The less-invasive version features a reduced L5 crossbar configurationthat the company feels will further reduce tissue retraction and operativetime during TOPS(TM) implantation.

"The procedure went very well," commented Dr. Coric. "I feel this newversion is a significant improvement over the original TOPS(TM) design and isa natural progression of making implants as minimally-invasive as possiblewhile still being able to withstand the biomechanical demands of the lumbarspine."

Andrew Shepherd, Vice President of Sales and Marketing for Impliant, said,"We are pleased to add this less-invasive option to our TOPS(TM) family ofproducts. This line extension is a result of input we received from ourTOPS(TM) investigators to help further improve the ease of insertion of thedevice."

Impliant recently received FDA approval to begin re-enrolling patients inits prospective, randomized IDE study comparing the TOPS(TM) System to atraditional posterior fusion. The company voluntarily suspended enrollment inthe study in September of last year following one device-related failure.

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.
