Abstract

Disclosed are devices and methods for treating disease in a urinary bladder. The devices include a bladder liner for insertion into the urinary bladder and catheters positioned within the urinary bladder to carry urine from the ureters to an outside collection container. The bladder liner and catheters are constructed of biocompatible materials and are configured to create a seal with the urethra and ureters. The bladder liner may be adapted to deliver medicinal agents to the urinary bladder. Methods of treating disease in the urinary bladder include isolating urine from the bladder wall to allow sufficient time for the bladder wall to heal e.g., by implanting the aforementioned devices. Healing or pain relief may be enhanced by instilling pharmaceutical agents between the liner and bladder wall without dilutional effects.

Claims

1. An apparatus for isolating urine from a patient'"'"'s urinary bladder, the apparatus comprising:

a first catheter positionable in the patient'"'"'s first ureter, the first catheter including a proximal end and a distal end, the proximal end of the first catheter including a ureter to catheter seal;

a second catheter positionable in the patient'"'"'s second ureter, the second catheter including a proximal and a distal end, the proximal end of the second catheter including a ureter to catheter seal; and

a third catheter, including a proximal end and a distal end, wherein the proximal end of the third catheter is connected to and joins the distal ends of the first and second catheters and the distal end of the third catheter being capable of passing through the patient'"'"'s urethra and connection to an external urine collection container.

2. The apparatus of claim 1, wherein the third catheter includes a valve disposed between a distal end of the patient'"'"'s urethra and the distal end of the third catheter.

3. The apparatus of claim 1, wherein the seals are composed of at least one biocompatible adhesive.

4. The apparatus of claim 1, wherein the catheters are composed of materials selected from the group consisting of vinyl, polyethylene, PVC, EVA silicone, latex, and polypropylene.

5. An apparatus for isolating urine from a patient'"'"'s urinary bladder, the apparatus comprising:

a first catheter positionable in the patient'"'"'s first ureter, the first catheter including a proximal end and a distal end, the proximal end of the first catheter including a ureter to catheter seal, the distal end of the first catheter being capable of passing through a suprapubic incision in the patient'"'"'s abdomen; and

a second catheter positionable in the patient'"'"'s second ureter, the second catheter including a proximal end and a distal end, the proximal end of the second catheter including a ureter to catheter seal, the distal end of the second catheter being capable of passing through a second suprapubic incision in the patient'"'"'s abdomen, wherein the distal ends of the first and second catheters are capable of connection to at least one external urine collection container.

6. The apparatus of claim 5, wherein the catheters are composed of materials selected from the group consisting of vinyl, polyethylene, PVC, EVA silicone, latex, and polypropylene.

7. An apparatus for isolating urine from a patient'"'"'s urinary bladder, the apparatus comprising:

a first catheter positionable in the patient'"'"'s first ureter, the first catheter including a proximal end and a distal end, the proximal end of the first catheter including a ureter to catheter seal;

a second catheter positionable in the patient'"'"'s second ureter, the second catheter including a proximal and a distal end, the proximal end of the second catheter including a ureter to catheter seal; and

a third catheter, including a proximal end and a distal end, wherein the proximal end of the third catheter is connected to and joins the distal ends of the first and second catheters and the distal end of the third catheter being capable of passing through a suprapubic incision in the patient'"'"'s abdomen and connection to an external urine collection container.

8. The apparatus of claim 7, wherein the catheters are composed of materials selected from the group consisting of vinyl, polyethylene, PVC, EVA silicone, latex, and polypropylene.
