ABSTRACT:
The shaft of a dilation balloon catheter includes three lumens; a dilation balloon lumen, a guidewire lumen, and an inner balloon lumen. A dilation balloon near the distal near the distal end of the catheter is inflated and deflated through the dilation balloon lumen. An inner balloon within the guidewire lumen provides a means for releasably securing a guidewire disposed within the guidewire lumen, thereby allowing the catheter to be configured as a fixed-wire catheter and an over-the-wire catheter. The inner balloon is inflated and deflated through the inner balloon lumen. A longitudinally-extending separable area in the wall of the guidewire lumen allows the guidewire to pass transversely therethrough, thereby allowing the catheter to be removed from a patient while leaving the guidewire in place within the patient. A method for constructing the shaft is also provided.
