ABSTRACT:
An expandable catheter and bridge device for use in endoscopic/cystoscopic procedures utilizing a laterally flexible tubular catheter includes a longitudinally expandable section, and further comprising a rigid bridgelike handle structure to facilitate catheter maneuvering and deployment manipulation. The catheter tube is insertible through a passage of an endoscopic instrument while the catheter's expandable section is expanded in length through the coaction of manually applied tension and the expanding means disposed in one of the catheter-encircling ends of the bridge-like handle structure as the catheter is drawn therethrough. At the other catheter-encircling end, the bridge-like handle structure is secured to a passage entry of the endoscopic instrument. The bridge-like handle structure is provided with a snap-in cradle fitting to securely hold a syringe which can be connected to the end of the catheter tube.
