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.
