Description:
Project ID: D2011-33
IP Status: Patent Pending U.S and Europe
Invention Description: Novel method to prepare an implantable article comprised of a biocompatible substrate (polymeric or ceramic) to accept a very thin biocompatible, bioactive coating material to facilitate bio-ingrowth between the substrate and bone or cartilage tissue.
Applications: Bone fractures treated with wires, nails, screws, and plates; joints replaced by artificial endoprostheses; dental implants; other.
Novelty: Uses microwave energy to form a carbonated calcium deficient hydroxyapatite (CDHA) layer on the surface of implants to solve problems inherent to materials for implants produced from metals, polymers, ceramics and calcium phosphates (CaP).
Value Proposition:
• BIOACTIVE + BIOCOMPATIBLE: Technology produces a biocompatible and bioactive form of calcium phosphate coating which will degrade and facilitate bone formation for faster patient healing and recovery.
• VERSATILE: Efficiently coats polymers and other substrates.
• FASTER PROCESSING TIME: Commercially efficient processing time. Newly developed technology performs the coating process within minutes to a few hours thus allowing for converting the batch process to a continuous process.
• THIN: Coating is very thin so as not to introduce fatigue under tensile loading or create residual stress, releasing energy which may promote interfacial debonding or flaking.
• Forms direct bonds to newly formed bone tissue in the body;
• Features biochemical and biomechanical properties suitable for load bearing orthopedic implants;
• No degradation in-vivo;
• Limited animal data is available.
