Abstract: A cast comprising a shell of bendable material with opposed ends and opposed edges, the shell being bent into a conical shape that is adapted to surround and form a gap with a part of a patient. The edges are fastened on and sealed to each other, and the cast includes a layer of casting material about the shell. A stretchable membrane is disposed in the gap and sealed on the shell forming a fluid tight bag which when inflated engages the patient's part. Metal particles on the membrane surface opposite the shell produce an oligodynamic effect.

Abstract: Process for a transplantable body part including extracting soluble materials therefrom, contacting the part with ozone, submerging the part in an inert body of liquid, contacting the part with nanoparticles coated with a growth factor or medicinal, and thereafter applying a pressure between 68,000 and 100,000 pounds per square inch to said body of liquid and part for a sufficient time to destroy microorganisms and affix the nanoparticles to the part. Also sterilized body parts with nonoparticles attached thereto, and body parts made by the foregoing processes.
