ABSTRACT:
A catheter router assembly is disclosed for clearing salt blockages in a previously inserted catheter. A length of flexible, stainless steel cable is provided and a silver solder tip applied at the proximal end of the cable. The silver solder tip is then machined to form a suitable cutting edge for cutting or drilling through the body salts which clog the catheter. A pin vise is secured along the length of the flexible power cable to facilitate insertion of the cable into the catheter and to provide hand rotative power to the cutting tip sufficient to cut through the blocking salts and to clear the catheter for further use. The pin vise may be readily moved along the length of the power cable as necessary to define sufficient free, unsupported forward portions of the cable to reach and clear the blockage throughout the entire length of the catheter.
