Abstract: A corrosion resistant connection system including a base structure, a threaded orifice in the base structure, a seal about the threaded orifice and a threaded stud with a distal end, a proximal end, and an intermediate shoulder defining a sealing surface opposing a support surface. The distal end of the threaded stud is received in the orifice of the base structure driving the sealing surface of the shoulder to engage the seal to prevent corrosion of the threaded orifice, while maintaining electrical continuity. A terminal is disposed about the proximal end of the threaded stud seated on the support surface of the shoulder. A threaded nut is disposed about the proximal end of the stud engaging the terminal.

Abstract: A therapeutic method for treating pressure ulcers like decubitus ulcers with biodegradable collagen flake compositions and with biodegradable collagen sponge or sponge-like compositions. The products of the invention includes biodegradable collagen flake compositions and biodegradable collagen sponge or sponge-like compositions. The products are useful for medical applications, like skin reconstruction, treatment of wounds, especially deep wounds, also in connection with surgery, including cosmetic surgery. The invention also deals with biocompatible synthetic resin sponge or sponge-like and flake products for medical and similar applications. The invention contemplates the treatment of human and animal species.
