Abstract
Method and apparatus for opening a partially or totally occluded blood vessel. A conventional catheter is inserted within a patient and the condition of a blood vessel ascertained. If it is determined that sufficient blockage exists to cannulize the vessel, a small diameter drive catheter having a rotatable head at a distal end is inserted into the conventional catheter in close proximity to the occluded region. The head is rotated at high speeds as dye is injected through the catheter to monitor progress of the procedure. Different sized rotating heads having different blockage removing characteristics are inserted until the procedure has been completed to the physician's satisfaction. The drive mechanism is a small d.c. powered hand-held motor operated by the physician during the procedure.
