Laser Associated Sciences’ non-invasive blood flow monitoring system, FlowMet-R, received 510(k) clearance from the FDA for detecting peripheral artery disease and gauging the efficacy of treatments.

The device clips onto a patient’s toe and uses a small laser diode and camera to measure blood flow, providing insight on surgical effectiveness.

"By directly measuring limb perfusion during surgeries, physicians can see for the first time whether peripheral blood flow [is] being improved in real time,” says Laser’s CEO Sean White. “This reduces the ambiguity that clinicians currently face in knowing not only if an intervention is effective, but how effective it is.”
