Description of intervention(s) / exposure
Treatment: Devices - Capstan System transcatheter mitral valve replacement

Experimental: Implant - Participants who pass all screening criteria will undergo a percutaneous procedure for the implantation of a permanent mitral valve replacement device.

Participants will be followed for 5 years to evaluate safety and feasibility of Capstan Medical TMVR System for mitral valve replacement in humans with predominantly regurgitant mitral valves who are symptomatic and who are not good surgical candidates.


Treatment: Devices: Capstan System transcatheter mitral valve replacement
This is a first human use trial exploring a novel transcatheter mitral valve replacement implant and electro-mechanical delivery system. The device offers a minimally invasive repair for patients who have at symptomatic regurgitation who are otherwise ineligable for surgical intervention, or who have no other prospects for treatment and in whom medical therapy has already been optimised.
