US patent issued for implantable LVAD with wave membrane technology


CorWave obtained patent no. US 9,968,720 B2 on May 15, 2018 from the United States Patent and Trademark Office.

Titled “Implantable pump system having an undulating membrane,” the patent describes the application of CorWave’s technology for blood pumping in a left ventricular assist device (LVAD), and specific designs related to using the wave membrane technology to make a blood pump. The term of this patent extends into 2037. A corresponding PCT international application is also pending.

This patent further completes CorWave’s extended IP portfolio across four patent families. Unlike other LVAD on the market today, CorWave wave membrane technology is able to mimic a pulse and produce blood flow velocity similar to that of a natural heart. Closer to the natural functioning of the heart, CorWave pumps have the potential to drastically reduce the risk of complications and costs associated with them.

“This is a significant milestone for the company and the R&D group. We have been working hard at the forefront of the technological frontier to bring CorWave’s novel pumping technology to the LVAD space. The receipt of this patent reinforces the unique nature of the wave technology.” comments Carl Botterbusch, CorWave CTO.

“CorWave is a company with global ambitions. Having a patented system in the US is a requirement to bring the expected benefits of CorWave’s technology to American patients and clinicians. Thousands of American patients are already supported by LVADs and the US is home to numerous clinical centers of excellence that have been pioneering the LVAD field for decades.” explains Louis de Lillers, CorWave CEO.
