ABSTRACT:
An improved percutaneous angioscopy catheter having a multipurpose lumen to allow simultaneous irrigation and passage of an angioscope. The angioscopy catheter includes an elongated flexible tube having a distal end adapted for insertion through a blood vessel of a patient and a proximal end adapted for connection to apparatus disposed outside the body of the patient. The elongated flexible tube also has a central lumen extending axially through the tube which is adapted to irrigate the blood at the distal end of the angioscope and changeably mount an angioscope through the central lumen. In one embodiment, the elongated flexible tube further includes at least one balloon lumen extending axially through the tube and an inflatable occlusion balloon near the distal end of the tube, and at least one stranded stainless steel wire extending axially through the tube in order to provide a predetermined rigidity to the tube. A coil spring may also be provided along the wall of the central lumen for facilitating the insertion of an angioscope through the central lumen.
