Aortic Valve Stenosis
Conditions
Brief summary
A prospective, multicenter, single-arm study aimed to demonstrate safety and performance of the Leaflex™ Performer in the treatment of symptomatic severe aortic stenosis.
Detailed description
A prospective, multicenter, single-arm study aimed to demonstrate safety and performance of the Leaflex™ Performer in the treatment of symptomatic severe aortic stenosis. Subjects will be seen at pre- and post procedure, discharge, 30 days and at 3, 6, 9 and 12 months post procedure.
Interventions
A transfemoral catheter designed to treat calcific aortic stenosis by scoring the calcification in the aortic valve leaflets.
