Monitoring Local Tissue Oxygen Changes Using the Wireless Lumee Oxygen Platform in Correlation to TcPO2

Open to people ages 18 years and up

A suitable candidate must meet the following criteria:

• Male or female must be ≥ 18
• Diagnosed with PAD, Rutherford 3 or 4, stable at time of enrollment (stable disease state)
• No active infection

• Known history of keloids, excessive fibrosis during wound healing
• Known allergies to Lumee™ Oxygen hydrogel components, local anesthetic agents, suture materials, or severe skin allergies to adhesives
• Any skin or musculoskeletal condition or deformity limiting injection of the Lumee™ Oxygen hydrogel or preventing subsequent attachments of the Lumee™ Patch system
• Any skin modification in the area of injection that would potentially influence device performance (for example tattoos or scars)
• No previous amputation related to the affected limb
• Significant venous insufficiency resulting in swelling of the lower leg, ankle or foot or chronic venous stasis changes (CEAP clinical score ≥ 3)
• Any condition that at the discretion of the investigator, physician or designee will impact the safety of the subject or the scientific integrity of the trial
• Female subjects of childbearing capacity (not surgically sterile or menopausal for ≥ 1 year)
• Participation in another clinical study, that would potentially interfere with the participation in this study
• Subject requires dialysis
• Subject is receiving immunosuppressive therapy
• Subject has incompressible arteries tested by occlusion test in the arm
• Inability to obtain consent
