Self-assembling modular percutaneous valve and methods of folding, assembly and delivery

A modular percutaneous valve device, comprising:

• a folded valve module for mounting in a delivery device, and capable of unfolding for assembly after delivery to an unfolded, substantially flat unassembled configuration, having a base, apex, circumferential axis and a height axis extending from the base to the apex, and a folded configuration rolled in the direction of said height axis from the base to the apex or the apex to the base.

A method of folding a valve module of a modular valve device for delivery in a percutaneous delivery device comprising:

• providing a valve device that when substantially flattened has a base, apex, height axis extending from the base to the apex and a circumferential axis;
• folding said valve module in a manner selected from the group consisting of:
• rolling said unassembled, substantially flattened valve in the direction of said height axis, and squashing said valve module prior to loading into said delivery device.

A self-assembly member for assembling a valve module of a modular prosthetic percutaneous valve device after deployment from a delivery device, wherein said self-assembly member is selected from a group consisting of a wire, a band or a strip and has a delivery configuration and a preset configuration, and wherein when in said preset configuration said self-assembly member comprises a ring portion, and in said delivery configuration said ring portion opens up to extend in a generally linear direction along the longitudinal axis of said delivery device.

A modular percutaneous prosthetic valve device, comprising:

• a folded valve module, said folded valve module having a folded, delivery configuration, wherein said folded valve module is capable of unfolding for assembly after delivery from a delivery device to an unfolded, substantially flat unassembled configuration;
• and
• a self-assembly member for assembling said folded valve module after delivery from said delivery device, said self-assembly member selected from a group consisting of a wire, a band, or a strip and having a delivery configuration and a preset configuration, wherein when in said preset configuration said self-assembly member comprises a ring portion, and in said delivery configuration said ring portion opens up to extend in a generally linear direction along a longitudinal axis of said delivery device.

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 comprising a ring portion in said working configuration, said self-assembly member having a straight delivery configuration parallel to a longitudinal axis of said delivery device, and the valve module is in a squashed configuration when in the folded delivery configuration.
