Overview
Brief Summary
This is a prospective, controlled, single-arm clinical investigation for the treatment of subjects with severe symptomatic aortic valve stenosis using Valvosoft® Pulsed Cavitational Ultrasound Therapy (PCUT) - First-In-man
Detailed Description
CARDIAWAVE has developed a new non-invasive, real-time image-guided, therapeutic approach to treat patients suffering from Calcified Aortic Stenosis. CARDIAWAVE's Valvosoft device is a new ultrasound therapy based on a disruptive technology involving delivering an extremely precise and focused ultrasound beam to perform a reparative effect on the aortic valve leaflets, softening the valve's tissues, restoring leaflet mobility, and therefore improving the overall clinical status related to the aortic valve stenosis. This is a FIM study
