Abstract
The disposable intra-luminal ultrasonic instrument comprises: a catheter having an elongate axis and a hollow distal end portion; an acoustical mirror face; structure for mounting the acoustical mirror face for rotation in the distal end portion of the catheter with the acoustical mirror face arranged at an angle to the elongate axis of the catheter; a transducer; structure for mounting the transducer in the distal end portion of the catheter in a position to propagate acoustic waves toward the acoustical mirror face; a micromotor having a length no greater than approximately 6 millimeters and a diameter no greater than approximately 2.4 millimeters; structure for mounting the micromotor in the distal end portion of the catheter; structure for connecting the micromotor to the acoustical mirror face; conductors for connecting the micromotor to a source of energy for energizing the micromotor to rotate the acoustical mirror face; and, conductors for connecting the transducer to a source of energy for energizing the transducer to produce and supply sound waves to the rotatable acoustical mirror face.
