Abstract
A convertible catheter assembly for performing an intravascular procedure incorporates a guide wire lumen having at least a proximal segment thereof manufactured from a collapsible tubular member. The catheter assembly includes a full length guide wire lumen and an intermediate guide wire port therein so that the catheter may be utilized in a single operator exchange or an over-the-wire mode. The collapsible proximal segment of the guide wire lumen decreases the overall profile of the catheter by collapsing radially inward when not in use during a single operator exchange procedure.
