Abstract: An external custom prosthetic device is created and positioned upon a patient such that an area to be covered is matingly engaged with a product that is a simulacrum of the part desired to be replaced due to reversed imaging, by laser photography or laser mapping. A method for creating a silicone based prosthetic, process for generating same with or without an air pocket disposed therein, and products by these processes are likewise taught.

Abstract: A fastener, for releasably securing movable panels or other components of a support device, includes a clamping member having a cap and an externally threaded shank, a clamping knob internally threaded for movement along the shank, and a retaining member having a threaded shaft received into an internally threaded aperture of the shank. The external shank threads and internal knob threads have a relatively coarse pitch, while the shaft threads and internal aperture threads have a relatively fine pitch. The clamping knob includes a recess with a locking shoulder that engages a head of the retaining member, thus to determine a locked position for the knob, preventing further movement of the knob in the axial direction away from the cap. The locked position can be set to coincide with a clamping position of the knob, or alternatively spaced apart to allow limited axial travel of the knob.
