Patent attributes
The present disclosure relates generally to thrombectomy devices. An exemplary catheter comprises: an emitter assembly comprising at least one emitter; wherein each emitter comprises an electrode pair, and wherein each emitter is configured to generate a plurality of cavitation bubbles when a voltage is applied to the pair of electrodes; an infusion lumen formed by at least a portion of an outer wall of the catheter, the infusion lumen configured to receive a conductive fluid, wherein the emitter assembly is housed within the infusion lumen, wherein a distal segment of the infusion lumen includes a plurality of holes on the portion of the outer wall of the catheter, and wherein the plurality of holes are configured to release the conductive fluid and the plurality of cavitation bubbles out of the catheter to treat thrombus at a treatment site; an aspiration lumen including aspiration ports at the distal segment thereof.
