Vascular ultrasound system control unit

A vascular ultrasound system control unit is an AC-powered external device, possibly with internal rechargeable batteries, designed to work with a dedicated probe or catheter to detect and indicate blood flow in peripheral vessels using ultrasound, Doppler, or transit time technology. It is used clinically to identify and evaluate vascular flow restrictions such as clots, stenosis, or mechanical damage, or to monitor blood flow during microvascular surgical procedures.

Devices in this category are regulated as external medical devices that require connection to a separate probe or catheter to function. They are supplied as standalone control units and are intended for use with compatible, dedicated accessories that are not included with the unit.
