Abstract
A clot retrieval catheter with a large bore shaft and a distal braid-supported tip that is expandable to a diameter larger than the outer sheath through which it is delivered is described herein. The shaft can have a plurality of supporting braids fixed distally to a radiopaque marker band. The tip can have another plurality of supporting braids fixed proximally to the marker band and a decreasing braid angle distally so that the tip can be heat set to an expanded funnel shape. The wires of the tip braids can follow one spiral direction distally and then invert proximally back on themselves to form the other spiral direction of the braid. This inversion of the wires results in atraumatic distal hoops at the distal termination of the braid. Designs can further have spines capable of resisting elongation of the catheter shaft during a procedure.
