After implantation of Esprit™ BTK, study participants will have their blood drawn on specific days for up to 60 days. After 60 days, when all blood draws are completed, you will have 7 study visits remaining over a 5-year period. Duplex ultrasound testing, to assess your leg arteries, will be conducted at 30 days, 180 days, and 1 year.
