Simbex Press Release

The Socket Renewer™ uses the patented Active Contact System™ volume management technology to renew trans-femoral socket fit.

Lebanon, NH - March 19, 2003 - Simbex LLC announced today that it is unveiling a new member of the Active Contact System™ product line at the American Academy of Orthotists and Prosthetists (AAOP) national meeting in San Diego, California on March 19, 2003.

The Socket Renewer™ was conceived to be an easy add-on to an existing transfemoral prosthesis that can improve the comfort and performance of a prosthesis for those who cannot maintain an intimate fit with their prosthesis due to natural limb volume fluctuations. This product uses Simbex's flagship Active Contact System™ technology introduced at last year's AAOP National Meeting in Orlando.

"We knew the market was waiting for the introduction of our SR - 80 Volume Manager [referring to the Active Contact System™ Socket Renewer™ 80 Volume Manager] but we had to prove the technology with the IC - 110 version [referring to the Integrated Case Model]," according to Richard M. Greenwald, President and co-founder of Simbex. The IC - 110 model is better adapted to the fabrication process of new socket construction, while the SR - 80 has no effect on build-height and can easily be mounted internal or external to the hard frame of the prosthesis.

Active Contact System was given a rigorous market test by the use of an innovative, controlled, introductory sales program called the "PDP Program" (Product Development Partner). Simbex engaged prosthetists nationwide to try the Active Contact System™ and report on the satisfaction of amputees for fit and function and prosthetists and technicians for ease of installation. "In order to meet our ambitious objectives for product development, we had to finish our clinical trials and turbo-charge the field trials to get the most results possible. We want to thank the many prosthetists that participated with us to put the technology to the test," said Greenwald.

The new product will be unveiled at the San Diego AAOP National Meeting March 19 - 22, 2003 and should be ready for delivery in early May.
