The Department of Veterans Affairs is seeking to procure Y-90 SIR Spheres microspheres for use in Selective Internal Radiation Therapy (SIRT) at the North Texas Medical Center in Dallas, Texas. This contract involves the purchase of five unit doses of Sie-Spheres Y90 resin microspheres, estimated at $17,750 per dose, to ensure the availability of this critical treatment for patients with liver tumors. The unique characteristics of these microspheres, provided solely by Sirtex Medical, are essential for delivering targeted radiation therapy, as they are designed to lodge in tumor arterioles while minimizing exposure to healthy tissue. Interested parties can contact Contract Specialist Robert Clark at robert.clark15@va.gov or by phone at 512-228-1088 for further details regarding this procurement, which is justified under FAR 13.106-1 and is expected to exceed the micro-purchase threshold but remain under the simplified acquisition threshold of $250,000.
