WHAT IS CLAIMED IS:

1. A filter for separating blood components, comprising:

a first pleated wall having a collection end; and

a second pleated wall converging with said first pleated wall at said collection end, wherein said first pleated wall and said second pleated wall are each composed of a material that is porous and configured as a barrier to red blood cells.

2. The filter according to claim 1, wherein said first pleated wall and said second pleated wall each include a pleated surface having a plurality of pleats formed thereon.

3. The filter according to claim 2, wherein each of said plurality of pleats has a length that extends in a direction towards said collection end.

4. The filter according to claim 1, wherein said first pleated wall and said second pleated wall form an angle of convergence relative to each other at said collection end.

5. The filter according to claim 4, wherein said angle of convergence is between approximately 0.1 to 2.5 degrees.

6. The filter according to claim 1, wherein said second wall has a joining end opposite said collection end.

7. The filter according to claim 6, further including a third pleated wall connected to said joining end, said third pleated wall being porous and configured as a barrier to red blood cells.

8. The filter according to claim 6, wherein said filter has a top and a bottom, said joining end defining said top and said collecting end defining said bottom.

9. The filter according to claim 1, wherein said material is permeable to at least one of saline solution, glucose, sodium pyruvate, inosine, adenine, dibasic sodium phosphate and monobasic sodium phosphate.

10. The filter according to claim 8, wherein said material is at least one of a filter paper and a membrane.

11. The filter according to claim 1 , wherein said first pleated wall and said second pleated wall converge to form a V-shaped filter.

12. A blood separation device, comprising:

a vessel;

a blood inlet formed in said vessel; and

a pleated filter placed within said vessel, said pleated filter separating said vessel into an inlet chamber fluidly connected to said blood inlet and a filtrate chamber, said pleated filter being porous and configured as a red blood cell barrier between said inlet chamber and said filtrate chamber.

13. The blood separation device according to claim 11, further including a first outlet fluidly connected to said inlet chamber and a second outlet fluidly connected to said filtrate chamber.

14. The blood separation device according to claim 13, wherein said pleated filter includes a first pleated wall and a second pleated wall, said first pleated wall and said second pleated wall converging adjacent to said first outlet.

15. The blood separation device according to claim 14, wherein said material is permeable to at least one of plasma, saline solution, glucose, sodium pyruvate, inosine, adenine, dibasic sodium phosphate and monobasic sodium phosphate.

16. The blood separation device according to claim 14, wherein said vessel has a bottom and said first pleated wall and said second pleated wall form an angle of convergence relative to each other at said bottom.

17. The blood separation device according claim 16, wherein said angle of convergence is between approximately 0.1 to 2.5 degrees.

18. The blood separation device according to claim 16, wherein said first pleated wall and said second pleated wall each have a plurality of pleats formed thereon, each of said plurality of pleats having a length that extends in a direction toward said bottom.

19. A method of collecting red blood cells, comprising:

providing a rejuvenated blood product including red blood cells and a rejuvenating solution;

mixing said rejuvenated blood product with a wash solution to form a washed blood solution;

providing a pleated filter including a first pleated wall with a collection end and a second pleated wall that converges with said first pleated wall at said collection end, said first pleated wall and said second pleated wall being composed of a material that is porous and configured as a barrier to red blood cells;

flowing said washed blood solution on said pleated filter to separate said red blood cells from said rejuvenating solution and said wash solution; and

collecting said separated red blood cells at said collection end.

20. The method according to claim 19, further including the step of removing said separated rejuvenating solution and said separated wash solution from said pleated filter.
