Abstract
A catheter device for introduction into the body of a being to effect a procedure, e.g., lumen opening, therein. The catheter is an elongated member having a working head at its distal end and is sufficiently flexible and of small diameter to enable it to be located within the body of the being with the working head at the situs of the procedure. The catheter comprises an elongated drive wire extending through the catheter and motion transtator located at the distal end of the catheter. The wire is rotated at a high speed and the transtator translate that rotary motion into high speed reciprocation of the working head. In some embodiments, the motion transtator also causes the working head to be rotated at the same time it is reciprocated. In other embodiments, the working head is only reciprocated. In all cases, the motion of the working head is at a very high speed. The catheter also includes means to provide a fluid therethrough so that when the catheter is used to open a lumen, e.g., an arterial restriction caused by atherosclerotic plaque, the rotation of the working head causes the fluid to impact the artery wall.
