1. A system for separating and extracting selected fractions from a container, the system comprising:
- a container to contain the whole material; and
a separation system operable to be positioned within the container, including;
a first separation member;
a second separation member;
a third separation member operably interconnecting said first separation member and said second separation member; and
a check valve positioned relative to the second separation member that allows for movement of a material past said second separation member through a checked passage defined between said third separation member and said second separation member;
wherein each of said first member, said second member, and said third member of the separation system is at least partially fixed at a position relative to each other of said first member, said second member, and said third member of the separation system; and
wherein said third separation member allows access to a volume defined between said first separation member and said second separation member.

Abstract
An apparatus that allows for separating and collecting a fraction of a sample. The apparatus, when used with a centrifuge, allows for the creation of at various fractions in the apparatus. A buoy system that may include a first buoy portion and a second buoy member operably interconnected may be used to form at least three fractions from a sample during a substantially single centrifugation process. Therefore, the separation of various fractions may be substantially quick and efficient. Also selected fractions from the sample can be applied to a patient, either alone or as part of a mixture.

16. A system for separating and extracting selected fractions from a container, the system comprising:
-
a container to contain the whole material; and a separation system positioned within said container, including; a first separation member; a second separation member; a third separation member operably interconnecting said first separation member and said second separation member, wherein said third separation member includes a passage extending into at least a portion of a dimension of said third separation member; and a check valve positioned relative to said third separation member to selectively seal a checked passage formed relative to said first separation member to allow for movement of a material relative to said first separation member; wherein the first separation member is fixed relative to the second separation member; wherein said passage of said third separation member allows access to a volume defined between said first separation member and said second separation member; wherein said check valve allows for passage of a selected material upon the application of a force through said checked passage; wherein said check valve is operable to open said checked passage upon the application of a vacuum to withdraw a material from between said first separation member said second separation member through said passage in said third separation member.

17. A system for separating and extracting selected fractions from a container, the system comprising:
-
a container to contain the whole material; and a separation system positioned within said container, including; a first separation member; a second separation member; a third separation member operably interconnecting said first separation member and said second separation member, wherein said third separation member includes a passage extending at least a portion of a dimension of said third separation member; and a check valve positioned relative to said third separation member to selectively seal a checked passage formed relative to said first separation member to allow for movement of a material relative to said first separation member; wherein the first separation member is fixed relative to the second separation member; wherein said passage of said third separation member allows access to a volume defined between said first separation member and said second separation member; wherein said check valve allows for passage of a selected material upon the application of a force through said checked passage; wherein said check valve includes a flexible member having a portion to engage said first separation member to seal said checked passage. - View Dependent Claims (18, 19)

20. A method for separating and extracting selected fractions from a container, comprising:
-
centrifuging a container with a separation system therein, the separation system having a first separation member, a second separation member, and a third separation member to form a fraction of a whole material between the first separation member and the second separation member; wherein a check valve selectively seals a checked passage formed between said first separation member and said third separation member and allows movement of at least a portion of the whole material past said first separation member; wherein said third separation member is interconnecting said first separation member and said second separation member and said first separation member is fixed relative to said second separation member; wherein access to a volume between said first separation member and said second separation member is allowed through said third separation member. - View Dependent Claims (21, 22)
