Lower limb orthotic brace

United States Patent # 6,146,344 .pdf

A lower limb orthotic brace to control the movement of the lower limb of a patient comprising a contoured orthotic contact shell and an integral load-bearing frame, the contoured orthotic contact shell comprises at least one layer of fabric impregnated with a hardened structural resin forming an inner orthotic contact surface conforming to the outer surface of the lower limb of the patient and the integral load-bearing frame comprises at least one reinforcing member extending along the contoured orthotic contact shell including a plurality of bundled continuous composite fibers woven in a multidirectional tubular braid impregnated with a hardened structural resin with at least one side of the braid in contact with the contoured orthotic contact shell along the entire length of the braid such that the hardened resins impregnating the fabric of the contoured orthotic contact shell combine with the resins impregnating the braid thereby forming a continuous integral structural matrix encapsulating both the braid and the contoured orthotic contact shell.

Rigid lower-limb orthotic

United States Patent # 5,817,041 .pdf

A lower limb orthotic comprising a foot orthotic, a pair of lateral supporting members, a detached or removeable anterior support member, a posterior support member, and strips of composite materials to resist plantar flexion, dorsiflexion and various of movements of the foot and ankle. The lateral supporting members further having strips of composite materials having fibers orientation substantially parallel to the length wise axis of the lateral supporting members. The foot orthotic and posterior supporting member further have composite strips extending across the bottom portion of the foot orthotic and rear side of the posterior supporting member respectively.

Method of Producing an Orthotic Brace or Prosthetic Device

United States Patent # 7,749,423 .pdf

A method of producing an orthotic brace or prosthetic device comprising the steps of creating an anatomical mold or cast of that portion of the patient's anatomy upon which the orthotic brace or prosthetic device is to be applied, applying at least one layer of epoxy resin over at least a portion of the anatomical mold, applying at least one layer of carbon graphite fabric on at least a portion of the layer of epoxy resin, placing the anatomical mold with the epoxy resin and carbon graphite fabric in an enclosure having an interior, heating the interior of the enclosure to melt the epoxy resin and reducing the pressure in the interior of the enclosure causing the melted epoxy resin to impregnate the carbon graphite fabric, and allowing the melted epoxy resin to harden in the carbon graphite fabric forming the orthotic brace or prosthetic device.
