What Founders Say

“The SIEGEL valve is a promising technology and has received enthusiastic feedback from physician investigators for its less invasive delivery, nickel-free construct, precise placement resulting from a lack of foreshortening and excellent hemodynamics.”

— Jay Yadav, M.D., Founder & CEO, MiRus 1
