Abstract
An endoscopic device for retrieving an object from within a human body is disclosed. The device includes a support assembly, a transmitting assembly, a wire, and a net element. The support assembly has a base and a tubular member. The transmitting assembly includes a handle and a motion transmitting link fixed to the handle and extending through at least a portion of the tubular member. The wire defines a loop portion and two leg portions. A proximal end of each leg portion is secured to the link by a first connection and the two leg portions are secured to each other by at least a second connection distal from the first connection. The net element has a distal portion secured to the loop portion and a proximal portion secured relative to the leg portions. The loop portion is movable between an expanded position and a collapsed position.
