December 8, 2009 New highly crosslinked UHMWPE

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 info@campoly.com for more information.

October 7, 2009 US patent issued for injectable hydrogel

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.

September 14, 2009 CPG awarded NIH Grant for 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.

July 31, 2009 CPG awarded NIH Grant for Nucleus Pulposus Replacement

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.

June 24, 2009  CPG awarded NIST SBIR

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.

April 28, 2009 CaBER add-on components

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.

April 21, 2009  In Vitro Testing of Nucleus Pulposus Replacements

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.

April 9, 2009  New Senior Scientist

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.

March 10, 2009  Webinar on Crosslinked UHMWPE

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.

March 6, 2009 Highly Crosslinked UHMWPE Patent Issued

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."

March 5, 2009 Nucleus Pulposus Presentation at ORS

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.
