A percutaneous tissue removal apparatus including 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.
A method of harvesting and utilizing a human patient's body tissue, said method comprising the steps of cutting tissue at a first location in a patient's body, removing cut tissue from the patient's body during performance of said step of cutting tissue, said step of removing cut tissue from the patient's body including utilizing suction to move cut tissue from the first location in the patient's body to a location outside of the patient's body during performance of said step of cutting tissue, compacting the cut tissue to decrease the volume of a mass of the cut tissue from a first volume to a second volume which is smaller than the first volume, and thereafter, inserting the compacted cut tissue into an opening formed at a second location in the patient's body.
A method of harvesting and utilizing a human patient's body tissue, said method comprising the steps of cutting particles of tissue from a first location in a patient's body, conducting a flow of tissue particles from the first location in the patient's body to a location outside of the patient's body during performance of said step of cutting tissue, conducting a flow of the tissue particles into an opening at a second location in the patient's body, packing the tissue particles into the opening at the second location in the patient's body, and sealing the opening at the second location by conducting a flow of sealant material into the opening at the second location to mold a plug of sealant material in the opening at the second location with the sealant material engaging the tissue particles and blocking movement of the tissue particles out of the opening at the second location in the patient's body.
A method of harvesting and utilizing a human patient's tissue, said method comprising the steps of cutting particles of tissue from a first location in a patient's body, conducting a flow of tissue particles from the first location in the patient's body during performance of said step of cutting tissue, enclosing tissue particles from the flow of tissue particles from the first location in the patient's body in a sac, and, thereafter, inserting the sac of tissue particles into an opening formed at a second location in the patient's body.
