Brief Summary:
Feasibility, usability and safety clinical study that is aimed at testing of the non-invasive VOTIS PedCheck system for measurement of changes in absorption of light in order to derive changes in perfusion and oxygen levels in the foot.
Detailed Description:
Introduction:
Peripheral Arterial Disease (PAD) affects 8-12 million people in the United States, and approximately 230 million worldwide. When linked with diabetes, PAD results in over 71,000 amputations annually.
Patients with PAD have decreased lower extremity arterial perfusion which is commonly referred to as "poor circulation." In most cases of PAD, atherosclerotic plaques narrow the arterial flow lumen which restricts blood flow to the distal extremity. This condition is characterized by progressive vessel obstructions, associated with cardiovascular (CV) events, including myocardial infarction (MI), stroke, limb ischemia, and CV death. Although PAD is a prevalent condition, it is still considered as an underdiagnosed manifestation of atherosclerosis. PAD is one of the most common vascular complications of diabetes, and can cause foot ischemia which is associated with non healing wounds, gangrene and amputations. At present there is no gold standard or test/device to identify, evaluate, and monitor the circulatory health of the foot in a reliable and precise way. In addition, calcification of blood vessels in patients with diabetes complicates the evaluation of perfusion in the foot. Since diabetes has reached epidemic proportions (60M people affected in Europe), there is an urgent need for additional measurement tools for assistance for the evaluation of PAD complications.
The current study is aimed at feasibility, usability and safety testing of the non-invasive VOTIS PedCheck system as an assessment tool of PAD. The protocol allows for 30 PAD patients and 30 self assessed healthy controls.
Objectives:
* To assess the safety of the PedCheck device using HOVR technology
* To calibrate the measurement of changes in absorption of light in order to derive relative perfusion and oxygen levels in the foot.
* To compare between PAD and non-PAD populations using HOVR.
Secondary objective:
• To collect data regarding the usability of the PedCheck device.
Description of investigational product:
Votis PedCheck portable device comprises patches affixed to the foot with encased laser diodes and photodetector sensors that automatically measure absorption of the light. Via lightweight leads, the patches link to a central control and display device. In addition an inflatable blood pressure cuff is placed above the knee. The control device sets the inflation and deflation of the cuff according to the protocol.
