Tissue Block for Suture Practice
Traditionally, medical students have practiced suturing on tissue mimics made from silicone or polyurethane elastomers. These materials lack the lubriscious nature of natural tissue. Using our proprietary hydrogel technology, CPG has developed single and multi-layer tissue blocks that contain a similar amount of water as natural tissue, and hence provides a similar feel as natural […]

FDA Clears Ecima
The FDA has cleared ECiMA(tm), a highly crosslinked polyethylene containing Vitamin E, for use in hip arthroplasties. ECiMA is sold by Corin, and was developed by researchers at Cambridge Polymer Group and the Massachusetts General Hospital. ECiMA was developed as a second generation highly crosslinked UHMWPE to replicate the good wear properties of the first […]
Hip Implant Recall
Johnson & Johnson has continued to investigate their metal-on-metal implants, which were recalled in 2010 due to some patients reactions to metal debris generated during articulation. In a Reuter’s report today, J&J had fourth quarter charges of $800 million associated with medical costs related to the recall.
Radiopacity in Medical Devices
Temporary or permanent implants often contain a radiopacifier, which is a material with a higher electron density contrast compared to the surrounding material so that it absorbs X-ray energy. In an X-ray, a radiopacifier appears as a bright section, as shown in the catheter above (the internal wire is a radiopacifier). Radiopacifiers are often made […]
Hydrogel Skin Model
Synthetic tissue constructs have been around since the 1970’s, when Dr.’s Yannas and Burke created an artificial skin from collagen and silicone rubber. This membrane, termed Silastic, was designed to mimic the properties of skin, to help generate new skin in burn victims. Researchers from the Medical School Hannover (Germany) are trying to replicate human […]
Highly Crosslinked UHMWPE Available for License
Cambridge Polymer Group and Massachusetts General Hospital have co-developed novel, highly crosslinked ultra high molecular weight polyethylenes that incorporate vitamin E and are suitable for hip, knee, shoulder and spine arthroplasty applications. These technologies, generically termed CIMA, E-CIMA and Reservoir Vitamin E, are available for license. E-CIMA E-CIMA is a formulation containing Vitamin E throughout […]
Annual Meeting of the Orthopedic Research Society
CPG will have an exhibit at the upcoming annual meeting of the Orthopedic Research Society in San Francisco, CA, from February 4th to February 7th. This conference brings researchers, medical device manufacturers, surgeons, and regulatory agency representatives together to discuss the latest technologies, practices, and clinical outcomes in the area of orthopedic surgery, including hip, […]
Synthetic Tissue Models
Cambridge Polymer Group is now partnered with Pulse Anatomy to produce custom anatomy models made from our patented materials for use in clinical device development and professional education. Pulse replicates the anatomy using digital data as a starting point for the process of printing of rapid prototyped parts, creating molds and producing castings. Pulse’s team […]

Increased Data Collection in Medical Devices
The U.S. Senate has introduced a bill that allows the FDA to require medical device companies to collect and track data on the clinical performance of their marketed devices, such as hip and knee replacements. This action is in part due to the on-going reported issues of metal-on-metal hip implants failing due to metal ion […]
Product Differentiation
When marketing a new product, differentiating your product from your competition can be a nuanced activity, depending on the nature of the product. In more tightly regulated markets, customers may require side-by-side comparisons of their existing approved and validated products with your new offering, to ensure that it has the same or better properties. As […]
