CPG has developed a new highly crosslinked UHMWPE stabilized against oxidation with the Massachusetts General Hospital. The material is suitable for total hip and knee arthroplasty bearing surfaces. The material has excellent wear behavior and good mechanical properties. Please contact email@example.com for more information.
Cambridge Polymer Group received a U.S. patent allowance for its injectable hydrogel formulations for biomedical applications. The patent addresses methods for preparing a biocompatible liquid that gels in vivo without chemical reaction. CPG is developing this technology for nucleus pulposus augmentation, orthopedic applications, synthetic tissue models, and tissue bulking.
CPG researchers Gavin Braithwaite and Jason Berlin were awarded a SBIR grant from the NIH to develop an injectable hydrogel formulation to aid in urinary incontinence. This research will use CPG's proprietary hydrogel formulation, which cures without chemical reaction.
Cambridge Polymer Group has won a grant from the NIH (NIAMS 1R43AR056892-01A1) to continue development of their injectable hydrogel for nucleus pulposus replacement in the intervertebral disc. This funding will be used to finalize the formulation and to conduct long term fatigue studies on their patented technology.
CPG researchers Bayen Miller and Gavin Braithwaite received a Small Business Innovation Research grant from NIST to develop a micro-shear rheometer for solutions and melts. This work will be conducted in CPG's Prototype Division.
ThermoFisher Scientific, who licensed the CaBER extensional rheometer from CPG, has announced that it is now offering a normal force option on the CaBER, which will permit force measurements during extension, as well as stress decay after extension has stopped. The normal force transducer has a resolution in the mN range.
Gavin Braithwaite and Jason Berlin will be presenting their work on "Surgically relevant in vitro testing of injectable PVA nucleus replacement hydrogels at the Spine Arthroplasty Symposium (SAS9) in London, England on April 28-May 1, 2009.
CPG is pleased to announce the hiring of Martin Van Buren, who joins CPG as a senior research scientist. Marty has extensive experience in polymer synthesis, having worked several years in the contact lens arena, as well as polymer membranes for battery systems.
CPG researcher Stephen Spiegelberg participated in webcast panel discussion of highly crosslinked ultra high molecular weight polyethylenes for the orthopedic industry. The event was sponsored by Biomet. The presentations and discussion can be seen by following the link below.
The United States Patent Office issued patent #7507774 to Cambridge Polymer Group, for "A high modulus crosslinked polyethylene with reduced residual free radical concentration prepared below the melt."
CPG researchers Jason Berlin and Gavin Braithwaite presented their work on a novel injectable hydrogel formulation for nucleus pulposus replacement at the 2009 Orthopedic Research Society meeting in Las Vegas, NV.
