1. A method for removing bone marrow from a patient's body, comprising the steps of: providing an apparatus comprising an elongate member for receiving said bone marrow, said elongate member defining a lumen and comprising a distal end defining an aperture and a proximal end, the apparatus further comprising an elongate tissue removal member for conveying bone marrow through said lumen, said tissue removal member being rotatably disposed entirely within said lumen so that no portion of the tissue removal member extends through the aperture, said tissue removal member having a shaft with a proximal end, a distal end that also forms a distal end of the tissue removal member, and helical projections disposed about the shaft between the proximal and the distal end, the distal end of the shaft being recessed proximally relative to said aperture when said tissue removal member is fully disposed within said lumen so that none of the tissue removal member protrudes from the lumen via the aperture; gathering a sample of said bone marrow into said lumen; and conveying with said tissue removal member at least a portion of the bone marrow proximally along said lumen.
