Abstract:

A dynamic extension splint is provided which has a pair of elongated strut assemblies which each include a pivotal joint. Each strut assembly is removably supported on one side of a strut support unit which operates to mount the strut assemblies on a body member in alignment with a body joint. A strut assembly includes first and second elongated strut members which are flat units which extend from a pivotal joint. This joint connects one end of the first and second strut members for pivotal movement about one or more pivot axes, and a bias unit mounted at the joint opposes pivotal movement of the strut members in one direction and aids such pivotal movement in a second opposite direction. The bias of this bias unit is adjustable by a bias adjustment mechanism also located at the pivotal joint.

Abstract:

The instant invention is directed to a mammary prosthesis injector. The injector comprises a hollow tube having an opening at one end thereof. A bag for holding the prosthesis and reducing friction between the tube and the prosthesis is located, in part, within the tube. A mechanism for pulling the bag from within the tube is slidably mounted on the exterior of the tube and engages the bag. The prosthesis, which is held within the bag which is within the tube, is ejected from the tube and through the opening when the pulling mechanism is slid along the exterior of the tube.
