The present invention relates to an apparatus and method for performing ERCP and other diagnostic and surgical procedures in the gastrointestinal system. A multiple lumen catheter is inserted into a body duct or conduit through the accessory canal of an endoscopic instrument. The catheter usually includes a cylindrical sleeve and a substantially uniform diameter with a plurality of independent lumens extending the entire length therethrough. The catheter can be used to place stents, visualization materials, and a needle-blade unit to increase access to a common bile duct. |
