Title: Methods and apparatus for deploying ureteral stents

Abstract: A ureteral decompression device comprises a guide member and an anchoring structure. The guide member may be introduced through the urethra and bladder into the ureter so that the anchor structure passes a lodged kidney stone. Once past the stone, the anchor structure can be compacted to anchor the guide member in place. The anchor structure will permit leakage and the guide member will provide a leakage path directly past the stone, thus decompressing the kidney.
