  • Motion limiting insert for an artificial intervertebral disc
    Patent number: 9034038
    Abstract: A spacer for an artificial spinal disc arrangement is provided. The artificial disc arrangement includes an upper plate, a lower plate, and articulating surfaces between the upper and lower plates arranged to permit motion between the upper and lower plates. The spacer has a first surface for contacting the upper plate and a second surface for contacting the lower plate and is of sufficient thickness such that, when disposed between the upper and lower plates, the spacer limits motion between the upper and lower plates. An artificial disc, a method of limiting motion of an artificial disc in a patient, and a method of performing spinal disc surgery are also disclosed.
    Type: Grant

  • Intimate mixture of calcium and phosphate sources as precursor to hydroxyapatite
    Patent number: 5178845
    Abstract: Novel compositions are provided for the production of hydroxyapatite, where a dry mixture is provided which combines a calcium source and an acidic phosphate source, particularly monocalcium phosphate monohydrate or orthophosphoric acid crystals. These two are combined, optionally with other ingredients, with mechanical mixing, resulting in partial reaction or intimate combination to produce a product which requires less water for formation of a desired viscosity, has enhanced mechanical properties and is physiologically acceptable.
