  • Patent number: 4212304
    Abstract: An ureteral catheter stent comprises an elongated, flexible tubular member of uniform outside diameter throughout its length which has proximal and distal ends which are in the form of hooks. Openings extend through the wall of the member to provide passages for fluid to enter the lumen of the tubular member and the proximal end of the member is closed to facilitate its introduction into a body passage. Since the stent is straightened for introduction into a body passage by inserting a wire stylet in the lumen of the stent, the stent is provided with indicating means which show the direction the proximal hook will form when the stylet is removed so that proper placement is insured.

  • Patent number: 4204530
    Abstract: An implantable sleeve for increasing the penile diameter includes a flexible sheet of soft, physiologically acceptable implantable material, said sheet being of sufficient length when formed in the general shape of a cylindrical sleeve to extend from the glans penis to the base of the penis and of a width which is insufficient to completely encircle the penis, but sufficient to cover the corpora cavernosa. The sheet preferably has edges which are rounded and tapered side edges. The sleeve also includes suturing strips on the inside wall of the sleeve adjacent the side edges of the sheet which facilitate the suturing of the sheet to the tunica albuginea. The sleeve further includes porous patches located on the interior of the inside wall of the sleeve into which fibroblasts from the underlying tissues can grow to further anchor the sleeve to the tunica albuginea.

  • Patent number: 4201202
    Abstract: 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.

  • Patent number: 4066073
    Abstract: A penile implant provides a desirable erectness to the penis while at the same time permitting the penis to assume a flaccid position. The implant comprises an elongated rod formed of silicone rubber or other suitable material positionable within the corpus cavernosum of the penis. The rod has axially arrayed sections of various flexural properties. A proximal section suitable for positioning adjacent the pubis is medium stiff in flexure. A longer distal section located in the pendulus penis may be medium stiff or stiffer in flexure. The distal and proximal sections are separated by a very flexible hinge section.
