Definitions

  • Implantable penile prostheses are well known in the art and generally include a pair of bladder-like penile implants for implantation into the two corpora cavernosa, a fluid transfer system including a reservoir for containing 50 c.c. of a hydraulic liquid fill, and a pump with a set of valves in fluid lines interconnecting the implants with the reservoir.
  • the fluid transfer system is generally constructed of elastomeric compo- nents, including tubing and connectors, and silicone is a typical material used for their construction. Because of its size, the reservoir is generally implanted in the abdomen while the pump is generally bulb-shaped and is typically implanted within the male scrotum.
  • Erection is typically achieved by pumping the bulb-like pump to transfer fluid from the reservoir into the bladder-like penile implants. Examples of these devices are shown in the following U.S. Patents: Patent No. 3,954,102; Patent No. 4,360,010; Patent No. 4,424,807; Patent No. 4,558,693; Patent No. 4,881,530; and Patent No. 5,101,813.
  • the hydraulic fluid generally used in the prior art includes silicone oil, saline, water, and other kinds of non-specific "biocompatible filler". These materials are generally chosen because of their presumed biocompat- ability and/or lubricity.
  • a biocompatible fill is suggested which may be doctored with a biocompatible radiopaque dye in order to facili ⁇ tate the tracing of any leaks from the system to thereby localize and minimize the required surgical intrusion to correct the leak.
  • the tracing of leaks is an important consideration for prior art penile implants because of their regular use and resulting significant incidence of failure. In performance of the intended use of penile implants, there is a regular cycling of the hydraulic fill from the reservoir to the bladders and then back again.
  • This invention is a good and valuable invention which enhances the chances for early detection of cancer in performing mammographies on female breasts which are augmented with this breast implant.
  • the inventors herein are also aware of pending U.S. Application Serial No. 07/952,687 filed September 29, 1992 entitled Breast Implant With Radiolucent Shell , the rights to which are owned by the assignee of the present invention and the disclosure of which is incorpo- rated herein by reference, which discloses and claims a breast implant having a shell made with radiolucent mate ⁇ rials instead of the silicone shell predominantly found in the prior art.
  • radiolucent materials in the shell eliminates the last vestiges of artifacts which might otherwise appear on a radiograph when a mammograph is taken of a breast with an implant having radiolucent fill only. This is an important and valuable invention which improves on the '882 patent and demonstrates its usefulness in those implants for which mammography is customarily used for the early detection of cancer.
  • the inventors herein have developed a penile implant using triglyceride as the hydraulic fill, partial radiolucency of the im- plant structure to enhance leak detection, a radiopaque dye for the fill which does not metabolize too rapidly to hinder leak detection, and texturing to eliminate failure of otherwise failure prone implant parts.
  • Significant advantages have been obtained on several grounds.
  • the radiolucency of the fill and bladder permits the utilization of an x-ray technique having greatly reduced intensities and exposure times to view at least the blad ⁇ der portion in the patient's penile shaft for leak detec ⁇ tion.
  • the implant bladders may be made of radiolucent material, and a radi ⁇ opaque dye added to the triglyceride fill.
  • Texturing may also be used in the implant bladders to decrease the tendency for fold flaw failure as the texturing will enhance the inte- gration of the bladder surface with the surrounding tis ⁇ sue thereby preventing kinking or accute folding upon deflation.
  • the figure is a cross-sectional view of a penile implant with hydraulic system implanted in a patient. Detailed Description of the Preferred Embodiment
  • a penile implant 12 is implanted in the penis 10 of a male patient that includes a bladder 14 having surface texturing on the exterior surface thereof.
  • the bladder 14 may be made from any of the radiolucent materials previously disclosed in the related application cross-referenced above.
  • a tubing 16 interconnects the bladder 14 with a pump 18 filled with a hydraulic fill 20 which may be any suitable triglyceride, such as peanut oil or soybean oil. Any suitable bio- compatible material demonstrating the same approximate degree of lubricity and metabolic rate to enhance leak detection may be used. Generally, these materials com ⁇ prise triglycerides.
  • Another tubing 22 connects the pump 18 with a reservoir 24 implanted in the abdomen 28 area of a patient's body, with the exterior surface of reser ⁇ voir 24 having texturing 26.
  • the surface texturing of the bladder and reservoir helps resolve different problems previously experienced in prior art penile implants.
  • the surface texturing helps to prevent the kink ⁇ ing in the bladder as tissue grows into the fold general ⁇ ly created as the bladder 14 deflates and the penis 10 fold over or bends downwardly to become less obtrusive.
  • the reservoir 24 as mentioned above a scar capsule can form around the reser ⁇ voir 24 and contract which would impede its being re ⁇ filled with hydraulic filler as required to deflate the implant.

Abstract

Une prothèse ou un implant péniens (12) mettent en oeuvre des cylindres ou vessies (14) expansibles implantés dans le pénis conjointement avec un système de transfert de fluide comprenant une pompe (18), un réservoir hydraulique (24), et des canalisations de fluide reliées entre elles, des raccords, etc. Cette prothèse comporte comme fluide hydraulique (20) un triglycéride biocompatible assorti d'un colorant radio-opaque, utilise des matériaux moyennement transparents aux rayons X pour former la vessie (14) afin d'améliorer la détection des fuites. La surface extérieure du réservoir et des vessies est texturée de manière à réduire la probabilité de rupture par fissure au niveau des replis ou bien contracture capsulaire.
