Abstract
A medical device for enclosing an internal body organ or tissue during surgery, especially endoscopic surgery. The device has a strand with loop and free end portions, the free end portion enclosed within a cannula. The loop has a cinch. The device has a surgical pouch with an opening or mouth. The pouch is mounted to the loop portion at the open end of the pouch. An optional frangible end of the cannula allows for pulling the free end portion proximally to reduce the diameter of the noose portion so as to close the open end of the surgical pouch. The surgical pouch has a shape memory effect metal insert so that the pouch automatically unfurls or unwinds in a patient's body cavity. The device may also have a shape memory effect metal loop which also automatically opens the mouth of the pouch in the patient's body.
