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.
Claims24
A catheter system comprising:
- a multi-station hydrodynamic catheter including:
- an outer catheter having a first lumen, the outer catheter having a plurality of orifice stations positioned along a portion of the outer catheter, wherein each orifice station includes one or more orifices extending from an outer catheter external surface to the first lumen;
- and
- an inner catheter having a second lumen, the inner catheter movable within the first lumen and includes at least one emanator, wherein the at least one emanator includes one or more fluid delivery ports extending from an inner catheter external surface to the second lumen,
- the inner catheter movable within the first lumen between a first orifice station and a second orifice station of the plurality of orifice stations,
- wherein at the first orifice station, the one or more fluid delivery ports of the emanator are in fluid communication with the one or more orifices of the first orifice station of the plurality of orifice stations, and at the second orifice station, the one or more fluid delivery ports of the emanator are in fluid communication with the one or more orifices of a second orifice station of the plurality of orifice stations, the second orifice station positioned distally relative to the first orifice station, and
- wherein the one or more orifices at the first orifice station are configured to generate a first fluid jet and the one or more orifices at the second orifice station are configured to generate a second fluid jet distal to the first fluid jet.

A catheter system comprising:
- a multi-station hydrodynamic catheter, including:
- an outer catheter having a first lumen, the outer catheter having a plurality of orifice stations positioned along a portion of the outer catheter, wherein each orifice station includes one or more orifices extending from an outer catheter external surface to the first lumen;
- and
- an inner catheter having a second lumen, the inner catheter movable within the first lumen and includes a fluid reservoir, the fluid reservoir in fluid communication with the second lumen,
- the inner catheter movable within the first lumen, between first and second orifice stations of the plurality of orifice stations,
- wherein at the first orifice station, the fluid reservoir is in fluid communication with the one or more orifices of the first orifice station, and at the second orifice station, the fluid reservoir is in fluid communication with the one or more orifices of the second orifice station, the second orifice station distal to the first orifice station, and
- wherein the fluid reservoir at the first orifice station generates a first fluid jet through the one or more orifices when supplied with a pressurized fluid, and the fluid reservoir at the second orifice station generates a second fluid jet through the one or more orifices when supplied with a pressurized fluid distal to the first fluid jet.
