ABSTRACT:
A surgical device20for attaching staples40to a portion of a body comprising an anvil23; a smart memory material (SMM)50, 75capable of going from one physical state to another physical state; a supply of staples in communication with the smart memory material and placed near the anvil; and an activating apparatus21which is in communication with the smart memory material and which can cause the change in the physical state of the smart memory material, which change in state causes the movement of the staples against the anvil thereby securing the staples40to the desired body portion. The device utilizes a source of electricity which when activated causes the SMM to expand in volume thereby moving an individual staple from the supply of staples. The device may also contain a surgical knife62to cut a body portion wherein a SMM is in communication with the knife whereby when the SMM expands it engages the knife causing the knife to cut the desired body portion.
