A device comprising a trocar having a first end and comprising a cannulation and at least one fenestration proximal the first end; and a housing comprising a first port configured for the attachment of a first syringe and a second port configured for the attachment of a collection vessel, a first valve configured to selectively permit fluid flow through the cannulation of the trocar to the first port, and a second valve configured to selectively permit fluid flow through the cannulation of the trocar to the second port. The device allows the first syringe to draw up bone marrow in small volumes with high vacuum and then transfer the small draws into the collection vessel. The device may increase the recovery of desired cells residing in the bone marrow to be recovered during a bone marrow aspiration procedure.
The present invention provides devices and methods for concentrating a fluid and for treating a patient with the concentrated fluid. The concentrator apparatus includes a main housing (12) defining a separation chamber (14), a filter housing (48) containing a filter (46) comprising a filter element, a piping (44) for moving concentrated fluid from the separation chamber to the filter, and ports (32) for pressurizing the concentrated fluid past the filter element of the filter. The present invention also provides a variety of uses of concentrated body fluids, including autologous concentrated body fluid. The concentrated fluids can be used for example in surgical applications, including graft applications such as allograft, xenograft and autograft applications.

Medical services, namely, concentrating autologous adult stem cells from autologous tissue for tissue regeneration and/or bone fusion in orthopedics, delivering autologous adult stem cells for tissue regeneration and/or bone fusion orthopedics, multi-cell procurement, namely, adipose tissue or bone marrow derived cells for use with tissue regeneration and/or bone fusion orthopedics, harvesting adult stem cells during spinal procedures, and concentrated delivery of adult stem cells for tissue regeneration and/or bone fusion orthopedics
A fluid concentrator includes a main housing and a cartridge removably engaged to the main housing. The main housing includes a first end portion having a first port and a second port, an oppositely disposed second end portion and a separation chamber that extends between the first and second end portions. The second end portion has an inlet port and defines a cartridge passage that extends through the second end portion. The separation chamber is in fluid communication with the inlet port. The cartridge includes a first axial end portion that is engaged with the first end portion and an oppositely disposed second axial end portion, a portion of the second axial end portion is disposed in the cartridge passage of the second end portion of the main housing. The cartridge is adapted to filter fluid from the separation chamber.

A concentrator is used for concentrating a fluid, particularly a plasma component out of blood, for treatment of a patient. The concentrator apparatus includes a main housing defining a centrifuge chamber, that also holds the filter. The concentrator allows viewing of the fluid after centrifuging, with an outlet port positionable at a height corresponding to the level of the fraction of the fluid to be further concentrated. Once the fluid is centrifuged, a portion of the fluid is drawn through the outlet, and then pressured past the filter to further concentrate the fluid using the same vessel as used for centrifuging. The same plunger is preferably used to draw centrifuged fluid from the centrifuge chamber as to pressure the centrifuged fluid past the filter.
