Direct stream hydrodynamic catheter system

A hydrodynamic catheter, comprising:

• a catheter body including a proximal portion, a distal portion and a lumen extending therein;
• a high pressure tube positioned within a lumen of the catheter body;
• a fluid jet emanator positioned within the lumen of the catheter body, wherein the fluid jet emanator is attached to a distal end region of the high pressure tube;
• an expandable balloon disposed along the catheter body, wherein the expandable balloon is positioned proximal of the fluid jet emanator;
• an inflow orifice positioned in the sidewall of the catheter body, the inflow orifice positioned between the expandable balloon and the fluid jet emanator;
• and
• an outflow orifice positioned in the sidewall of the catheter body adjacent to the fluid jet emanator.
