Bags designed for retrieval of tissues and/or small organs during laparoscopic procedures. These devices typically consist of a disposable folded bag made of plastic (e.g., polyethylene), fabrics, or other soft material usually with an open end (commonly known as the mouth), and an integral drawstring. Laparoscopic bags may also include rigid, usually detachable, metal wires around the neck to facilitate opening of the bag when deployed; some bags also include a proximal handle. There are a variety of configurations and sizes according to the tissue or organ to be retrieved (e.g., gallbladder, spleen, bowel, kidney, appendix) and/or the procedure performed. Laparoscopy retrieval bags are deployed and retracted using several different techniques that may include catheters, sleeves, rods, and/or cannulae.
