How It Works
How It Works
The valve-in-stent device consists of a flexure-based PDMS valve system secured within an hourglass-shaped, Nitinol stent. The valve diaphragm absorbs sound when the valve is sealed closed against the rigid body. The valve opens after deflection of the PDMS arms and allows for pressure equalization. The device maintains functionality over the long term and is delivered in a minimally invasive procedure.
