Arteriocyte Medical Systems Forms Strategic Partnership with Medtronic including Acquisition of the Magellan Platelet Rich Plasma Business

Cleveland, OH, November 8, 2007

Arteriocyte Medical Systems announced today that the company has struck a Strategic Partnership with Medtronic that includes the acquisition of the Magellan Platelet Business, a worldwide exclusive distribution agreement in the Cardiac Surgery
Market for the next five years, and a manufacturing services agreement for the Magellan products. Medtronic’s Cardiac Surgery sales force includes 80 representatives spread throughout North America and Europe and has placed the Magellan system in over 400 surgical centers.

The Magellan System, a one-source biologic concentrator and delivery system, collects and concentrates platelets and white blood cells from a small volume of a patient’s own blood, providing a readily accessible supply of plasma that serves as a foundation for autologous platelet gel. The Magellan System presents a significant opportunity to accelerate wound healing and reduce infection in cardiac surgery, plastic and reconstructive surgery, orthopedics and vascular surgery.

“The acquisition positions our company to capitalize on the convergence of medical device and biologic delivery for patients, further differentiating our cellular therapy strategy” said Don Brown, Chief Executive Officer for Arteriocyte Medical Systems. “The Magellan System is the best platelet separation technology available, and Medtronic has developed the Magellan brand into a leader in Cardiac Surgery. We are excited to continue the development and rapid growth of the Magellan brand including expansion into markets beyond Cardiac Surgery.”

Scott Ward, President of Medtronic’s CardioVascular business added “We are pleased to partner with Arteriocyte Medical Systems. We believe the Magellan technology has the potential to benefit thousands of patients.”

Financing for the transaction was provided by DW Healthcare Partners, and Comerica Bank’s Technology and Life Sciences Division.

Roberts Mitani, LLC acted as investment banker for Arteriocyte Medical Systems.
