  • Integrated keel-pylon prosthesis
    Patent number: 5993487
    Abstract: A prosthetic component is described for use in a human lower limb prosthesis. The component can consist of an integrated pylon-keel or foot component. The preferred methods of manufacture are thermoforming or injection molding. The use of a single piece of plastic allows for improved energy storing and release characteristics while heightening the wearer's sense of weight reduction.

  • Continuous one-piece prosthesis
    Patent number: 5336270
    Abstract: A one-piece continuous polymeric prosthesis is disclosed and taught. The prosthesis is intended for patients with a below-knee amputation. The one-piece socket-pylon-keel allows good energy storage and release for a superior feel during physical activities. The construction and the materials makes for a much lighter weight prosthesis than conventional types.
