Title: Innovations by Bryan M Barr
Introduction
Bryan M Barr is a notable inventor based in San Jose, California, with a remarkable portfolio of 17 patents. His work primarily focuses on advancements in calcium phosphate cements, which have significant applications in the medical field.
Latest Patents
Among his latest patents, Bryan has developed storage stable calcium phosphate cements. These two-component, storage stable apatitic cement compositions are designed for efficient production methods. The dry component of these apatitic cements consists of basic calcium source particles that are at least partially coated with a partially neutralized acidic calcium phosphate. The preparation involves combining basic calcium source particles with dissolved acidic phosphate in a partially aqueous medium, allowing for the coating of the particles. The reaction is carefully controlled by removing available water before completion. In one method, the cement is produced by mechanically mixing an acidic phosphate source with basic calcium source particles in the presence of an aqueous solvent, halting the reaction before it fully completes. Alternatively, a phosphoric acid solution can be rapidly combined with a basic calcium phosphate particle slurry, resulting in the precipitation of partially neutralized acidic calcium phosphate on the surface of the basic calcium phosphate particles.
Additionally, Bryan has developed kits for preparing calcium phosphate minerals, which enhance the setting times of calcium phosphate cement compositions through the addition of phosphate or carbonate lubricant compositions.
