Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
95 words
A method of grafting human tissue comprising the steps of removing human bone tissue from a first location in a human body, forming a cavity in a bone at a second location in a human body, compressing the human bone tissue removed from the first location into a plug, positioning the plug of human bone tissue into the cavity formed in the bone at the second location in a human body, and sealing an entrance to the cavity formed in the bone at the second location with the human bone tissue packed in the cavity.
Claim 2
Independent Claim
95 words
A method of grafting human tissue comprising the steps of removing human bone tissue from a first location in a human body, forming a cavity in a bone at a second location in a human body, compressing the human bone tissue removed from the first location into a plug, positioning the plug of human bone tissue into the cavity formed in the bone at the second location in a human body, and sealing an entrance to the cavity formed in the bone at the second location with the human bone tissue packed in the cavity.
Claim 3
Dependent Claim
34 words
A method as set forth in claim 1 wherein said step of sealing an entrance to the cavity includes forming a seal in situ by injecting flowable material into the entrance to the cavity.
Claim 4
Independent Claim
78 words
A method of grafting human tissue comprising the steps of obtaining a quantity of human bone fragments, compressing the human bone fragments from a first volume to a second volume which is less than the first volume, forming a cavity in a human bone, positioning the human bone fragments in the cavity in the human bone, maintaining the human bone fragments in a compressed condition while the human bone fragments are in the cavity in the human bone.
Claim 5
Independent Claim
78 words
A method of grafting human tissue comprising the steps of obtaining a quantity of human bone fragments, compressing the human bone fragments from a first volume to a second volume which is less than the first volume, forming a cavity in a human bone, positioning the human bone fragments in the cavity in the human bone, maintaining the human bone fragments in a compressed condition while the human bone fragments are in the cavity in the human bone.
Claim 6
Independent Claim
95 words
A method of grafting tissue comprising the steps of obtaining a quantity of bone fragments, compressing the bone fragments from a first volume to a second volume which is less than the first volume, forming a cavity in a human bone, positioning the bone fragments in the cavity in the human bone, maintaining the bone fragments in a compressed condition while the bone fragments are in the cavity in the human bone, and sealing an entrance to the cavity in the human bone while the bone fragments are in the cavity in a compressed condition.
Claim 7
Independent Claim
95 words
A method of grafting tissue comprising the steps of obtaining a quantity of bone fragments, compressing the bone fragments from a first volume to a second volume which is less than the first volume, forming a cavity in a human bone, positioning the bone fragments in the cavity in the human bone, maintaining the bone fragments in a compressed condition while the bone fragments are in the cavity in the human bone, and sealing an entrance to the cavity in the human bone while the bone fragments are in the cavity in a compressed condition.
