudinal axis which is substantially perpendicular to the component longitudinal axis. The housing member is substantially open adjacent the shield member along the component longitudinal axis.

    摘要： A single shot trocar-needle insertion insrument is configured for repeated use. The repeated use trocar-needle insertion gun (RUTI) (200, 300) operates in association with a loading tool (1000, 1100, 1200, 1300), which for reload, is coupled with the RUTI via a loading opening (150, 350). The loading tool reloads the RUTI without requiring disassembly of the operative mechanism (1). The loading opening is provided ready open (150) or closed (350) but openable in situ, where the insertion is administered. It is possible to implement a RUTI by entering a loading opening in an existing single shot trocar-needel insertion instrument (SSTI). After reload with the loading tool, a catch is operated to retain the RUTI in the loaded state. A trocar-needle (10) and the front portion (III) of the RUTI are then attached, whereby the RUTI is returned to operative condition.

    摘要： Methods and apparatus for making an anastomotic connection between a first conduit (10) and a second conduit (20). A connector structure (200) having a first end portion and a second end portion is positioned about a balloon catheter (300), which when pressurized, expands to a significant extent at the distal end thereof. The balloon (300) enlarges the connector structure (200) when positioned at the distal end portion of the balloon (300) to create the anastomosis, and at the same time reduces the axial length of the connector (200), thereby compressing the first conduit (10) to the second conduit (20), creating a hemodynamic seal and a firm attachment of the two conduits (10, 20). After enlargement, the connector structure (200) remains in place and adds structure to the anastomosis. During introduction, the second end portion of the connector is covered by a nosecone assembly (404) to prevent trauma to the second conduit (20) while the apparatus is being introduced. The nosecone assembly (404) has a flexible structure which may change configuration to expose the second set of members (218) after insertion into the second conduit (20) and to allow removal of the nosecone (404) after deployment.
