Modular percutaneous valve structure and delivery method
First Claim
1. A modular prosthetic percutaneous valve device, comprising a plurality of device modules, said device modules including a plurality of valve sections and a support structure, each valve section including a discrete valve leaflet, wherein each valve section has an unassembled delivery configuration, wherein each of said valve sections and said support structure are spatially separate from one another when delivered and wherein said valve sections directly connect together into a working configuration valve assembly after deployment from a percutaneous delivery device, wherein said support structure and working configuration valve assembly are combined into said valve device after deployment from said delivery device.

Abstract
A modular prosthetic valve device for implantation in a patient and a system for and method of delivering such a modular valve device and assembling it in vivo are disclosed. The valve device is designed as two or more modules to be delivered unassembled, spatially separate, and combined into an assembled valve device in the body at or near the site of implantation. The valve device of the invention is deliverable as modules, providing a smaller delivery diameter than pre-assembled percutaneous valves, permitting use of a delivery device of reduced diameter, and increasing the flexibility of the valve device during delivery, compared to percutaneous valve devices in the art. The modules of the valve device may be connected by pull wires for delivery sequentially, and then assembled by remote manipulation using the pull wires. Various locking mechanisms are provided for attaching the device modules together.
