Abstract
An endoscopic suturing device is provided for manipulating a suture to form a stitch through a tissue within a body cavity. The suturing device comprises a needle with a shaft, a pointed end located at the distal end of the suturing device, a receptacle formed proximally to the pointed end, and a latch for opening and closing the receptacle. The latch is biased to the open position. A tubular sheath is provided which is concentric with the needle shaft, the needle shaft being frictionally slidable within the tubular shaft. The suture is clamped by the device by inserting the suture into the receptacle and sliding the tubular sheath over the latch, thereby closing the receptacle. The suture can then be released by sliding the tubular sheath to uncover the latch, thereby opening the receptacle.
