Abstract
Surgical needles are fabricated from a shape memory alloy. The alloy has a low temperature state, in which the needle is formable into an elongated shape to pass through an elongated tube, and a high temperature state, in which the needle forms an arc. The needle is particularly adapted for use in endoscopic surgery. A needle that has a remembered curved shape is straightened and passed to a surgical site through a cannula. It is then returned to its curved shape by heating it at the surgical site. After use, it is withdrawn through the cannula.
