Abstract
A method of reducing cell damage can include inserting device into a blood vessel, wherein the device includes a hollow shaft, a lumen, a fluid directing portion comprising a U-shaped lateral orifice extending between the exterior and interior surfaces and a corresponding U-shaped diverter adjacent to the U-shaped lateral orifice, wherein the diverter is disposed within the lumen and transverse to the central axis, and decreasing free plasma hemoglobin levels, thereby reducing damage to circulating blood cells or endothelium during dialysis.

A method of reducing cell damage comprising:
- inserting a dialysis needle into a blood vessel, wherein the dialysis needle includes
- a hollow shaft extending from an open proximal end to an open distal end, the shaft having an exterior surface, an interior surface, a lumen, and a central axis,
- a fluid directing portion comprising a U-shaped lateral orifice extending between the exterior and interior surfaces and a corresponding U-shaped diverter adjacent to the U-shaped lateral orifice,
- wherein the diverter is disposed within the lumen and transverse to the central axis,
- and
- decreasing free plasma hemoglobin levels, thereby reducing damage to circulating blood cells or endothelium during dialysis.

- decreasing free plasma hemoglobin levels, thereby reducing damage to circulating blood cells or endothelium during fluid delivery.
A method of decreasing the velocity and turbulence of fluid exiting a device comprising:
- flowing fluid through an opening in a device, wherein the device includes
- a hollow shaft extending from an open proximal end to an open distal end, the shaft having an exterior surface, an interior surface, a lumen, and a central axis,
- a fluid directing portion comprising a U-shaped lateral orifice extending between the exterior and interior surfaces and a corresponding U-shaped diverter adjacent to the U-shaped lateral orifice,
- wherein the diverter is disposed within the lumen and transverse to the central axis.
