摘要：
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.
