Company Strengthens Infrastructure to Support Growing Demand for Its Revolutionary Mobetron® Device

SUNNYVALE, Calif. September 7, 2006 IntraOp Medical Corporation (OTCBB: IOPM) has promoted Rick Belford to Vice President of Quality Assurance and Regulatory Affairs, and Tom Cook to Director of Customer Support. These two newly created positions strengthen IntraOp's corporate infrastructure, while adding support for the growing demand of the Company's Mobetron system, an FDA-cleared device used to deliver intraoperative electron radiation therapy (IOERT) during cancer surgery.

Mr. Belford has over 30 years of quality assurance and regulatory affairs experience within the medical technology industry. For the past eight years, Mr. Belford has served as IntraOp's Director of Quality Assurance and Regulatory Affairs. In his new capacity as Vice President of Quality Assurance and Regulatory Affairs, he will have increased responsibility for overseeing all aspects of the Company's quality programs and worldwide regulatory compliance. IntraOp Medical is certified to the ISO 13485:2003 standard for medical device manufacturing and maintains 510(k) FDA approval for the Mobetron in the U.S., CE mark in Europe, JIS in Japan, and SDA in China.

In addition, Tom Cook, who has over 30 years of radiation therapy device service and management experience, has been named Director of Customer Support. Mr. Cook has served as IntraOp's Service Manager since 1995. As Director, he will oversee the installation of new Mobetron systems, the training of technicians who operate the Mobetron in hospitals, and the growing IntraOp service business provided by IntraOp's own personnel and its distributors worldwide.

"The promotions of Mr. Belford and Mr. Cook strengthen two very critical components of our business: maintaining worldwide regulatory compliance of the Mobetron and providing superior customer service and support," said Dr. Donald A. Goer, Chairman and Chief Executive Officer of IntraOp Medical. "These promotions will add depth and flexibility to our management team while enabling us to effectively support the growing demand for the Mobetron worldwide." In related company news, IntraOp announced that Mr. Paul J. Crowe, who is also the founder, Chairman and CEO of Nuview Radiopharmaceuticals Corporation, has resigned from the Company's board of directors due to his other business commitments. "Paul has been a great asset to IntraOp," commented Dr. Goer. "He helped give the company guidance and direction during his tenure, and his presence will be missed."
