Abstract: A multi-station hydrodynamic catheter includes an outer catheter having a first lumen, the outer catheter having a plurality of orifice stations positioned along a portion of the outer catheter, where each orifice station includes one or more orifices extending from an outer catheter external surface to the first lumen. The multi-station hydrodynamic catheter includes an inner catheter having a second lumen, the inner catheter movable within the first lumen and includes at least one emanator, where the at least one emanator includes one or more fluid delivery ports extending from an inner catheter external surface to the second lumen.
