Abstract
A medical device comprises a catheter and an aspiration pump. The catheter has a hybrid reinforcement to improve performance characteristics. The aspiration pump is cycled to improve aspiration efficacy.
Claims14
An endovascular catheter comprising:
- an elongate catheter body having a proximal end, a distal end and a central lumen extending longitudinally through the catheter body, wherein the catheter body comprises a catheter wall that has an inner liner, a hybrid reinforcement, a distal tip and a variable durometer outer jacket,
- wherein the hybrid reinforcement comprises a helical coil and a braid that encircles the helical coil, and a radiopaque marker positioned on the distal end of the catheter body about the outer circumference of the hybrid reinforcement,
- wherein the distal end of the helical coil and the distal end of the braid are terminated between distal and proximal ends of the radiopaque marker located on the distal end, and wherein the inner liner is at least partially made of PTFE.
