Deep vein thrombosis (DVT) is the formation of a blot clot in the deep veins, particularly the lower limbs. Bed-bound patients such as post-surgical hospitalized individuals are at a particularly increased risk of developing these clots. 
DVTs can dislodge, reaching the pulmonary vasculature resulting in potentially life threatening pulmonary embolisms. Common prophylaxes include early ambulation, compression devices, and/or anti-coagulation therapy. A new device, Geko by UK based Sky Medical, is a wristwatch sized product that stimulates the peroneal nerve via electrical signals leading to muscle activation of the lower limb, that has shown evidence of increased blood-flow in the femoral vein. Preventing venous stasis can potentially lead to less clot formation. The small self-adhesive device is applied to the posterior knee with no need for wires or leads. If proven effective, this can potentially alter current DVT prophylactic therapy. Geko is CE Marked under the Medical Devices Directive. The device is currently not approved by the FDA and not available for sale in the USA.
