The invention disclosed herein provides a catheter that acts as both a rapid-exchange (RX) catheter and a multi-exchange (MX) catheter. The catheter includes a proximal shaft, transition shaft, distal shaft, and catheter conversion shaft. Attached to the distalmost tip of the conversion shaft is a clip. The clip allows the conversion shaft to be detachably secured to the transition shaft while the catheter and a guidewire are both in situ. When the clip attaches to the transition shaft, a clip port in the clip aligns with an exchange joint in the transition shaft. In doing so, the catheter conversion shaft and a guide member act to allow the guidewire to be accessible through a guidewire exit of the guide member. The guide member is slidable along the catheter conversion shaft such that the catheter is usable as a MX catheter.
