Abstract: An implant for treating male urinary stress incontinence includes a tape (1), and a cushion (5) capable of being filled with fluid, which tape (1) with the cushion (5), when laid onto the patient's urethra, may be looped over the lower pubic branch and may be surgically fixed under tension. For creating such an implant, which may be implanted also without anchoring on the pelvis (8) and which allows for an optimum treatment, it is provided that the tape (1) includes a broadened region (2), to which region (2) the free ends (3) of the tape (1), when implanted, after the loop-over, may be fixed, and in that the cushion (5) is arranged in the region (2), which cushion (5) is connected with a duct (6), which extends outside the tape (1), for supplying and removing the fluid.

Abstract: An instrument for use in the treatment of prolapsed hemorrhoids by applying a purse-string suture includes a tube, which has a distal end, with which it can be inserted forward into the rectum of a patient. The tube also has an open proximal end and a shell wall encompassing an inner hollow space and is provided with an elongated opening. The opening extends in the axial direction of the tube from a distal end to a proximal end. The instrument also includes a closure device, which in a closing position closes the opening and by which the opening can be successively exposed from the distal to the proximal end.

Abstract: A device for generating an artificial constriction in the gastrointestinal tract comprises a band, which can be placed annularly about a particular portion of the gastrointestinal tract, and, by means of a piston-cylinder unit, the size of the passageway opening of the portion of the gastrointestinal tract encompassed by the band is variable, and the band, in the proximity of its first end, is connected with the cylinder of the piston-cylinder unit. The band is connected in the proximity of its second end with the piston of this piston-cylinder unit.

Abstract: A device for generating an artificial constriction in a gastrointestinal tract includes a band, which can be placed annularly about a particular portion of the gastrointestinal tract, having a fillable hollow volume, and a closure device for connecting end regions of the band placed annularly about the portion of the gastrointestinal tract. The closure device is a safety closure, which, at a tear-off tension exceeding a limit value, opens free of destruction, and which can be closed again. This limit value of the tear-off tension is in the range between 20 and 60 N, and preferably between 30 and 50 N.
