Method for removing material from a patient's body
First Claim
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.

Abstract
The invention comprises a method for removal of bone marrow tissue from a patient'"'"'s body. The method generally comprises the steps of providing an apparatus comprising an elongate member for receiving bone marrow tissue. The elongate member defines a lumen and comprises a distal end defining an aperture and a proximal end. The apparatus further comprises an elongate tissue removal member for conveying bone marrow tissue through the lumen. The tissue removal member is rotatably disposed within the lumen. The method further comprises gathering a sample of said tissue into said lumen; and conveying with said tissue removal member at least a portion of the tissue sample proximally along said lumen. The step of gathering may be accomplished by advancing the apparatus through the tissue.

15. A method for removing bone marrow from a patient'"'"'s body, comprising the steps of:
-
providing a tissue removal 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 tissue 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 and helical projections disposed about the shaft between the proximal and the distal end that also forms a distal end of the tissue removal member, 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; advancing the elongate member through a region of a patient'"'"'s body containing bone marrow, so that bone marrow tissue is at least substantially gathered into said lumen; and conveying at least a portion of the bone marrow at least substantially gathered into said lumen away from said region of the patient'"'"'s body containing bone marrow. - View Dependent Claims (16)
