Transforming medical devices for improved patient outcomes

Micell Technologies’ MiStent SES® Now Commercially Available in Europe

— Novel Drug-delivery Technology Provides Sirolimus-Eluting Stent with Unique Bioabsorbable Polymer Absorption and Drug Release Profile —

DURHAM, N.C. – Feb. 4, 2015 – Micell Technologies, Inc., a biomedical company that is enhancing the performance of cardiovascular medical devices with innovative drug-delivery systems, today announced the commercial availability of the MiStent® Sirolimus Eluting Absorbable Polymer Coronary Stent System (MiStent SES®) in Europe. STENTYS, Micell’s distribution partner in Paris, plans a controlled launch in Western Europe followed by a full commercial launch for the second half of 2015 in selected countries within Europe, Middle East, South-East Asia and Latin America.

Arthur J. Benvenuto, chairman and chief executive officer of Micell said, “Patients with cardiovascular disease and their physicians now have access to a new class of drug-eluting stent that allows the drug to remain in the tissue for an extended period — well beyond a rapidly- absorbing polymer. This performance feature is unique to MiStent and until now, has been largely impossible. Most importantly, it has translated into meaningful clinical benefits.”

MiStent SES has received CE Mark in the European Union, and will be distributed exclusively by STENTYS around the world, with the exception of the United States, Canada, China, South Korea and Japan. Micell is in the process of expanding its manufacturing capabilities through its partner, Surgical Technologies, Inc., based in St. Paul, Minn.

“We are very excited to be partnering with Micell on the distribution of MiStent,” said Gonzague Issenmann, chief executive officer for STENTYS. “We believe MiStent is a great addition to our stent portfolio, and we look forward to launching this innovative product.”

About the MiStent SES

MiStent SES® is designed to optimize healing in patients with coronary artery disease. The rapidly absorbable coating of the MiStent SES is intended to precisely and consistently provide for local drug delivery and limit the duration of polymer exposure, thereby potentially reducing the safety risks associated with current commercially available drug-eluting stents. The MiStent SES includes a proprietary stent coating that contains crystalline drug (sirolimus) and an absorbable polymer. The coating provides controlled and sustained release of therapeutic levels of drug as the polymer disperses from the stent into the adjacent tissue. These properties are intended to enhance safety as compared to conventional permanent polymer drug-eluting stents.

Results of animal studies have determined that the coating is cleared from the stent in 45 to 60 days leaving a bare-metal stent, and the polymer is completely absorbed into the surrounding tissue within 90 days to promote long-term patency and compatibility with the artery. The crystalline drug remains in the tissue and continues to elute sirolimus for up to 9 months.

Using an approved drug (sirolimus) and polymer (PLGA), Micell’s patented supercritical fluid technology allows a rigorously controlled drug/polymer coating to be applied to a bare-metal stent. The MiStent SES leverages the benefits of a cobalt chromium coronary stent system, a state-of-the-art, thin-strut, bare-metal stent, which has demonstrated excellent deliverability, conformability and flexibility.

EU approval of MiStent SES was supported by clinical data from two studies, DESSOLVE I and II, which demonstrated superior in-stent late lumen loss rates and an excellent safety profile. The three-year follow-up of the DESSOLVE clinical studies subjects was completed in 2014, and these patients continue to undergo long-term follow up.


STENTYS is developing and commercializing innovative solutions for the treatment of patients with complex coronary artery disease. STENTYS’ Self-Apposing® Stents are designed to adapt to vessels with ambiguous or fluctuating diameters in order to prevent the malapposition problems associated with conventional stents. STENTYS has built a fast-growing commercial network in Europe and in many countries in the Middle East, Asia and Latin America. More information is available at
