System and method for assembling a folded percutaneous valve
First Claim
1. A valve module for a percutaneous modular valve device, comprising:
- a valve frame; and
a plurality of valve leaflets, said plurality of valve leaflets attached to said valve frame;
wherein said valve frame comprises a first ring member, a second ring member and a plurality of masts connected to and disposed between said first and second ring members, wherein one of said plurality of masts is a longitudinally split mast having a first mast half and a second mast half;
wherein said valve frame has a folded unassembled delivery configuration and is assembled into a working configuration after deployment from a delivery device;
wherein said first and second ring members are substantially collinear with said masts in said folded unassembled delivery configuration.

Abstract
The invention provides a multi-component (modular) percutaneous valve device that includes a valve module having valve leaflets and a valve frame. The valve frame includes one or more, for example two, ring members and a plurality of masts. Also provided is a valve frame having specially designed pivot points at the connection between masts and first and second ring members to assist folding the valve module and minimizing delivery diameter. The valve frame may also include wire guides to facilitate combining the valve module with a support module. The masts or a ring of the valve frame may also include locking members, such as shafts for closing the valve module and securing the valve module to the support module. The support module includes corresponding locking members, such as spears that align with the shafts on the valve module for assembly and locking the valve module to the support module.

26. A modular percutaneous valve device comprising:
-
a valve module, said valve module including a valve frame and a plurality of valve leaflets attached thereto, said valve frame including at least one ring member and a plurality of masts connected thereto, wherein said valve module has a folded unassembled delivery configuration and an assembled working configuration, each ring member having a substantially straight delivery configuration with a first end and a second end;
wherein in said folded unassembled delivery configuration each ring member extends in the same general direction as said plurality of masts, said plurality of masts substantially orthogonal to said ring member in said assembled working configuration;a support module, said support module having a compressed delivery configuration and an expanded working configuration; a plurality of sets of locking members designed to lock said valve module to said expanded support module, each set of locking members comprising a spear and a corresponding shaft having a lumen, wherein said spear has a first spear end and a second spear end, and a spearhead at said first spear end, said spearhead including an eyelet and an elongated aperture; and a plurality of wire guides located on said ring member. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
