ABSTRACT:
A catheter (10) for use with a guidewire (40) includes an elongated, flexible body (12a) defining distal and proximal ends, and also defining a balloon inflation lumen (14) extending therethrough. A balloon (24) is affixed near the distal end, at a location selected so that an extending portion (12b) of the catheter extends distally beyond the balloon. A guidewire retaining arrangement (30) is located on an exterior part of the extending portion (12b) of the catheter, for allowing the catheter to slide relative to the guidewire, while being maintained adjacent thereto. In a particular embodiment of the invention, the balloon (24) has a perfusion channel (22) extending from a distal side (16) of the balloon to the proximal side. The perfusion channel may have walls which have different compliance than the remainder of the balloon. In an embodiment with a lobed balloon (724), the guidewire retaining arrangements are located so as to direct the guidewire between the lobes of the balloon.
