摘要： A hydrodynamic catheter includes a catheter body with a catheter lumen and an infusion tube extending within the catheter body, the infusion tube configured for coupling with a fluid source near the catheter proximal portion. An inflow orifice and an outflow orifice are positioned at locations along a catheter body perimeter. A fluid jet emanator is in fluid communication with the infusion tube, where the fluid jet emanator includes one or more jet orifices configured to direct one or more fluid jets through the catheter lumen from near the inflow orifice toward the outflow orifice. A pivot cylinder located along the catheter body perimeter is positioned distal relative to one or more of the fluid jet emanator, the inflow orifice, or the outflow orifice.
