Abstract
An improved device and method for suturing penetrations and incisions through tissue into a body cavity. The device should find particular use in laparoscopic and other types of minimally invasive surgical procedures. A device according to the invention includes a shaft and an inverted needle joined to the shaft. Two ends of a length of suture material are attached at or near a sharpened proximal tip on the needle. The device may include a movable shield that is slidable to alternately cover and expose the sharpened tip of the needle. This shield may include a blunt distal end and an inclined proximal surface to assist the surgeon in guiding the hook into and out of the body cavity. The device may be provided with a visual and tactile indicator on one side of the device to assist the user in threading and removing the suture material into and out of a selected side of the hook.
