The National Heart, Lung, and Blood Institute intends to award a sole-source purchase order to DMT-USA Inc. for one pressure myograph system to assess small arteries from mouse models. The system must include a pressure myograph chamber, interchangeable cannulas, a longitudinal force transducer, pressure transducers, microscope with camera, software, and supporting components, along with installation and training. The government identified DMT-USA as the only source capable of providing the complete integrated system, especially the required longitudinal force-measurement capability. Other systems reviewed lacked the full combination of vessel-size flexibility, force measurement, integrated transducers, microscopy, and compatible software. Delivery, installation, and training will be performed at an NIH facility in Bethesda, Maryland.

The National Heart, Lung, and Blood Institute intends to award a sole-source purchase order to DMT-USA Inc. for one pressure myograph system used to assess small arteries and blood vessels from mouse models. The system must support measurements of vascular compliance, stiffness, diameter, axial force, and pressure under near-physiological conditions, and include a pressure myograph chamber, cannulas, force and pressure transducers, microscope, software, and installation/training. The government identified DMT-USA as the only source capable of providing the required integrated longitudinal force-measurement capability, which other systems reportedly lacked. Delivery, installation, and training will be performed at an NIH facility in Bethesda, Maryland. The acquisition will apply Buy American and FAR Part 25 domestic preference requirements, and interested sources may submit quotations demonstrating their ability to meet all requirements.
