Cardiovascular disease is the leading cause of death in the United States, but there is limited availability of autologous vessels for bypass procedures. With the use of natural materials, such as leatherleaf viburnum and gelatin, a successful plant derived vascular graft was developed. Ultrasound imaging was used to assess the patency of the plant vascular graft through both doppler and PDI imaging. Ultrasound imaging enables a non-invasive, and non-destructive way to assess measurements, patency, and flow velocity of the plant derived vascular graft. The plant vascular graft was embedded in a novel vascular phantom consisting of optical and mechanical properties that mimic the behavior of human tissue for optimal ultrasound imaging.
