Abstract:
A rotational neuro thrombectomy catheter, comprising:an elongate flexible tubular body, having a proximal end and a distal end, the tubular body having a distal segment with an outside diameter small enough to access the M1 segment of the middle cerebral artery and sufficiently kink-resistant to enable rotation of a rotatable tip therein; a rotatable element extending through the body; a rotatable tip at the distal end of the body and connected to the rotatable element; a control on the proximal end of the body; at least one radially inwardly extending stationary cutting member on the tubular body; and at least one radially outwardly extending flange on the rotatable tip for cooperating with the stationary cutting member to cut material drawn into the tubular body.
