Abstract
Abstract An implant prosthesis for surgically by-passing the distal portion of the natural urethral tract for the removal of biological liquids, especially urine, consists of one or more artificial ureters disposed in a conical sheath connected with flexible tubing joining a tank forming a bladder replacement which in turn is connected by flexible tubing to the urethra when retained or extends to provide a controlled valved vent at the surface of a patient's body in which the prosthesis is surgically implanted, as for example following the removal of bladder cancer and its associated damaged distal urinary system.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
189 words
A surgically implantable distal urinary replacement prosthesis for the collection and removal of urine from at least one kidney in a patient's body and comprising at least one flexible cone-shaped sheath having a first open end arranged for engagement about and attachment to at least a portion of said kidney so as to enclose the renal pelvis area thereof, a second end of said cone-shaped sheath being spaced from said renal pelvis area, a flexible tubular replacement ureter positioned partially within said cone-shaped sheath and extending outwardly thereof through said second end thereof and attached thereto in sealing relation, an end of said flexible tubular replacement ureter located within said cone-shaped sheath and arranged for engagement over a ureter in said renal pelvis area and adapted to be attached thereto, openings in said flexible tubular replacement ureter within said flexible cone-shaped sheath so that liquid within said flexible cone-shaped sheath can flow into said tubular replacement ureter, a tank forming a replacement bladder, said tubular replacement ureter being in communication with said tank and a flexible tubular member communicating with said tank and forming a discharge passageway extending therefrom.
Claim 2
Dependent Claim
189 words
A surgically implantable distal urinary replacement prosthesis for the collection and removal of urine from at least one kidney in a patient's body and comprising at least one flexible cone-shaped sheath having a first open end arranged for engagement about and attachment to at least a portion of said kidney so as to enclose the renal pelvis area thereof, a second end of said cone-shaped sheath being spaced from said renal pelvis area, a flexible tubular replacement ureter positioned partially within said cone-shaped sheath and extending outwardly thereof through said second end thereof and attached thereto in sealing relation, an end of said flexible tubular replacement ureter located within said cone-shaped sheath and arranged for engagement over a ureter in said renal pelvis area and adapted to be attached thereto, openings in said flexible tubular replacement ureter within said flexible cone-shaped sheath so that liquid within said flexible cone-shaped sheath can flow into said tubular replacement ureter, a tank forming a replacement bladder, said tubular replacement ureter being in communication with said tank and a flexible tubular member communicating with said tank and forming a discharge passageway extending therefrom.
Claim 3
Dependent Claim
27 words
The prosthesis set forth in claim 1 and wherein said cone-shaped sheath and said flexible tubular replacement ureter are sufficiently porous to allow tissue cellular colonization thereinto.
Claim 4
Dependent Claim
59 words
The prosthesis set forth in claim 1 and wherein a valve is incorporated in the flexible tubular replacement ureter at its point of communication with said tank forming the replacement bladder, said valve arranged to permit the flow of fluid from said ureter into said tank and to prevent the flow of fluid from said tank into said ureter.
Claim 5
Dependent Claim
40 words
The prosthesis set forth in claim 1 and wherein said flexible cone-shaped sheath is formed of a material that may be split to provide passageways for blood vessels and an adjustment of size with respect to registration with said kidney.
Claim 6
Dependent Claim
76 words
The prosthesis set forth in claim 1 and wherein the end of said flexible tubular replacement ureter positioned within said cone-shaped sheath is progressively enlarged toward its open end and split longitudinally through said enlarged area and fastening configurations are formed on either side of said split whereby the diameter of the enlarged end may be adjusted and secured in adjusted relation when engaged over a portion of a natural ureter in said renal pelvis area.
Claim 7
Dependent Claim
47 words
The prosthesis set forth in claim 1 and wherein the flexible tubular member communicating with the tank and forming a discharge passageway extending therefrom defines two tubular passageways, a flexible tube communicating with one of said passageways and extending into said tank to form an air vent.
Claim 8
Dependent Claim
71 words
The prosthesis set forth in claim 1 and wherein the flexible tubular member communicating with the tank and forming a discharge passageway extending therefrom defines two tubular passageways, a flexible tube communicating with one of said passageways and extending into said tank to form an air vent and wherein a manually movable valve element is attached to the end of the flexible tubular member in oppositely disposed relation to said tank.
Claim 9
Dependent Claim
52 words
The prosthesis set forth in claim 1 and wherein the cone-shaped sheath, the flexible tubular replacement ureter, the tank forming the bladder replacement and the flexible tubular member communicating with the tank and forming a discharge passageway are separately formed portions of the prosthesis and joined to one another by separable connections.
Claim 10
Dependent Claim
22 words
The prosthesis set forth in claim 1 and wherein the several sections thereof are X-ray coded and banded for visual X-ray examination.
Claim 11
Dependent Claim
16 words
The prosthesis set forth in claim 1 and wherein radiographic markers are incorporated in the prosthesis.
Claim 12
Dependent Claim
35 words
The prosthesis set forth in claim 1 and wherein the cone-shaped sheath is of a size and shape for encompassing the circumference of said kidney whereby any and all leakage would be within said sheath.
Claim 13
Dependent Claim
45 words
The prosthesis set forth in claim 1 wherein several apertured tabs are formed on said cone-shaped sheath and on said tank and arranged to provide members attachable to portions of said patient's body for supporting said sheath and tank in operative relation to said kidney.
Claim 14
Dependent Claim
19 words
The prosthesis set forth in claim 1 and wherein said tank is collapsible upon itself as liquid drains therefrom.
