Prosthetic bladder and method of prosthesis implantation
First Claim
Patent Images
1. A prosthetic bladder suitable for implantation in a human patient, comprising:
- a fixed volume reservoir made of material that is biologically compatible with organs surrounding the natural bladder;
an inlet channel integrally formed in the top of said reservoir;
a vent channel integrally formed in said reservoir and extending sufficiently outward from the upper front portion of said reservoir to reach through the abdominal wall of the patient in which said bladder is to be implanted;
a removable perforated cap affixed on the end of said vent channel;
a discharge channel integrally formed in the bottom of said reservoira discharge valve located in said discharge channel; and
a valve actuator coupled to said discharge valve.

Abstract
The present invention relates to a fixed volume prosthetic urinary bladder for use in a human being. The invention, more particularly, concerns a prosthetic urinary bladder comprising a vent channel having a removable cap and a urethral discharge valve. The present invention is intended for implantation in a human being such that the vent channel protrudes through the abdominal wall and the vent cap lies flush with the outer surface of the abdomen.

25. A method for implanting a prosthesis in a human patient comprising the steps of:
-
surgically implanting a deactivated prosthesis in the patient during a first surgical procedure; making anastomotic unions with the prosthesis and the surrounding internal body regions during the first surgical pocedure; allowing the deactivated prosthesis to remain in the patient for a period of several weeks during which time fibroblastic bonding occurs; and making anastomotic union between the prosthesis and the bodily organ to which it is coupled during a second surgical procedure. - View Dependent Claims (26)

27. A method for implanting a prosthetic urinary bladder having a vent channel, an inlet channel, and a discharge channel in a human patient comprising the steps of:
-
implanting a defunctionalized prosthetic bladder in the patient'"'"'s pelvic cavity; coupling the discharge channel of the prosthesis to the patient'"'"'s urethra; allowing the defunctionalized prosthesis to remain in the patient'"'"'s body for a period of at least several days, during which time fibroblastic fixation takes place; surgically removing a plug of abdominal skin at a position on the patient'"'"'s abdomen located over the opening of the prosthesis vent channel; inserting a cylindrical endpiece of sufficient length into the vent channel such that the outer end of the endpiece extends beyond the outer surface of the patient'"'"'s abdomen; waiting a sufficient period of time for the skin and tissue in the vicinity of the endpiece to heal; and coupling the inlet channel of the prosthesis to the patient'"'"'s intestinal conduit. - View Dependent Claims (28)
