Abstract:
A catheter for treating a vascular occlusion comprising:an elongated shaft including a proximal section and a distal section, wherein the shaft is formed with at least one lumen extending from the proximal section to the distal section, wherein the distal section includes a hub defined by an external surface and a collar section around the external surface; at least one spreading member formed at the distal section of the shaft, wherein the at least one spreading member comprises a free distal end that moves laterally away from the longitudinal axis of the shaft to disrupt a vascular occlusion in peripheral vasculature, wherein the at least one spreading member includes a cam follower; and an actuating assembly positioned along the elongated shaft to move the distal end of the at least one spreading member in response to an actuation force, wherein the actuating assembly includes an actuation element including a distal end and a cam formed at the distal end for communication with the cam follower to urge the at least one spreading member in a substantially lateral direction.
