Detailed Description
The Tioga TMVR Feasibility Study is a prospective, single-arm, multi-center study with a planned enrollment of up to 30 patients.
The Tioga TMVR System is designed to percutaneously replace a patient's diseased native mitral valve with a bioprosthetic valve.
The investigational device is intended for transseptal replacement of the mitral valve in patients with symptomatic MR (MR>=3+).
