This is a firm fixed-price purchase order awarded by the Department of Veterans Affairs' Network Contracting Office 19 to Sirtex Medical Inc., a for-profit medical device manufacturer. The contract, valued at $86,500.00, is for the supply of up to 16 doses of Y-90 resin microspheres and associated accessories used in selective internal radiation therapy (SIRT) to treat liver tumors and metastatic colorectal cancer. The contract supports the procurement needs of the Oklahoma City VA Medical Center. This sole-source award was not set aside for small businesses. Sirtex Medical Inc. has a history of providing specialized medical devices, particularly Y-90 microspheres, to federal healthcare agencies like the VA and the Defense Health Agency through a variety of contract vehicles. This specific award appears to be a standalone purchase order, not associated with a larger contract vehicle.
