ABSTRACT:
A rotationally vibrating imaging catheter and method of utilization has an array of ultrasound or optical transducers and an actuator along with signal processing, display, and power subsystems. The actuator of the preferred embodiment is a solid-state nitinol actuator. The actuator causes the array to oscillate such that the tip of the catheter is rotated through an angle equal to or less than 360 degrees. The tip is then capable of rotating back the same amount. This action is repeated until the desired imaging information is acquired. The rotationally vibrating catheter produces more imaging points than a non-rotating imaging catheter and eliminates areas of missing information in the reconstructed image.Rotationally vibrating catheters offer higher image resolution than stationary array catheters and greater flexibility and lower costs than mechanically rotating imaging catheters.The rotationally vibrating array carried on a catheter is vibrated or rocked forward and backward to allow for acquisition of three-dimensional information within a region around the transducer array.The addition of adjunctive therapies to the imaging catheter enhances the utility of the instrument. Examples of such therapies include atherectomy, stent placement, thrombectomy, embolic device placement, and irradiation.
