During cooling the thermoplastic elastomer may be molded or otherwise formed into any number of articles including, but not limited to, prosthetic liners, prosthetic sleeves, external breast prostheses, breast enhancement bladders, wound dressing sheets, wound dressing pads, socks, gloves, malleolus pads, metatarsal pads, shoe insoles, urinary catheters, vascular catheters and balloons for medical catheters both vascular as well as urinary.

An implant for causing fusion of bones in an ankle is disclosed. The implant, in a preferred embodiment, is a cannulated screw with threads at the leading end and threads at the trailing end having a a tibial component that interacts with the tibia, a calcaneus component that interacts with the calcaneus and a midsection extending between the tibial component and the calcaneus component. The implant is placed in a borehole formed in the tibia, talus and calcaneus and causes the tibia and talus to be moved into compressive contact with each other. As a result, the ends of the tibia and talus that have previously had the cartilage removed down to bloody bone are coapted together to allow fusion. In another embodiment of the invention, a middle threaded portion is placed between the tibial component and the calcaneus component. The middle threaded portion interacts with the talus to help add compressive force to the fusion process. The invention also includes a method for using the implant to fuse the bones of the ankle together. The method includes steps of producing an implant and then using the implant to apply compressive forces on the bones of the ankle. The invention in one embodiment also includes a method that uses images such as x-ray images preoperatively to determine the length and width of the disclosed implant or any other implant with each patient's unique anatomy will properly allow coaption of the ends of the prepared tibia and talus at the ankle joint. The implant is inserted from the bottom of the foot through a predetermined hole in the calcaneus which extends through the talus into the diaphysis of the tibia. When properly inserted and seated in the bones, the implant is locked by screws.

Each of the functional shoes an ankle contact member mounted to the heel counter of the shoe, which supports the rear portion of a foot, which ranges from the heel of a foot to an ankle, formed in a shape that corresponds to the concave shape of the rear portion of the ankle, and coming into contact with an ankle stimulation portion; an ankle stimulating member mounted from the inside of a shoe outsole to the ankle contact member, and transmitting physical stimulation to the ankle stimulation portion, which is the concave rear portion of the ankle malleolus, using force that is applied by the foot while walking; a heel stimulating member mounted in the shoe outsole, which corresponds to the central portion of the rear portion of a sole, formed to have hardness higher than the outsole, and transmitting load stimulation, caused by applied force, to a heel stimulation portion, which corresponds to the central portion of the rear portion of the sole; and an electrical stimulation unit, comprising a power generation device which is mounted in the shoe outsole and generates power, and power generation points which are formed on an ankle stimulation part and/or the heel stimulation portion.

An ankle foot brace having a heel stirrup, a lower lateral and medial uprights, and an upper lateral and medial uprights hinged to the respective lower uprights. A malleolar window, preferably with a membrane extending thereupon, creates a hammock like support for the malleolus. The hinge point on the side having the malleolar window is moved upwards and preferably back from the apex of the malleolus. Doing so allows the application of tolerable corrective forces at this location to help prevent undesired movement of the malleolus. If a membrane is not employed, the window allows application of corrective forces in the vicinity of the malleolus without causing pain thereto.

An ankle foot orthosis that may be used for children with lower extremity spasticity or muscle weakness to prevent deformity and enhance extremity function. The orthosis includes an adjustable tension assembly connected to an upper leg portion and a lower foot portion. The tension assembly includes a tension adjuster connected with an elastomer band, with the tension adjuster being operable to selectively increase or decrease the amount of stretch applied to the elastomer band to provide a selectable upward biasing force to a patient's foot. The dynamic orthosis creates a variable load stretch below the knee preventing muscle contracture, heel cord shortening, and increases range of motion and is utilized during rest, sleep, and short distant weight bearing providing readings of the range of motion continuously. The orthosis incorporates a circumferential dynamic support system that maintains corrected alignment of the bones of the foot and ankle.
