FDA has cleared a Sky Medical Technology 510(k) for its geko device for stimulating the calf muscles to prevent venous thrombosis in non-surgical patients at risk for venous thromboembolism (VTE). Previously, the device was cleared for immediate post-surgical stimulation of calf muscles to prevent VTE, increasing blood circulation and edema reduction.

The battery powered, wearable device is the size of a wristwatch and worn at the knee, according to the company. It is intended to gently stimulate the common peroneal nerve activating the calf and foot muscle pumps, which results in increased blood flow in the calf’s deep veins.

The clearance was based on data from a study in acute stroke patients that showed 0% VTEs in patients wearing the device alone, compared to VTEs in the various control groups prescribed sequential compression devices at 2.4% or pharmacological prophylaxis at 1.1%, Sky Medical says.
