Abstract: The present invention is a bone growth stimulating and promoting cytokine type biological implant preferably comprising PTH coated with a controlled release biodegradable coating that is implanted preferably in the concave side of a scoliotically curved spine in combination with a bone growth inhibiting type biological implant preferably comprising methotrexate or like anti-metabolite coated with a controlled release biodegradable coating that is implanted preferably in the convex side of a scoliotically curved spine. The insertion of the biological implant is highly non-invasion, especially as compared to more conventional spine surgical methods, and the biological implant does not decrease spinal mobility or spinal range of motion.

Abstract: A tissue mincer includes a canister defining a chamber and an opening, a lid configured to cover the opening, and a tissue cutter. The tissue cutter includes a shaft and a blade assembly. The shaft includes a proximal portion that is configured to be rotated and a distal portion extending into the chamber when the tissue mincer is assembled. The distal portion is coupled to the blade assembly. The blade assembly includes a first disk, at least one blade spaced from the distal portion of the shaft by the first disk, and a disk retainer that encloses at least a portion of the blade. The blade can rotate relative to at least the first disk when the proximal portion of the shaft rotates. The blade includes at least one cutting edge that is configured to cut tissue as the blade rotates.
