1. A medical device, comprising:
a catheter body having a proximal portion, a distal portion and a lumen extending therein;
a tubular member positioned within the lumen of the catheter body;
a fluid jet emanator positioned within the lumen of the catheter body, the fluid jet emanator coupled to a distal end region of the tubular member, wherein the catheter body further comprises an inflow orifice formed through a wall of the catheter body adjacent to the fluid jet emanator;
a balloon disposed along the catheter body and positioned distally of both the inflow orifice and the fluid jet emanator;
wherein the fluid jet emanator includes one or more distally-directed jet orifices; and
wherein the distally-directed jet orifices are configured to provide for automatic inflation of the balloon.
