The embodiments presented herein relate to concepts designed to eliminate the gap between a catheter and guide wire that can otherwise contribute to a catheter getting stuck within the vasculature. In an example embodiment, a microcatheter with an enlarged distal section is described. The enlarged portion of the microcatheter may be located close to the inner diameter of the guide catheter in order to reduce any open space between the microcatheter and the guide catheter, and the guidewire can be placed through the microcatheter and used to guide the system. The microcatheter can include one or more marker bands to aid in aligning the microcatheter correctly relative to the guide catheter. After the guide catheter and microcatheter are tracked to the appropriate treatment site, the microcatheter can then be used to deploy various medical devices to treat a patient.

Intravascular treatment site access

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.
