Abstract: Palm-size staplers for surgical procedures are proposed. The staplers include cartridge and slider assemblies with the cartridge assembly containing staples. As the slider assembly advances step-wise incrementally it provides a staple ejection force causing ejection of staples. Optionally, a blade element may be included for cutting. An anvil member is operable in closed and open positions with respect to the cartridge assembly. When in a closed position, the anvil member holds a portion of tissue against the cartridge assembly, ejected staples passing through the held tissue. Actuation of the staplers is effected by a lever member. A locking mechanism, when in its locked position, holds the anvil member adjacent to the cartridge assembly allowing closure of the staple to occur. The devices are intended for one hand use.

Abstract: Apparatus for intratubular intussusception and anastomosis of a hollow organ portion including a cylindrical enclosure, coaxial intratubular intussusception device, for intussusception and clamping means. The apparatus also includes an intratubular anastomosis apparatus for joining organ portions after intussusception thereof with an anastomosis ring and crimping support element. The ring is formed of a shape memory alloy wire, for crimping adjacent organ portions against the crimping support element so as to cause anastomosis therebetween. The ring assumes a plastic or malleable state, at a lower temperature and an elastic state at a higher temperature. The apparatus further includes the crimping support element for intratubular insertion so as to provide a support for crimping the organ portions against the support element.

Abstract: The present invention, discloses an anastomosis clip applicator device for applying a surgical clip, formed at least partly of a shape memory alloy, to press together adjacent wall portions of adjacent hollow organ portions so as to effect anastomosis therebetween. The applicator device includes: gripping apparatus for gripping a surgical clip, a release mechanism, associated with the gripping apparatus, and tissue cutting apparatus, operatively associated with the gripping apparatus. There is also apparatus for activating the gripping apparatus, the release mechanism and the cutting apparatus, so as to introduce and apply the surgical clip into adjacent hollow organ portions, such that the surgical clip compresses together the adjacent walls of the hollow organ portions, and thereafter causes the cutting apparatus to perforate the adjacent pressed together organ walls to provide patency through the joined portions of the hollow organ.

Abstract: An intratubular anastomosis apparatus for joining organ portions of a hollow organ after intussusception which includes an anastomosis ring, and a crimping support element. The anastomosis ring includes a length of a wire formed of a shape memory alloy for crimping adjacent organ portions against the crimping support element so as to cause anastomosis. The anastomosis ring and the shape memory alloy assumes a plastic state, when at a first, lower temperature and an elastic state, when reaching at least a second, higher temperature. The crimping support element provides a support for crimping the organ portions against the support element. Using the anastomosis ring and crimping support element of the present invention reduces the risk of leakage and no staples or sutures remain within the anastomosed organ portion.
