Sky wins FDA clearance to market the geko™ device for venous insufficiency and ischemia - a therapy area sorely in need of innovation.

DARESBURY, England, Dec. 16, 2021 /PRNewswire/ -- Medical devices company, Sky Medical Technology Ltd, has today announced U.S. Food and Drug Administration (FDA) 510(k) clearance to market the geko™ device for increasing microcirculatory blood flow in lower limb soft tissue of patients with venous insufficiency and/or ischemia.

The geko™ device is the first electrical neuromuscular stimulator of its kind to be cleared for increasing microcirculatory blood flow and adds to Sky's prior FDA clearances for edema reduction and for stimulation of the calf muscles to prevent venous thrombosis (blood clots) in both surgical and non-surgical patients.    

Venous insufficiency and ischemia relate to reduced blood flow in the veins and arteries. This can lead to lower extremity edema, skin changes, and discomfort. Venous insufficiency can progress to chronic venous insufficiency (CVI), a serious condition attributed to diminished quality of life and loss of work productivity. In most cases, the cause is incompetent valves. Each year approximately 150,000 new patients are diagnosed with chronic venous insufficiency, and nearly $500 million is used in the care of these patients. If venous insufficiency and ischemia are left untreated, progressive to CVI can lead to post-phlebitic syndrome and venous leg ulcers¹.

Three recent published studies, two led by Das^2,3, the other led by Bosanquet⁴ demonstrate geko™ device generated microcirculatory blood flow increase in the lower limbs of patients with venous insufficiency and ischemia. Both studies measured the increase using Laser Speckle Contrast Imaging, a non-invasive technique that measures blood flow.  

CEO and Founder Bernard Ross  said, "Achieving this latest 510(k) clearance is a significant milestone for Sky that will allow us to initiate a controlled market release of the geko™ device, to address venous insufficiency and ischemia in the first instance – a therapy area sorely in need of innovation. With this 510(k) and in partnership with leading US clinicians we can now press ahead to redefine  the way vascular related conditions can be treated."

The geko™ device is a non-invasive, easy to use, wearable therapy device. The size of a wristwatch and worn at the knee, the disposable device gently stimulates the common peroneal nerve activating the calf and foot muscle pumps, resulting in increased blood flow in the deep veins of the calf^5, at a rate equal to 60%⁶ of walking without a patient having to move. The device operates without external pressure to the leg and allows complete mobility.

The company is headquartered in the UK and backed by leading international investors in both healthcare and technology. The company is in the process of submitting further FDA 510(k) applications to expand its claims related to blood flow increase to address venous insufficiency.
