Apparatus and method for tissue removal
First Claim
1. A surgical procedure to be conducted on a patient, said surgical procedure comprising the steps of removing tissue from a first location in the patient'"'"'s body, separating one or more components from at least a portion of the removed tissue, thereafter packing the removed tissue into a desired shape, and thereafter implanting the packed tissue at a second location in the patient'"'"'s body, wherein the removed tissue includes blood and other body tissue.

Abstract
Percutaneous tissue removal apparatus comprises a flexible drill shaft, a cutting tip mounted on the shaft for placement adjacent a tissue mass for cutting the tissue, means for transmitting motion to the shaft to move the cutting tip against the tissue to cut tissue fragments from the tissue, and means for removing the tissue fragments along the shaft by suction to a location outside the tissue mass while cutting. The apparatus may include means for collecting one or more selected components of the harvested tissue fragments for implantation of the fragments preferably into the body of the patient from whom they were removed. Where the tissue to be cut is bone, a cutting tip is preferably made of a polymeric material which is softer than the cortical portion of the bone, although the cutting tip may be made of a ceramic or a composite material. A second flexible shaft may be provided either within or about the flexible drill shaft. The harvested tissue fragments may be implanted in the donor patient'"'"'s body.

11. A surgical procedure to be conducted on a patient, said surgical procedure comprising the steps of inserting a first tubular member into the patient'"'"'s body, moving body tissue from a first location in the patient'"'"'s body through the first tubular member to a location outside of the patient'"'"'s body, inserting a second tubular member into the patient'"'"'s body, and moving at least a portion of the body tissue through the second tubular member to a second location in the patient'"'"'s body, wherein a substance is added to the body tissue after moving the body tissue from the first location through the first tubular member to a location outside of the patient'"'"'s body and prior to moving the body tissue through the second tubular member;
- wherein the added substance is a bone growth promoter; and
wherein said step separating one or more components from at least a portion of the tissue, wherein said step of moving body tissue from the first location in the patient'"'"'s body through the first tubular member includes moving blood from the first location in the patient'"'"'s body through the first tubular member, and surgical procedure further includes separating one or more components from the blood, said step of moving body tissue through the second tubular member to the second location in the patient'"'"'s body includes moving the blood from which one or more components have been removed through the second tubular member to the second location in the patient'"'"'s body. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
- wherein the added substance is a bone growth promoter; and
- 24. A surgical procedure to be conducted on a patient, said surgical procedure comprising the steps of cutting body tissue at a first location in a patient'"'"'s body, moving blood and other body tissue along a first tubular member in a direction away from the first location in the patient'"'"'s body to a location outside of the patient'"'"'s body, separating one or more components from at least one of the blood and other body tissue at a location outside of the patient'"'"'s body, thereafter, packing the blood and other body tissue to form a packed tissue mass, moving the packed tissue mass along a second tubular member in a direction toward a second location in the patient'"'"'s body, and implanting the packed tissue mass at the second location in the patient'"'"'s body.
- 30. A surgical procedure to be conducted on a patient, said surgical procedure comprising the steps of cutting body tissue at a first location in a patient'"'"'s body, moving blood and other body tissue along a first tubular member in a direction away from the first location in the patient'"'"'s body to a location outside of the patient'"'"'s body, separating one or more components from at least one of the blood and other body tissue at a location outside of the patient'"'"'s body, thereafter, moving the blood and other body tissue along a second tubular member in a direction toward a second location in the patient'"'"'s body, and implanting the blood and other body tissue at the second location in the patient'"'"'s body wherein said step of separating one or more components from at least one of the blood and other body tissue includes centrifuging the other body tissue.
