Abstract
Methods and systems for treatment of vesicoureteral reflux are disclosed in which a detachable balloon catheter is incorporated into a endoscopic instrument, such as a cystoscopic needle. The needle is directed through the cystoscope and inserted into the subureteral region of the refluxing ureter. A catheter or similar delivery device is inserted into the subureteral region, carrying a balloon. The balloon is then inflated, preferably filled with an inert biocompatible material, and then sealed. After inflation, the balloon is detached and left in the pocket such that the junction of the bladder and ureter is reconfigured to prevent reflux.
