  • Patent number: 7429346
    Abstract: An orthopedic implant device and method is disclosed. Specifically, a knee mold system is disclosed, including elastic tibial and femoral molds, each of which may be configured and dimensioned as a unitary mold for in situ placement during a surgical procedure. Each mold may be manufactured from an elastic material that may be disposable. The tibial mold may further comprise a sidewall forming a cavity, markings for relative depth measurement, and depth rings for use as a guide for scoring, cutting, and/or trimming and tearing away an excess portion of the tibial mold. The femoral mold may further comprise a sidewall defining a cavity, two legs extending from a body of the femoral mold for forming the artificial condyles, and an eyelet for aiding in placement and removal of the femoral mold. The resulting prosthetic tibial and femoral components may form an articulation surface that mimics, at least in part, the natural articulation surface of the knee.

  • Patent number: 6540651
    Abstract: An exercise apparatus for exercising a body part is disclosed as including an attachment structure and a resistance member. The attachment structure is adapted for placement on the body part that is to be exercised. The attachment structure includes a plurality of fasteners positioned at different locations on the attachment structure. The resistance member provides resistance for exercising the body part. The resistance member has a first end and a second end. A resistance member fastener is located proximate the first end of the resistance member and is capable of fastening to at least one of the fasteners located on the attachment structure. The resistance member includes an anchor for removably attaching the second end of the resistance member to an anchor point. An apparatus for exercising a body part may also include a plurality of distinct identifications on the attachment structure for the plurality of fasteners.

  • Patent number: 6379388
    Abstract: A tibial prosthesis locking system. The system includes a tibial plate and an articular surface component or tibial insert. A proximal side of the tibial plate includes perimeter sidewalls with holding flanges formed thereon, and male retaining projections are formed on interior portions of the proximal tibial plate. A distal side of the articular surface component is designed to interlock with the holding flanges and retaining projections formed on the tibial plate. The male retaining projections and the holding flanges cooperatively engage with the articular surface component to provide it with resistance to movement in an anterior-posterior direction, a medial lateral direction, a rotational direction, and a vertical direction.
