Procedures and devices for opening restrictions, e.g., occlusions, in passageways, e.g., arteries, of living beings. The device basically comprises an elongated, flexible recanalization catheter arranged to be threaded through the passageway to the site of the restriction. The catheter includes a working head which is adapted to be moved, e.g., rotated, by turbine drive while the head is advanced into the restriction to effect its opening. Blocking structure is provided for use with the catheter to preclude any debris produced during the restriction opening procedure from flowing distally down the passageway. Profusion structure is also provided to provide oxygenated fluid, drugs, contrast media or dyes into the passageway. One embodiment of the recanalization catheter is a combination device having different diameter sections for introduction into a large passageway within the body while the working head is located within a small remotely located passageway.
