Retrieval device

An endoscopic device for retrieving an object from within a human body, the device comprising:

• a support assembly comprising a base and an elongated tubular member;
• a transmitting assembly comprising a handle movable relative to the base, and a link having a first end fixed to the handle and a second end remote from the base, the link extending through at least a portion of the tubular member;
• a wire defining a loop portion and two leg portions, wherein each leg portion is secured to the second end of the link by a first connection, and the two leg portions are secured to each other by a second connection;
• and
• a net element having a distal portion secured to the loop portion and a proximal portion secured relative to the second connection by a tether;
• wherein the loop portion is movable between an expanded position outside the tubular member and a collapsed position within the tubular member by action of the handle relative to the base.
