Abstract

Apparatus (20) is provided for removing plaque from a blood vessel of a subject, including a catheter (22) shaped to define an opening that is placed in the blood vessel. A pressure source propels a fluid jet through the opening, and a pressure sensor (38) detects a pressure in the blood vessel induced by the jet. A control unit (28) steers the jet in response to the detected pressure. Other embodiments are also described.
