Patent number: 5067485Abstract: A technique for the treatment of male impotence. The apparatus to be implanted in the corpus cavernosum of the penis is a cylinder of an implantable polymer. The cylinder is generally flexible and has a plurality of transitions from a lesser diameter to a greater diameter. As the cylinder is filled with fluid under pressure, the areas of lesser diameter tend to expand, thereby effectively lengthening the cylinder without an unacceptable increase in girth. Optional rings may be positioned over the areas of lesser diameter to prevent collapse. An optional outer sheath also improves longitudinal stability.Type: GrantFiled: May 14, 1990Date of Patent: November 26, 1991Assignee: Mentor CorporationInventor: Timothy B. Cowen

Patent number: 5037428Abstract: A vessel approximator for use in anastomosis has a pair of opposed arms, each adapted to fit within the end of a vessel segment to be anastomosed. The tips of the arms are tapered to assist in placing an end of a vessel segment onto the arm. A stem extends from the junction of the arms to form a T shape. The stem is substantially thinner than the arms to permit the ends of the vessel segments placed over the arms to be proximate to each other to be sutured together. A ring on the end of the stem allows the device to be sutered in place in the surgical field. A notch at the junction of the arms opposite the stem permits the arms to collapse together when the device is removed from the vessel segments by pulling on the stem.Type: GrantFiled: June 21, 1990Date of Patent: August 6, 1991Assignee: Applied Medical Technology, Inc.Inventors: George J.

Patent number: 5019061Abstract: A tampon comprises a compacted tampon blank, which in turn is formed by winding a liquid-permeable strip and a string of absorbent material placed thereon to a roll and inserting strip-parts which project from the sides of the string, inwardly of the innermost turn or winding of the roll. In the process of manufacturing the tampon, the strip carrying the string can be wound around a first, tubular mandrel, and one strip-part can be inserted into the mandrel through one open mandrel-end located adjacent the inner edge of the strip-part. A second tubular mandrel is then inserted through the open end of the first mandrel and the first mandrel then withdrawn. With the second mandrel surrounded by the first, inserted strip-part and located with an open end adjacent the inner edge of the other strip-part, the other strip-part is inserted into the second mandrel, which is then withdrawn from the thus formed tampon blank, which is thereafter compacted or compressed.Type: GrantFiled: January 30, 1990Date of Patent: May 28, 1991Assignee: AB Bergasa IndustrierInventors: Ebbe Hoden, Maja Mokvist
