a remote tissue perfusion monitoring system to reduce amputations

### Pathophysiology and epidemiology of Peripheral Arterial Disease
PAD is a common disease of the vasculature estimated to affect **12mm** Americans, with the prevalence of CLI estimated to be approximately **2mm** and growing as the population ages with more comorbidities. With the diagnosis of CLI, a patient suffers from **poor perfusion of their legs and feet**. It can manifest as intense leg pain while at rest, a wound that will not heal, or a gangrenous limb. According to the American Heart Association and American College of Cardiologists, **evidence of hypoperfusion is a Class I indication for prompt surgical revascularization**
### Morbidity and Mortality
The Society for Vascular Surgery estimates that **within a year of being diagnosed with CLI, 25% of patients will be dead**, 30% will be alive but missing a limb due to amputation, 20% will be living with chronic CLI, while a mere 25% have resolution of their disease.

### The burden of disease
Vascular surgery is the dark cloud of the hospital with the greatest number of 30-day readmissions of any surgical specialty. The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) found that the **combined rate of readmission following endovascular and surgical revascularization of the lower extremities is 16% within the first month**. Occlusion is one of the most common complications driving readmissions. Complications due to occlusion are expensive, as they lead to additional surgical procedures and prolonged hospital stays. **One study estimated the cost of amputation at $18,600, endovascular revascularization at $17,100, and surgical revascularization at $40,100.**
