1. A bone marrow aspiration device, comprising:
- an elongate penetrating element having a proximal end, a distal end, and an inner lumen extending therebetween;
a chamber in communication with the proximal end of the elongate penetrating element, the chamber being adapted to removably retain a substrate; and
a fluid extraction mechanism in communication with the chamber, the fluid extraction mechanism being effective to pull fluid through the elongate penetrating element into the chamber and through the substrate.

Abstract
Bone marrow aspiration devices and methods are disclosed for use in preparing a substrate. In general, the device includes an elongate penetrating element, a chamber adapted to retain a substrate, and a fluid extraction mechanism that is effective to pull fluid through the elongate penetrating element, into the chamber, and through the substrate. The device is particularly advantageous in that it will allow for the removal of fluids from a patient'"'"'s body and the preparation of a substrate in a single process, thereby providing a more efficient method and device for preparing a substrate.

31. A method for preparing a substrate, comprising:
-
providing a bone marrow aspirator device having an elongate penetrating element having a proximal end, a distal end adapted to penetrate bone, and an inner lumen extending therebetween, a chamber in fluid communication with the proximal end of the elongate penetrating element, a substrate disposed within the chamber, and a fluid extraction mechanism effective to pull fluid through the elongate penetrating element, into the chamber, and through the substrate;
penetrating the distal end of the elongate penetrating element into a patient;
actuating the fluid extraction mechanism to pull fluid from the patient through the elongate penetrating element, into the chamber, and through the substrate, thereby concentrating cells from a biological material within the substrate. - View Dependent Claims (32, 33, 34, 35)
