This is a 15 patient pilot study to evaluate efficacy and safety of use of the Flowaid device in increasing local circulation in the legs of patients with Peripheral Vascular Disease. Patients will be evaluated and scored prior to treatment and then treated with the Flowaid device for a period of two hours. During the treatment period patients will be continuously monitored by digital thermograph as well as by tcPO2 and Laser Doppler Flowmetry. Patients will also be monitored for a brief period immediately after cessation of treatment to evaluate continued effect of the device on local circulation in the leg.

The study will be individually controlled with each patients treated leg evaluated against the contralateral non- treated leg.

Subjective data including distance able to walk, pain and vibratory sensation threshold will also be collected and evaluated appropriately.
