  • Intravascular treatment site access
    Patent number: 10682493
    Abstract: A device and its method of use eliminates or reduces the gap between a catheter and guide wire that can otherwise contribute to a catheter getting stuck within the vasculature. The device is maintained at or near the distal end of the catheter while being advanced through the vessels of a patient. The reduced gap size prevents the catheter from otherwise “catching” on various structures of a vessel, such as a bifurcation.
