Abstract
An apparatus for deploying a guidewire across a complex lesion in a vessel formed by a wall and normally having a lumen extending therethrough including an elongate flexible catheter having proximal and distal extremities and having a plurality of separate spaced apart lumens therein extending from the proximal extremity into a location at least adjacent the distal extremity. A handle is mounted on the proximal extremity of the flexible elongate catheter. A flexible elongate sheath is mounted on the catheter and has a proximal portion, a transition portion and a distal portion with the transition portion being in the vicinity of the distal extremity of the catheter. The sheath has a lumen therein extending from the proximal portion through the transition portion and through the distal portion. First and second devices are slidably mounted in the spaced-apart lumens of said catheter. The lumen in the distal portion of said sheath has a size so that it can accommodate only one at a time of the at least two devices.
