Sono-Tek Corporation Announces the MediCoat PSI, Peripheral Stent Coating System

MILTON, N.Y., May 29, 2007 /PRNewswire-FirstCall via COMTEX/ -- Sono-Tek Corporation (OTC Bulletin Board: SOTK), announced today the release of the MediCoat PSI. The MediCoat PSI offers the same cutting-edge precision stent coating features as the well established MediCoat DES systems used for coating cardiac stents. The new PSI model is ideal for coating large peripheral stents, and it is capable of coating, in one cycle, multiple stents up to a cumulative length of 8 inches.
MediCoat PSI incorporates Sono-Tek's proven MicroMist ultrasonic atomizing nozzle, and provides stent motion that assures complete coverage of large vascular stents.

Sono-Tek CEO and President, Dr. Christopher L. Coccio stated, "The MediCoat PSI, is a logical addition to the family of Sono-Tek stent coating systems. The application of applying drug/polymer coatings onto peripheral stents is in its infancy; however, several of the large stent manufacturers are pursuing this option. Many of these companies already use MediCoat DES systems from Sono-Tek to coat their cardiac stents. Providing them with solutions for use with peripheral stents is ideal for us. Our first system was recently sold and well received by the customer."
