摘要
A novel multi-stage and multi-lumen (MSML) delivery and implantation system for implanting a prosthetic heart valve for treatment of a diseased heart valve. The MSML delivery system comprises of a docking system, a dual-guiding-and-fixation (DGF) system for implanting a plurality of DGF members in the proximity of the annulus, a valve delivery system for releasing and locking a prosthetic valve, and a prosthetic valve having a crescent shaped stent, a plurality of DGF members, a plurality of leaflets comprising a free edge, two commissure attachment regions, an attachment edge, a coaptation region, a belly region, and at least one prong structure. The docking system, the DGF system, and the valve delivery system are configured cooperatively for advancing to an operative position, and for delivering and implanting a plurality of DGF head members to the operative position, and for guiding, delivering and fixating the prosthetic valve to the operative position.
