The government intends to award a sole source firm-fixed-price purchase order to Sirtex Medical Inc. for SIR-Spheres Y90 Resin Microspheres and associated accessory kits, including delivery domes and sets. The required supplies will be delivered to the Bay Pines VA Health Care System. This notice is not a request for competitive proposals; the items are proprietary and only one source is available. Interested parties may submit a capability statement, including evidence of authorization to distribute the products if not the manufacturer, to be considered for a potential competitive procurement. Any response will be reviewed at the government's discretion before proceeding with the sole source acquisition.
