US Patent 9402981 Subintimal re-entry catheter and retrograde recanalization

A catheter for recanalizing a blood vessel having an occlusion therein via a subintimal pathway. The catheter includes a catheter shaft having an inflatable balloon mounted to the distal end portion of the catheter shaft. A flexible tubular member extends from the catheter shaft and along an exterior of the inflatable balloon. Inflation of the inflatable balloon deflects the flexible tubular member into a deflected configuration away from a longitudinal axis of the catheter shaft to effect re-entry into the true lumen distal of the occlusion.
