Method for utilizing human tissue
First Claim
1. A method of using human tissue, said method comprising the steps of removing blood from a human patient, centrifuging the blood removed from the human patient to at least partially remove a component from the blood, placing tissue graft material and the component from the blood into a mold, pressing at least one of the tissue graft material and the component from the blood in the mold to form an implant, removing the implant from the mold, and implanting the implant in the patient from which the blood was removed.

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.

9. A method of using human tissue, said method comprising the steps of removing blood from the human patient, centrifuging blood removed from the human patient to at least partially remove one or more components from the blood, and implanting in the patient a blood component remaining after centrifliging the blood, wherein said step of implanting a blood component in the patient includes moving a biodegradable bag into the patient.
- 10. A method of using human tissue, said method comprising the steps of removing tissue from a first location in a human patient, and implanting at least a portion of the tissue at a second location in the human patient, said step of implanting at least a portion of the tissue at a second location in the human patient includes moving a biodegradable bag to the second location in the human patient.

15. A method of utilizing human tissue, said method comprising the steps of:
-
percutaneously harvesting tissue from bone of a human donor; conveying the harvested tissue to a location outside the body of the donor through a sterile passage; collecting the harvested tissue in a container operatively associated with the sterile passage; placing tissue graft material and the harvested tissue in a form; pressing at least one of the tissue graft material and harvested tissue in the font to create a tissue graft plug; removing the tissue graft plug from the form; and implanting the tissue graft plug into a human recipient. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method of utilizing human tissue, said method comprising the steps of:
-
harvesting tissue from a human patient; removing blood from the harvested tissue; separating a blood component from the removed blood; combining the blood component with the harvested tissue to form an implant; and implanting the implant into the human patient, wherein prior to implantation the implant is compressed in a mold. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39)
