The Department of Veterans Affairs, through the Veterans Health Administration's Network Contracting Office 16, intends to award a sole-source contract for six L15 High-frequency Ultrasound Imaging Probes necessary for open-heart surgeries at the Michael E. DeBakey VA Medical Center in Houston, TX. This procurement is urgent due to the expiration and impending capacity limits of existing probes, which are critical for reducing risks associated with aortic disease during surgical procedures. Medistim USA Inc. has been identified as the sole vendor capable of fulfilling this requirement, and interested parties who wish to contest this decision must submit letters of interest by August 12, 2025, demonstrating their technical capabilities and rationale for competition. For further inquiries, interested parties may contact Contracting Officer Joseph Warren at joseph.warren@va.gov.
