Patent number: 4602625Abstract: A penile erectile system for treating male impotency comprises a sleeve of biocompatible material having at least one pressurizable chamber which is adapted to be implanted about the penile shaft of a patient beneath the penile skin between the skin and the shaft and a body member integrally attached to said sleeve. The body member comprising a fluid reservoir for pressurizing fluid, and a pump for transferring the fluid under pressure from the reservoir to the chamber.Type: GrantFiled: February 22, 1985Date of Patent: July 29, 1986Assignee: Medical Engineering CorporationInventors: Daniel Yachia, Henry W. Lynch

Patent number: 4586505Abstract: A laryngeal and tracheal stent which can be used to reconstruct the larynx or trachea consists of an elongated cylindrical stenting cuff with an independently inflatable retention cuff at the top and a second independent inflatable retention cuff at the bottom. The stent also has individual cuff pilot tubes for separately inflating or aspirating the stenting, top and bottom cuffs, and guide means for moving the stent into place.Type: GrantFiled: May 3, 1984Date of Patent: May 6, 1986Assignee: Universal Prosthetics, Inc.Inventors: George A. Sisson, Robert E. Berktold, Henry W. Lynch

Patent number: 4550719Abstract: A penile erectile system which is adapted to be surgically implanted in man for the treatment of erectile impotence includes at least one penile implant comprising an elongated, flexible cylindrical body (11, 11') adapted to be implanted in the corpus cavernosum of a penis, said body having a tip (14) at one end and an anchoring stem (12) at the other end and an intermediate section (13) including a pair of inner (17) and outer (18) chambers substantially filled with fluid (20) and connected by a passage (21). The body (11, 11') also includes internal pump means (19) adjacent the stem for transferring fluid into the inner chamber (17) and a control valve (29) adjacent the tip (14) for controlling pressure in the inner chamber (17). The inner chamber (17) is non-distensible so that when it is filled and pressurized by transferring fluid thereto it becomes rigid and supports the penis in an erectile state.Type: GrantFiled: November 9, 1983Date of Patent: November 5, 1985Assignee: Medical Engineering CorporationInventors: Roy P. Finney, Robert E. Trick, Henry W. Lynch

Patent number: 4523584Abstract: A penile erectile system for treating male impotency comprises a sleeve of biocompatible material having at least one pressurizable chamber which is adapted to be implanted about the penile shaft of a patient beneath the penile skin between the skin and the shaft, a fluid reservoir of pressurizing fluid, and a pump for transferring the fluid under pressure from the reservoir to the chamber. The system also includes tubing connecting the reservoir and pump to the pressurizable chamber and a valve for controlling the flow of fluid into and out of the pressurizable chamber. In a preferred embodiment, a pressure bulb serves both as the fluid reservoir and the pump.Type: GrantFiled: March 4, 1983Date of Patent: June 18, 1985Assignee: Medical Engineering CorporationInventors: Daniel Yachia, Henry W. Lynch

Patent number: 4489722Abstract: A catheter such as an endotracheal tube is rendered resistant to laser beam impaction by coating the cuff and/or the tube with a laser-reflective compound which is preferably comprised of one to three parts of powdered aluminum to one part silicone rubber solution. The laser-reflective compound may be permanently bonded to the cuff and/or the tube by first dipping the cuff and/or the tube in a bath of the compound to form a smooth outer coating on the cuff and/or the tube and then baking the cuff and/or the tube to cure the coating. The laser-reflective coating serves to reflect the laser beam, thus making the catheter laser resistant while the smoothness of the coating aids in catheter insertion.Type: GrantFiled: September 27, 1982Date of Patent: December 25, 1984Assignee: Medical Engineering CorporationInventors: Rick J. Ferraro, Henry W. Lynch

Patent number: 4353360Abstract: A penile erectile system which is adapted to be surgically implanted in man for the treatment of erectile impotence includes a penile implant comprising an elongated, flexible cylindrical member adapted to be implanted in the corpus cavernosum of a penis, said member including a pair of inner and outer chambers substantially filled with fluid and connected by a passage. The innermost of said chambers being non-distensible so that it is filled and pressurized by transferring fluid thereto from the outer chamber and it becomes rigid and supports the penis in an erectile state.Type: GrantFiled: October 31, 1980Date of Patent: October 12, 1982Assignee: Medical Engineering CorporationInventors: Roy P. Finney, Henry W. Lynch

Patent number: 4335714Abstract: An implant useful for the surgical construction of a penis comprises an elongated member having a pair of stems at the proximal end for anchoring the member in the pubic area of a patient, and a trunk with a urethra receiving and supporting groove and an open distal end. In the preferred embodiment, the implant is made completely of silicone elastomer. A method of constructing a penis using the implant is also described.Type: GrantFiled: July 17, 1980Date of Patent: June 22, 1982Assignee: Medical Engineering CorporationInventors: Milton T. Edgerton, Roberto C. Granato, Henry W. Lynch

Patent number: 4201202Abstract: A penile prosthesis which is adapted to be surgically implanted in man for the treatment of erectile impotence includes two separate penile implants each comprising an elongated, flexible rod having a short proximal portion of relatively stiff material which is adapted to be implanted into the root end of the corpus cavernosum to support the implant and a longer distal portion of softer material which is adapted to be implanted into the corpus cavernosum of the pendulus penis. A flexible, cylindrical sleeve is positioned axially about an intermediate section of the distal portion of the rod and is sealed at its ends to the rod in a fluid tight manner to form a chamber for pressurizing fluid. The implant also includes a pressure bulb for pressurizing fluid; tubing communicating between the chamber and the pressure bulb; and valve means for controlling the flow of fluid between the pressure bulb and the chamber.Type: GrantFiled: September 25, 1978Date of Patent: May 6, 1980Assignee: Medical Engineering Corp.Inventors: Roy P. Finney, Henry W. Lynch
