  • Publication number: 20130297025
    Abstract: A flexible prosthetic cover shaped to form a replacement nucleus pulposis for an intervetebral disc with an aperture for the introduction of filling material therein, and an elongate introducer member configured to pass into the aperture is provided. The cover has a strengthened portion substantially opposite the aperture for engaging the distal end of the member, the strengthened portion and the distal end being arranged to interlock, for facilitating orientation of the cover, for example so as to prevent relative rotation there between.

  • Publication number: 20130237892
    Abstract: A fracture brace for the treatment of limbs with bone fractures has a first portion comprising a rigid shell having at least two load areas for contact with the limb; a second portion comprising at least one load area for contact with the limb; and a strap adapted to encircle the first and second portions. The first portion has a resilient material attached to the radially outer part of the shell, and the strap overlies and compresses the resilient material so that the fracture brace exerts pressure on the limb, so that the resilient material re-expands upon any decrease of swelling in the limb to maintain pressure on the limb. As the fracture swelling subsides, the resilient material reacts by partially returning towards its original shape, so that any slackening of the strap caused by the reduced swelling is taken up by the resilient material.

  • Patent number: 7182742
    Abstract: An orthopaedic brace apparatus for the treatment of fractures is described. The brace comprises two portions (2,3) joined together by a strap (4). The first portion (2) comprises at least one preformed pad and the second portion (3) comprises at least two preformed pads (5, 6) joined together by resilient material (7). The resilient material is elastically deformable and the preformed pads are formed from a material that resists slippage such that the apparatus provides gentle compression on the fracture.

  • Publication number: 20050065609
    Abstract: A flexible prosthetic cover (12) shaped to form a replacement nucleus pulposis for an intervetebral disc comprises an aperture for the introduction of filling material therein, and an elongate introducer member (28) configured to pass into the aperture. The cover has a strengthened portion (26) substantially opposite the aperture for engaging the distal end (42) of the member, the strenghtened portion and the said distal end being arranged to interlock, for facilitating orientation of the cove, for example so as to prevent relative rotation there between.

  • Patent number: 6692496
    Abstract: The invention provides apparatus for the treatment of a bone fracture (18′), comprising an elongate member (2) adapted for substantially axial insertion into the bone (18) such that it spans the fracture; where in one embodiment the elongate member being formed, adjacent one or both of its proximal and distal ends with fixture location means (9) adapted to receive a fixing device (27) inserted transversely of the elongate member (2) and passing through part at least of the bone to be treated; the position of the fixture location means (9) and the line of insertion of the fixing device (27) being defined by a jig (21) temporarily affixable to the proximal end of the elongate member; wherein a guide means (25) is adapted to pass through the fixture location and act as a guide for the desired location of the fixing device, said apparatus also providing drill means (25a and 26a), guidable by the guide means, and utilizable to form a bore communicating with the fixture location and adapted to accommodate the

  • Patent number: 6402784
    Abstract: The present invention provides a prosthetic cover (12) shaped to form a replacement nucleus pulposis (56) for an intervertebral disc (50), said cover comprising a permeable layer of an immunologically neutral material terminating in a valve structure (16) to allow the introduction of a hydrogel material (14); characterized in that a transudative material is disposed on the intended inner face of the cover to allow a through flow of low molecular weight materials only.

  • Patent number: 4796611
    Abstract: An orthopaedic brace for use in the treatment of fractures of a lower part of a limb such as the wrist or ankle is described. The brace comprises of two preformed portions, a first portion has two areas of high loading arranged distally and proximally on the portion and a second portion has one area of high loading at or near its center whereby the portions when fitted around a limb and fracture provide three point loading of the limb applied in two planes thereby maintaining the position of the fracture throughout the treatment period. In a preferred form the brace is used to treat Colles' fractures whereby the first portion fits on the dorsal/radial part of the arm and the second portion fits on the anterior/ulnar part of the arm, the two portions being held in place by means of straps attached to the first portion.
