FUS Instruments

The National Institute of Mental Health (NIMH), part of the Department of Health and Human Services' National Institutes of Health, has issued a Notice of Intent to Sole Source for the acquisition of a Stereotactic Focused Ultrasound system (RK-50) from FUS Instruments Inc. This Special Notice announces the agency's plan to conduct a non-competitive procurement for specialized scientific research equipment designed for preclinical applications in mice and rats. The notice is classified under NAICS code 811210 for Electronic and Precision Equipment Repair and Maintenance and is designated as a total small business set-aside opportunity. The solicitation number is NIMH25007631, and the acquisition covers a one-year base period from September 1, 2025, to August 31, 2026. The system includes advanced components such as a three-axis motorized positioning system, custom treatment planning software, RF driving electronics, and specialized transducers.

The primary purpose of this acquisition is to procure a highly specialized ultrasound system capable of supporting research in blood-brain barrier permeability modulation, neuromodulation, and sonodynamic therapy applications. Interested contractors must submit capability statements electronically to contract specialist Joe Kennedy by August 7, 2025, at 12:00 PM EST, though the government has already determined that FUS Instruments Inc. is the only vendor capable of providing the required services. All potential respondents must maintain active registration in the System for Award Management (SAM) and must include specific details in their submissions such as unit pricing, manufacturing location, and business size certification. The opportunity is restricted to small businesses under the $34 million size standard for the applicable NAICS code. While the notice allows for capability statements from other vendors, the sole source nature indicates that the government has conducted market research and concluded that only FUS Instruments possesses the unique capabilities necessary to fulfill this specialized research requirement.
