    摘要： A surgical fastener configured to close an opening in tissue is provided. The surgical fastener includes a base defining a central axis at least one pair of legs extending from the base. Each of the legs includes a base portion and a tissue engaging portion. When in a first position, each of the tissue engaging portions is arranged to define an insertion direction and when in a second position, each of the tissue engaging portions extends inward towards the central axis. The surgical fastener is at least partially formed from a shape memory material including a combination of Polydioxanone and Poly(L-lactide) or a combination of Trimethylene Carbonate and Poly(L-lactide). The pair of legs are configured to move from the first position to the second position upon activation of the shape memory material.

    摘要： A surgical fastener applying apparatus includes an anvil section and a cartridge section, where the cartridge section and the anvil section are movable from an unclamped position to a clamped position to clamp tissue therebetween. The cartridge section has a plurality of retention slots. A plurality of first surgical fasteners and a plurality of second surgical fasteners are disposed within a corresponding retention slot. The plurality of first surgical fasteners has a first backspan with a first configuration and the plurality of second surgical fasteners has a second backspan with a second configuration. The first configuration is different from the second configuration. In addition, when the first configuration applies a first compressive force to tissue upon formation of the plurality of first surgical fasteners and the second configuration applies a second compressive force to tissue upon formation of the plurality of second surgical fasteners, the second compressive force is different from the first compressive force.

    摘要： The present disclosure is directed to staple-gap adjustment members for use in surgical stapling apparatus and methods. A gap adjustment member includes one or more bearing portions sharing a common rotational axis and one or more cam surface portions having a periphery with at least two different points along the periphery, with each point along the periphery having a different radius from the rotational axis. The one or more cam surface portions can have a central axis parallel to and spaced a distance from the rotational axis of the one or more bearing portions.

    摘要： An electrosurgical stapling apparatus is provided which uses thermogenic energy as well as surgical fasteners or staples for strengthening tissue, providing hemostasis, tissue joining or welding. The thermogenic energy also strengthens tissue in proximity to a staple line and knife cut line and provides hemostasis along the staple and cut lines formed by the staples and a knife blade during surgical stapling. The use of thermogenic energy provides short-term hemostasis and sealing, and reduces or prevents staple line and cut line bleeding, while the stapling features provide short and long-term tissue strength and hemostasis. The stapling apparatus further substantially reduces or prevents knife cut line bleeding by energizing a knife blade for cauterizing tissue while it is being cut. In one embodiment, energy is applied to the anvil to energize the staples as they make contact with the anvil.

    摘要： A biopsy system for retrieving biopsy tissue samples from different regions of the body is disclosed. The biopsy system includes a single use loading unit having a trocar assembly and a knife assembly. A trocar driver is operably connected to the trocar assembly and is actuable to move a trocar between retracted and advanced positions. The trocar driver is disengaged from the trocar assembly prior to firing the trocar into a target tissue mass to reduce drag on the trocar during firing. A knife driver is operably connected to the knife assembly such that when actuated, a knife is both rotatably and axially advanced about the trocar.
