Microvascular

Microsurgical Flowprobes
Transonic® Microsurgical Flowprobes work with HT350- and HT360-Series Flowmeters to measure
volume flow in vessels or grafts from 0.4 to 3.7 mm diameter. Flow measurement in these vessels
during microvascular procedures can guide better surgical decisions and give the surgeon
the opportunity to correct otherwise undetectable flow restrictions before closing the patient.

The AureFlo®
Transonic’s AureFlo system and Microvascular Flowprobes use
transit-time ultrasound technology to measure volume flowin micro-vessels with unprecedented accuracy and resolution.
Even lymph flows can be measured directly.
Used with single or dual-channel Optima Flowmeters, theAureFlo’s unprecedented resolution is accompanied by lower
offsets, and higher low-flow accuracy.
The AureFlo features an easy-to-read, high contrast display on
a touch screen PC. The display can be projected to an OR monitor.
Data entry to capture, store and retrieve flow informationis quick and easy. Operative notes can be easily augmented
and 8-second snapshots of recorded measurements can bereviewed from a remote location. Waveforms for reference,analyzing, teaching or, for the patient record, can be selected
and printed.
The AureFlo’s small footprint allows for easy mobility within
the OR. A stable cart securely holds the system components
and a convenient writing surface and storage drawer is also
provided.
The AureFlo’s immediate, quantitative flow measurements
provide unsurpassed accuracy and resolution to ensure vessel
patency in micro-vessels.
The AureFlo® system accommodates Transonic’s new
Microsurgical Flowprobes to continuously measure,display, record and document absolute volume flow
and other derived parameters. In the photo on theright, the AureFlo is shown with a HT354 singlechannel Optima Flowmeter, and displays the flow
profile of a popilteal artery.
