The purpose of this study is to monitor changes in local tissue oxygen levels in participants with Peripheral Artery Disease (PAD) using the Wireless Lumee Oxygen Platform. A transcutaneous oxygen pressure (TcPO2) device is used to show correlations in oxygen dynamics. Oxygen dynamics are induced by a pressure cuff and position maneuvers. Study participants will participate in the study for 12 months with six (6) planned visits over the course of the study. The investigational device, the Wireless Lumee Oxygen Platform, consists of the Lumee Oxygen, a sterile soft injectable oxygen-sensitive hydrogel, designed to sense and report oxygen levels in the subcutaneous tissue. After initial insertion of the hydrogel in the subcutaneous tissue using the Lumee Pen (a sterile disposable injector device), tissue oxygen levels can be monitored continuously using the Lumee Patch (a non-invasive, non-sterile, wireless electronic device to collect, analyze and report tissue oxygen levels sensed by Lumee Oxygen Hydrogel) attached to the skin through the Lumee Patch Adhesive (designed to adhere the Lumee Patch). The Lumee Patch sends collected tissue oxygen data to the Lumee App which displays the collected data and operates up to four Lumee Patches.
The goal of this observational study is to learn if the measures of tissue oxygenation from the MIMOSA Pro imaging device correlate to standard vascular assessment tools in patients who receiving a lower extremity vascular assessment. The main questions it aims to answer are: * Do the MIMOSA Pro tissue oxygenation measures correlate to Ankle-Brachial Index, Toe-Brachial Index, transcutaneous oximetry, and Doppler wave forms? * Do the MIMOSA Pro tissue oxygenation measures correlate with disease classifications for peripheral arterial disease, venous disease, and wound stage? * Is the MIMOSA Pro able to measure vascular status more often than other modalities? Participants will be asked to follow standard of care, and also allow for their legs to imaged by the MIMOSA Pro.
