Estimating the term…
The present invention provides a modular prosthetic valve device having two or more device modules for percutaneous delivery unassembled at or near the valve implantation site and assembly at least in part using a self-assembly member, and a system and method of folding, delivering and assembling the device. The device modules may include a support structure and a valve module. The valve module has an unassembled, folded delivery configuration, and an unfolded, assembled (via the self-assembly member) working configuration. The valve module may be a single-piece leaflets substructure or a plurality of valve sections. The self-assembly member has a delivery configuration and may be reverted to a preset configuration for valve module assembly. The unassembled valve module may be rolled along its circumferential axis towards its height to a folded diameter equivalent to one rolled leaflet, providing a percutaneous valve device having a smaller delivery diameter than pre-assembled valve devices.
A modular percutaneous prosthetic valve device, comprising a plurality of device modules and a self-assembly member having a circumferential component, said device modules comprising a valve module, each of said self-assembly member and said valve module in a delivery configuration for mounting in a delivery device, the plurality of device modules having a folded, unassembled delivery configuration and said circumferential component of said self-assembly member having a substantially helical delivery configuration extending along a longitudinal axis of said delivery device and a preset working configuration;
A modular percutaneous prosthetic valve device, comprising a valve module and a self-assembly member, each in a delivery configuration for mounting in a delivery device, said valve module having a folded delivery configuration capable of unfolding for self-assembly and being assembled into a working configuration via said self-assembly member after deployment from said delivery device, said self-assembly member having a straight delivery configuration parallel to a longitudinal axis of said delivery device, wherein in the folded delivery configuration, the valve module is squashed to a flattened configuration.
