Impliant had voluntarily suspended all clinical activities in September oflast year following one device-related failure. After an extensiveinvestigation conducted by a third-party expert inmedical device retrievals and the Impliant Research and Development team, itwas determined that device misalignment coupled with excessive shear loadingcaused the failure. As a result, Impliant has made a few minor design andmanufacturing changes to the internal components of the TOPS(TM) device thatallow it to better withstand high shear loads and misalignment while notaffecting its range of motion.

"I am pleased with the changes Impliant has made to the TOPS(TM) System,"said Mr. Sutcliffe. "I feel the device is now even better suited to stabilizethe spinal segment after performing the wide decompression that my severelystenotic patients require. However, it should be noted that all of my patientswith the original TOPS(TM) design continue to do extremely well, some of whichhave reached 12 months post-op."

Marcus Klarl, Vice President of European Clinical Affairs for Impliant,stated, "We are pleased to resume our TOPS(TM) clinical activities outside theUnited States and build upon the excellent outcomes generated to date by Mr.Sutcliffe and our other TOPS(TM) investigators."

The TOPS(TM) single and multi-level family of products have been implantedin over 80 patients in Brazil, South Africa, Belgium, Turkey, Israel, Germanyand the United Kingdom. The company also recently received FDA approval torestart its TOPS(TM) IDE clinical study in the United States.

Impliant is applying cutting-edge materials and crossbar biomechanicaltechniques to develop a new class of spine arthroplasty devices that targetover 40% of the patients worldwide who undergo fusion surgery and couldbenefit from a Total Posterior Arthroplasty solution.
