The Nation's Leading Plastic Surgeons Learn about ArteFill's Five Year Safety and Long-Term Efficacy Data

SAN DIEGO--(BUSINESS WIRE)--May 6, 2008 - Artes Medical, Inc. (Nasdaq:ARTE), a medical technology company whose product ArteFill is the first and only FDA-approved non-resorbable injectable dermal filler for the correction of "smile line" wrinkles, had data showcased demonstrating ArteFill's safety and long-term efficacy at the annual meeting of the American Society for Aesthetic Plastic Surgery (ASAPS). This long-lasting treatment has been increasing in popularity and is the only wrinkle filler on the U.S. market to have five-year clinical data presented.

"Artes Medical's comprehensive long-term study appears to confirm the safety profile of ArteFill in patients five years after treatment and demonstrates that ArteFill continues to provide optimal wrinkle correction over time," said Steven R. Cohen, M.D., Private Practice, San Diego, CA and Clinical Professor, Division of Plastic Surgery, University of California, San Diego School of Medicine.

In addition to presentations on ArteFill's safety, long-term efficacy, and differences among various dermal filler products, leading plastic surgeons had the opportunity to observe ArteFill in action. Dr. Cohen provided a live patient demonstration with ArteFill injections during "The Importance of Non-Surgical Options in Your Practice" session, showcasing ArteFill's ease of injection, immediate correction and minimal downtime.

"Our physicians are pleased to be able to offer their appointment-weary patients a long-lasting solution for their smile lines," said Diane S. Goostree, president and chief executive officer, Artes Medical. "This key industry medical meeting gives physicians the latest information about ArteFill's demonstrated wrinkle correction five years following treatment."

About ArteFill(R)

ArteFill is the first and only FDA-approved non-resorbable injectable dermal filler for the correction of wrinkles known as smile lines or nasolabial folds. The unique microspheres in ArteFill are not absorbed by the body and therefore provide the first-of-its-kind permanent support for long-lasting wrinkle correction in one to two treatments.

ArteFill was approved by the FDA in October 2006 based on data from the Company's 12-month controlled, randomized, double-masked, multi-center U.S. clinical trial, which compared outcomes for patients treated with ArteFill with those of patients treated with the leading bovine collagen-based filler. At the 6-month evaluation, which was the primary efficacy evaluation period for the clinical trial, the wrinkle correction in patients treated with ArteFill persisted and showed statistically significant improvement compared to the wrinkle correction in the patients treated with the collagen control, who returned to their pretreatment status. The ArteFill patients were also evaluated one year after treatment, demonstrating continued safety and wrinkle correction.

In December 2007, the Company announced that ArteFill's 5-year safety and efficacy data was published in the peer-reviewed journal Dermatologic Surgery "Filler Issue." This publication addresses the robust, long-term, efficacy and safety profile of ArteFill. This 5-year follow-up study included 145 patients who were treated with ArteFill in the Company's U.S. clinical trial. In addition to demonstrating the safety profile of ArteFill, the study showed statistically significant (p less than 0.001) improvement in patient wrinkle correction five years after the patient's last ArteFill treatment, and a statistically significant (p=0.002) improvement in wrinkle correction at the 5-year point compared to the 6-month evaluation period. As part of the study, physician investigators and patients were asked to provide their assessment of ArteFill treatment. Over 90% of the physician assessments were either "completely successful" or "very successful"; and over 90% of the patient assessments were either "very satisfied" or "satisfied". In March 2007, the Company submitted the data from the study to the FDA for review in order to enhance the product labeling for ArteFill.

An ArteFill Skin Test is required before initial treatment. The most common adverse events associated with ArteFill treatment, similar to those observed with other dermal fillers, are lumpiness, persistent swelling or redness and increased sensitivity at the injection site.

ArteFill is a proprietary formulation comprised of polymethylmethacrylate, or PMMA, microspheres and bovine collagen, and is the only PMMA-based injectable product that has been approved by the FDA for the treatment of facial wrinkles. Artes Medical is the sole manufacturer of ArteFill, which is only available in the United States through Artes Medical, and Artes Medical has not entered into distribution or licensing arrangements with any third party for the distribution or sale of ArteFill, or any other PMMA-based dermal filler, outside the United States.
