Boston Scientific Announces Acquisition of Precision Vascular Systems, Inc.
(April 7, 2004) -- Boston Scientific Corporation (NYSE: BSX) today announced that it has acquired Precision Vascular Systems, Inc. (Precision Vascular), a privately held company located in West Valley City, Utah. Boston Scientific exercised an exclusive option to acquire Precision Vascular that it obtained as part of a series of agreements between Boston Scientific and Precision Vascular in 2002. Terms of the acquisition were not disclosed.

Precision Vascular designs, develops and manufactures high performance medical devices for use in accessing the brain, the heart and other areas of the anatomy. Its primary focus has been the development of a proprietary line of guidewires and microcatheters using a microfabrication manufacturing process that cuts minute slices in small-diameter nitinol tubes. These tubes are designed to improve performance characteristics of guidewires and catheters, making it easier for physicians to access complex parts of the anatomy. Precision Vascular was founded with intellectual property and technology originally developed by Sarcos, Inc. Sarcos, Inc. is a research and development company specializing in medical devices, microsystems and robotics.

Precision Vascular's current portfolio of approved devices is used primarily for accessing brain aneurysms, tumors and other blood vessel lesions of the brain. Boston Scientific has identified potential applications of the Precision Vascular technology to projects in its interventional cardiology, oncology and endoscopy businesses, including a new interventional cardiology guidewire platform currently under development.

The total worldwide market for vascular access devices, including interventional guidewires and microcatheters, is estimated to be greater than $500 million annually. Demand for high performance access devices is expected to continue to grow with the increasing complexity and number of endovascular and endoscopic procedures being performed.

"We are pleased to welcome the Precision Vascular team to the Boston Scientific family," said Paul LaViolette, Boston Scientific Senior Vice President and Group President, Cardiovascular. "Their 10 years of experience in microfabrication development and manufacturing will prove valuable as we explore future high performance Boston Scientific catheter products to help clinicians access complex target sites."

"The acquisition of Precision Vascular by Boston Scientific represents the culmination of a strong working relationship developed by the companies during the 18 months since we established our distribution agreement and began collaborating on product development," said Ken Osborn, President of Precision Vascular. "I am looking forward to continuing our work together as part of the same company."
