Abstract
The designs and methods disclosed herein are for 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. The distal mouth of the tip can be beveled at an angle inclined from the longitudinal axis of the shaft. The braided tip can be braced with a reinforcing ring which can be welded or overmolded to the distal end of the braid and prevents the tip from collapsing under aspiration forces. The reinforcing ring can have relief features positioned to allow the oblique orientation of the ring to maintain a circular inner channel when the tip is compressed and delivered through a guide sheath and expanded at a target site. The distal tip can be expanded to a profile that is either symmetric or asymmetric with the catheter shaft.
