Abstract:

A method and apparatus for obtaining various components of a multi-component material. Generally, a component of a whole blood sample may be concentrated from a patient and re-introduced to the same patient. For example, a clotting component, such as thrombin, from a whole blood sample may be extracted and concentrated in an apparatus and collection to be reapplied or reintroduced into a patient.

Assignee:

Biomet Biologics, LLC - Warsaw IN

International Classification:

B01D 21/26

US Classification:

2103801, 2103601, 210782, 210789, 494 2, 494 5, 422559, 422550, 422533, 422548

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.
