System for delivering a catheter (20) to a location of interest in the vasculature, with a guidewire (30) selectively positioned at the location, a self-expanding sheath (10) being positioned within a lumen of the catheter (20), the catheter (20) and the self-expanding sheath (10) being advanceable in tandem over the guidewire (30), wherein distally moving a distal end of the self-expanding sheath (10) out from an inner lumen of the catheter (20) causes the self-expanding sheath (10) to move from a collapsed state within the catheter (20) to an expanded state outside the catheter (20). |
