A waterproof composite material that comprises three layers, a top layer, a middle layer, and a bottom layer. The middle layer is made of foam while the top layer and bottom layer can be made from a variety of films. The top layer and the bottom layer are formed in a quilted pattern. The top layer and the bottom layer are bunched up (meaning there is extra material there allowing more stretch). A method of manufacturing the waterproof composite material includes placing the three layers on (or in), stretching the middle layer, and then applying a quilt (or other) pattern (using heat and/or pressure) which causes the quilted pattern on the top layer and the bottom layer. The natural contraction of the middle layer (which was stretched when the composite was formed) causes bunching of the top layer and the bottom layer.

An orthotic device for embracing and supporting a body part (e.g., articulation) of a human or animal. The orthotic device is a single sheet of moldable Polylactic Acid (PLA) material configured to maintain the body part in an optimal position for development and treatment. An orthotic system includes the PLA sheet and a protective layer in the form of a single moldable sheet of polyethylene foam (PEF). The PEF sheet is configured for placement between the PLA sheet and the body part.

A method and device are shown for use in casting for Total Contact Casting for offloading pressure in neuropathic and diabetic wounds or fractures of the appendages such as the human leg or foot. The outer casting material used can be comprised of traditional casting materials. A total foot protection pad underlies the traditional casting materials. It is a one piece moldable system that encompasses the total foot from the Achilles along the lateral and medial foot, covering the plantar surface, the malleoli and folds and extends over the dorsum. The one piece system has adhesive backing on a contact side to facilitate its application and/or forms a total foot protection pad beneath the outer hardened casting material.

An orthopedic intramedullary sleeve apparatus for internal bone fixation for bone fracture treatment of a patient. The apparatus may comprise a multilayer sleeve component comprising one or more access valves disposed on a surface of the sleeve. Each access valve may comprise one or more resealable ports for injecting polymers or monomers or resins or any curable types of cement. The sleeve component may be positioned inside the intramedullary cavity in a minimally invasive way and removed from the intramedullary cavity.

A photocurable device injection system for creating in situ polymerization via light or free-radical to enable fractured bone fixation. The system comprises a photosensitive polymeric resin sensitive to light, temperature, oxygen, enzymes, or a combination thereof. The photosensitive polymeric resin may be configured to cure at room temperature or physiological temperature with a light source. The photosensitive polymeric resin may be configured to depolymerize with ultrasonication, sonication, or a combination thereof. The system further comprises an implantable 3-dimensional biocompatible pouch comprising an optical light guide. The system further comprises one or more micro-sized ultrasonication probes configured to contact a three-dimensional pouch by one or more openings. The one or more probes may be configured to enable polymer outflow.
