ABSTRACT:
A dilitation catheter is disclosed including an elongate tubular body and a control rod extending therethrough from a proximal control end to a distal operating end. Adjacent the distal operating end is a pair of rigid or semi-rigid jaws which when closed substantially extend to a point. The jaws are hinged together at there rear by one of a pair of pivotal hinges or a resilient tubular section which allows the jaws to move between a closed position and an open position axial movement of the control rod. In one aspect of the invention, a resilient connection between the jaws and the elongate tubular body is foraminous to allow flow of bodily fluids through the operating jaws end of the catheter while the jaws are expanding luminal walls in a patient's body. Also, a guide wire may be utilized through the elongate tubular body and the operating jaws to provide for more exact placement of the operating end of the catheter.
