ATS Heart Valve

ATS Heart Valve

Usage conditions apply
Description (Brief)
Introduced in 1992 the ATS is a bileaflet or open pivot heart valve. ATS Medical was founded in 1992 by Manny Villafaña, and acquired by Medtronic Inc. in April 2010. One of it's unique features is that it significantly lowers the sound levels caused when the occluder strikes the orifice as the valve closes. This became one of its selling points to doctors and patients. Many recipients of heart valves find the clicking noise of their prosthetic to be annoying and interfering with their sleep.
