Abstract
Abstract Percutaneous tissue removal apparatus include a flexible drill shaft, a cutting tip mounted on the shaft for cutting tissue, structure for transmitting motion to the shaft to cut tissue fragments from the tissue, and structure for removing the tissue fragments along the shaft by suction to a location outside the tissue mass while cutting. The apparatus may include structure 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. The tissue fragments may be inserted in a biogradable sac and then placed in an opening in a patient's body. Alternatively, the fragments may be placed in the opening and thereafter sealed with a biogradable or polymeric material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
91 words
A method of grafting human tissue, said method comprising the steps of inserting human body tissue particles into at least a portion of an opening in a human body, and, thereafter, sealing the portion of the opening in the human body in which the human body tissue particles are disposed by conducting a flow of a sealant material into a portion of the opening in the human body which is disposed outward of the portion of the opening in the human body in which the human body tissue particles are disposed.
Claim 2
Independent Claim
91 words
A method of grafting human tissue, said method comprising the steps of inserting human body tissue particles into at least a portion of an opening in a human body, and, thereafter, sealing the portion of the opening in the human body in which the human body tissue particles are disposed by conducting a flow of a sealant material into a portion of the opening in the human body which is disposed outward of the portion of the opening in the human body in which the human body tissue particles are disposed.
Claim 3
Dependent Claim
62 words
A method as set forth in claim 1 wherein said step of inserting human body tissue particles into at least a portion of an opening in a human body includes conducting a flow of human body tissue particles into the opening in a human body and compacting the human body tissue particles while they are in the opening in the human body.
Claim 4
Dependent Claim
51 words
A method of grafting human body tissue as set forth in claim 1, wherein said step of sealing the portion of the opening in the human body in which the human body tissue particles are disposed includes forming a plug of sealant in situ in the opening in the human body.
Claim 5
Independent Claim
71 words
A method of grafting human tissue, said method comprising the steps of compacting human body tissue particles by applying pressure against the human body tissue particles and removing fluid from the human body tissue particles while performing said step of compacting the human body tissue particles, enclosing the human body tissue particles in a sac, and inserting the sac of human body tissue particles into an opening in a human body.
Claim 6
Independent Claim
71 words
A method of grafting human tissue, said method comprising the steps of compacting human body tissue particles by applying pressure against the human body tissue particles and removing fluid from the human body tissue particles while performing said step of compacting the human body tissue particles, enclosing the human body tissue particles in a sac, and inserting the sac of human body tissue particles into an opening in a human body.
Claim 7
Dependent Claim
40 words
A method as set forth in claim 4 wherein said step of enclosing the human body tissue particles in a sac includes enclosing material other than human body tissue particles in the sac along with the human body tissue particles.
Claim 8
Dependent Claim
34 words
A method as set forth in claim 4 wherein said step of compacting human body tissue is performed prior to performance of said step of enclosing the human body tissue particles in a sac.
