ABSTRACT:
The present invention is a suture device generally intended for use in puncture wounds of a body cavity. The suture device can be inserted through the tissue layer into the body cavity and extend needles attached to a common suture line, under endoscopic vision, for engagement with the internal side of the tissue layer. The needles are deployed using a straight spring that deforms outwardly from the shaft of the suture device when a force is applied to the spring. Because of the inherent characteristics of the spring, it bends perpendicular to the shaft of the suture device and the removably attached needle is moved outwardly while staying generally parallel to the shaft of the suture device. Once the force is removed on the spring, the spring returns to its original position close to the body of the shaft.
