Abstract: A device for use for the treatment of a hemorrhoid prolapse, particularly by HAL surgery, attaching a tightening suture, or a rubber band ligation, using a tube having a tube shell wall and a closing device having a closure shell wall enclosing a hollow space. The tube shell wall is supported displaceably and/or rotatably in the hollow space of the closure shell wall, and the tube shell wall and the closure shell wall can be inserted into a rectum of a patient. The tube shell wall has at least one tube wall opening, and the closure shell wall has at least one closure shell opening which can be at least partially aligned with one another in an open position with a web arranged thereof protruding at least partially into the tube shell opening and/or into the closure shell opening.

Abstract: An apparatus is provided that is adapted to be used in training surgeons and surgical personnel in surgical techniques and procedures, and more particularly to an apparatus and method for training surgeons and surgical personnel in minimally invasive surgical techniques and procedures in a manner which closely replicates clinical phenomena. The apparatus of the invention includes a frame, a pump, appropriate tubing and a reservoir containing a volume of fluid. Non-living animal tissue is joined to the tubing at the outlet side of the pump and surgical personnel are permitted to conduct surgical techniques thereon.

Abstract: A device for selectively opening and closing a tubular body organ comprises a sleeve adapted to encircle the body organ and formed with a pressurizable compartment between inner and outer walls. The sleeve is connected by a duct to a supply vessel which is compressible to express a pressure medium into the sleeve by manipulation externally of the body. The supply vessel, which is implanted below the skin of the patient, is provided with means for retaining it in a compressed state, thereby retaining the blocked state of the body organ and preventing passage of a body material, e.g. feces or urine, therethrough. The latter means can be released to permit expansion of the supply vessel and hence return a fluid from the sleeve into the vessel.
