Abstract: An improved skin expansion device includes an inflatable envelope fluidly connected through a base thicker than the envelope to a conduit in fluid connection with an injection chamber. The base fluidly connects the conduit to the inflatable envelope through at least one fluid channel extending between a position proximate the perimeter of the base to an inwardly disposed location in fluid communication with the interior of the inflatable envelope. The conduit is connected to the base along the perimeter and in fluid communication with the fluid channel.

Abstract: An improved self-sealing valve for use in a fluid fillable device includes a main body portion and a channel within the main body portion for receiving a fill tube. The improvement includes a sealing portion with the channel extending therethrough and movable from a fluid flowable position with the fill tube inserted in the channel to a curled, fluid sealing position when the fill tube is removed from the channel.

Abstract: A urine collection catheter having a tubular portion open at its outer end and designed to be connected to a urine receptacle and a cup or cone shaped portion integrally connected to the inner end of said tubular portion, the cup shaped portion being of a shape to conform generally with that of the tip or head or glans of a typical penis. The cup shaped portion has a pressure sensitive adhesive on the inner surface to enable the catheter to adhere to the head of a penis when the catheter is pressed into engagement with the penis. The cup shaped portion is conical and is connected to the tubular member by a bulbous portion to receive surges of urine. In one version, the thickness of the cup shaped portion decreases from its outer to its inner end.

Abstract: A male contraceptive hood which is adhesively secured to the penis, the hood being initially rolled up and the interior of the hood being free of adhesive until it is unrolled. The hood has a thin sheath which serves as the contraceptive device and an outer cylindrical member which is initially rolled together with the thin sheath. The outer cylindrical member has an adhesive on a portion of its outer surface, separated from the outer surface by a release agent, the adhesive being transferred to the inner surface of the sheath as the hood is unrolled onto a penis. The outer member can then be removed leaving only the thin inner sheath on the penis. A projecting portion is provided on the outer member for grasping the outer member to remove it.In a preferred form, a lubricant is disposed between the sheath and the inner surface of the outer cylindrical member. This lubricant remains on the outer surface of the sheath to facilitate removal of the outer member and also to aid in intercourse.

Abstract: A surgically implantable prosthesis such as a mammary implant, that is rendered rupture-resistant by a lubricious layer bonded to the inner surface, outer surface, or both such surfaces of a wall of a flexible, creasable shell of the prosthesis. The lubricious layer reduces self-abrasion damage between sliding surfaces of the shell in a folding or creased area of the shell after surgical implantation. The lubricious layer can be mechanically bonded, such as through physical locking within an interpenetrating lattice structure of such wall, or can be attached to the shell's wall through a covalent chemical bond. An example of the rupture-resistant prosthesis includes a lubricious layer of an acrylamide polymer radiation bonded to at least one wall surface of a silicone shell or bag.

Abstract: A gastric band device for forming a stoma opening in a stomach for treatment of morbid obesity includes a flexible substantially nonextensible band portion having an expandable section that is expandable and deflatable through an injection site. After the nonextensible band portion has been positioned around the stomach to form the stoma opening, the expandable section is used to adjust the diameter of the stoma opening.

Abstract: A penile prosthesis which is adapted for surgical implantation includes a pair of fluid fillable prosthetic members and a fluid reservoir containing a supply of the fluid. A pump pumps fluid from the reservoir to the prosthetic members. The pump includes a valving section which is fluidly connected with the reservoir and the prosthetic members, and a pumping section for pumping the fluid from the reservoir to the prosthetic members. The valving section includes a deformable housing with a supply inlet passage fluidly connected to the reservoir and two outlet passages, each outlet passage fluidly connected to a corresponding prosthetic member. Each passage has a check valve for directing the flow of fluid from the reservoir, through the pumping section and into the prosthetic members. When the valving section is manually deformed, the check valves are placed in an inoperable state permitting flow of the fluid from the prosthetic member, through the pumping section, and back into the reservoir.

Abstract: A connector device fluidly connects first and second sections of a highly elastic, highly compressible tubing of an implantable device such as an implantable penile prosthesis. The connector device includes a rigid connector component having a longitudinal main body with a fluid passage extending between first and second ends. The outer surface of the connector component includes a center surface section and first and second frusto-conical surfaces disposed at the first and second ends. The frusto-conical surfaces increase in diameter towards the center section, until the frusto-conical surfaces are larger in diameter than the center section. The tubing elastically engages the frusto-conical surfaces and a clamp surrounds the tubing preventing the tubing from "creeping" off the frusto-conical surfaces.

Abstract: A male urinal device (10) is disclosed. Device (10) includes a laminated sheath (14) having an inner layer (26) of latex rubber and an outer layer (28) of silicone rubber. Adhesive (24) is stored between the inner and outer layers (26, 28) when sheath (14) is rolled. As sheath (14) is unrolled, adhesive (24) is released from outer layer (28) and adheres to inner layer (26). Upon pressing sheath (14) to a penis (12), a leak-free bond is created.

Abstract: A sheath arrangement for a male urinal device having a urinal sheath of flexible material, designed for application to a penis for covering a substantial portion thereof lengthwise of the same and having a lower portion for connection to a urine receptacle, and a liner pad of resilient, compressible, deformable, waterproof material in the form of a strip of such material having a width sufficiently narrow to allow the strip to be wound spirally to extend over a portion of the penis beneath the sheath much greater in length than the width of the strip. The material of the pad is sufficiently deformable to ensure liquid tight engagement of the overlapping portions of the pad with the penis. Preferably, both the inner surface and the outer surface of the pad are adhesive so that not only is the liner pad held in place on the penis but the sheath is also held against movement with respect to the liner pad. The sheath arrangement is formed by spirally winding the liner pad firmly around the penis.

Abstract: A sampling catheter having an outer tube of resilient material with a normally closed distal end and an inner flexible tube which is longer than the outer tube and which is normally held in retracted position with respect to the distal end of the outer tube by means of a loop of the inner tube which is fastened to the outer tube. The assembled catheter is disposed in a sealed package with the inner tube in such retracted position.

Abstract: An implantable unit for stimulating an internal body organ in which there is a power supply portion for having power induced therein from a source external of the body and electrodes adapted to be attached to a muscular organ such as a bladder or the like, said unit having an energy storage device, such as a capacitor, connected to the electrodes under the control of a transistor which is normally maintained non-conductive as a result of the voltage drop across an impedance connected to the power supply so that each time that the power supply is interrupted, the transistor becomes conductive to discharge the energy storage device through the electrodes and apply a stimulating voltage to the organ. The transmitter source external of the body is designed to periodically interrupt for a short period the voltage transmitted thereby so that the voltage produced by the power supply of the implantable unit is thus periodically interrupted.
