摘要: A kit and a method for making a porous cement which self sets to hydroxyapatite and has an interconnected porosity is produced by mixing a calcium source and a phosphate source with a carbonate source and mixing this powdered component with a liquid component having an acid component. The liquid component comprises water or an aqueous solution containing an acid. The acid and the carbonate react to form carbon dioxide thereby producing an interconnected porosity in the normally solid self-hardening bone cement. The method requires only a relatively low weight percent of the acid and base to be mixed with the liquid and powder cement components.

摘要: An apparatus and method for mixing a liquid component and a powdered component to form a bone filler has first and second syringes each having a barrel, a plunger and an exit port. The plunger is moveable with the barrel of each syringe along a longitudinal axis of the barrel. An end portion of each plunger extends beyond the end of each barrel when the plunger tip is spaced from the exit port and can be activated to move the plunger tip toward the exit port. A mechanism for mixing the liquid and powdered components is operatively connected to each of the barrels and plungers of the first and second syringes so that the relative sliding movement of first and second parts of the mechanism simultaneously moves the plungers and barrels of the first and second syringes relative to one another to move the combined liquid and powdered components back and forth between the first and second syringe.

摘要: An apparatus for mixing dry and liquid components is used to form a setting paste. A holder is mounted on the apparatus for reciprocating movement with respect to a base of the apparatus. The movement has an amplitude with components in first and second perpendicular directions. A drive system is operatively connected to the holder for imparting said reciprocating movement to said holder at a predetermined number of cycles per minute. A container having a mass of said dry and liquid components therein is mounted in the holder. The mass, amplitude and cycles per minute of reciprocation being chosen to produce an energy input of at least about 3×10−3 Joules per second per 3 cc of mixture.

摘要: A process for applying a coating having a therapeutic agent such as an antibiotic or a bone morphogenic protein such as OP-1 protein to an implant uses the high surface area of a calcium phosphate coated metal implant as a repository for the therapeutic agent. The implant is coated with one or more layers of calcium phosphate minerals such as hydroxyapatite. After the crystalline layer is applied, which is usually done within an aqueous solution, the implant is dried and packaged. Immediately prior to implantation, the implant is removed from the package and the crystalline layer of calcium phosphate is wetted with an aqueous solution containing the therapeutic agent.

摘要: A spinal implant for replacing the natural nucleus of the disc made from a polymer such as hydrogel having a radiopaque material located within the polymer. The material may be in the form of a powder dispersed throughout the polymer or may be in he form of a powder dispersed in layers or in other specific locations within the polymer. The radiopaque material is metal such as gold, tungsten, titanium, tantalum or platinum. The metal may also be in the form of a foil or wire located within the hydrogel such as polyurethane, thereby making the implant visible on x-rays. Other polymers besides hydrogel may be used with the radiopaque material being dispersed therein.
