Apparatus and methods for treating the urinary bladder
First Claim
1. A medical device adapted to fit within a patient'"'"'s urinary bladder, the device comprising:
- a liner comprising;
a reservoir;
a first inlet and a second inlet in fluidic communication with the reservoir, each inlet sealably connectable to a respective end of one of the patient'"'"'s two ureters to pass urine into the reservoir; and
an outlet in fluidic communication with the reservoir and extending into the patient'"'"'s urethra to permit voiding of urine from the reservoir, wherein the liner fits within the urinary bladder and substantially isolates urine from the urinary bladder.

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.

18. 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 the patient'"'"'s urinary sphincter; 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 the patient'"'"'s urinary sphincter and the distal ends of the first and second catheters being capable of connection to an external urine collection container.
