BIFURCATION CATHETER ASSEMBLY WITH DISTALLY MOUNTED SIDE BALLOON AND METHODS

摘要

A catheter assembly and related methods directed to a main balloon and a side balloon, wherein the side balloon is coupled in fluid communication with the main balloon at a location distal of the side balloon. In one example, a side inflation member couples the side balloon in fluid communication to the main balloon at a distal end portion of the main balloon. A side catheter branch of the catheter assembly, which defines a side guidewire lumen, can be operatively mounted to the side balloon at a side balloon connection point to help maintain alignment of the side catheter branch relative to the side balloon.
