Abstract
The present invention is an ultrasonic thrombectomy catheter that produces physical forces (shear rates) strong enough to emulsify obstructions such as thrombi and emboli without causing damage to arterial walls. This is accomplished by properly arranging piezoelectric transducers within a catheter and a tubular catheter head separated by a gap to generate acoustic streaming that simultaneously emulsifies the obstruction and sweeps resulting debris into a catheter lumen for removal. The open gap may be formed by supporting struts that connect the catheter to the catheter head. The design of the catheter tip allows the fabrication of catheters capable of removing partial or complete blockages from arteries and other vessels having diameters as small as 2 mm.
