ArthroCare Announces Expanded FDA Clearance for Nucleoplasty Surgical Devices

Indication Includes Patients With Contained Herniated Discs

SUNNYVALE, CA —(BW HealthWire)— June 4, 2001— ArthroCare Corporation (Nasdaq: ARTC) today announced that the U.S. Food and Drug Administration (FDA) has granted the company clearance to market its Perc-Däfamily of disposable surgical devices specifically for disc decompression to treat symptomatic patients with contained herniated discs. Previously, the Perc-D devices had been marketed under an FDA clearance for general spinal surgery procedures.

The FDA clearance is for Coblation® assisted disc decompression procedures, a unique, minimally-invasive procedure the company calls Nucleoplastyâ. The Nucleoplasty procedure is performed with the company's Perc-D family of surgical devices, ArthroCare's patented Coblation Channeling(TM) products for the spine. As the Perc-D device is percutaneously channeled into the disc, tissue is ablated through Coblation technology's low-temperature molecular dissociation process. Thermal energy is applied while withdrawing the device to coagulate the area around the channel. Combined, these two therapies result in disc decompression and provide treatment of symptoms associated with contained herniated discs.

"I have been using ArthroCare's Perc-D surgical device in my practice to treat patients with contained herniated discs,'' said Yung Chen M.D., assistant professor of functional restoration who directs the Stanford Interventional Spine Center. "I am extremely pleased with the resolution of symptoms with a minimal post-operative regime that my patients experience with the Nucleoplasty procedure. Nucleoplasty is a very promising procedure for patients with contained herniated discs.''

"The Nucleaoplasty procedure offers physicians and their patients a minimally-invasive, out-patient option to treat symptoms of contained herniated discs,'' said Mike Baker, ArthroCare's president and CEO. "FDA clearance to market this specific procedure allows us to aggressively promote Nucleoplasty to physicians, who are already familiar with the concept of decompressing herniated discs to treat symptomatic patients.''

ArthroCare said that over 1000 Nucleoplasty procedures have been performed to date. The company is conducting Nucleoplasty training sessions throughout the world and has trained more than 300 physicians to date.
