Abstract

A surgical device for suturing a wound in the tissue of a patient. The device includes a longtiudinal sheath having a proximal end and a distal end, a recess formed in the wall of the sheath toward the distal end, a needle constructed of a spring-like material, a retaining mechanism that constrains the needle in a retracted position by deforming the needle, and an actuator at the proximal end of the sheath that releases the restraining mechanism to allow the needle to assume an undeformed condition and move to an exposed position. The needle is movable from the retracted position, where the needle is withdrawn into the recess, to the exposed position, where the needle extends from the recess and points generally in the direction of the proximal end of the device.
