First Claim
Patent Images
1. A method of treating vesicoureteral reflux comprising;
- providing a cystoscopic system comprising a sheath, a viewing means for viewing a distal site and a positioning element extending longitudinally through the sheath;
inserting the sheath through the urethra of a patient;
passing an uninflated, detachable balloon attached to a catheter through a lumen of the positioning element to a subureteral region of a reflux-prone bladder; and
inflating and detaching the balloon from the catheter in place such that the ureter is repositioned to provide a competent ureterovesical junction while endoscopically visualizing the compressive effect of the balloon on the surrounding tissue.

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.

11. A system for the deployment of a detachable balloon comprising:
-
a cystoscopic system comprising a sheath, a viewing means for viewing a distal site and a positioning element extending longitudinally through the sheath; and a balloon catheter including an uninflated, detachable balloon attached thereto, said positioning element having a longitudinal lumen therethrough, means for passing said balloon through said lumen of said positioning element, and means for inflating and detaching said balloon from said balloon catheter. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
