Method and apparatus for fine adjustment of a percutaneous valve structure
First Claim
1. An apparatus for adjusting the position of a valve member of a percutaneous valve device, comprising:
- a first adjustment structure located on said valve member; and
a second adjustment structure located on a device frame;
wherein said valve member and said device frame together comprise said valve device, said percutaneous valve device having a first configuration for percutaneous delivery and a second configuration as a working configuration; and
wherein said first adjustment structure has a configuration that fits together in a complementary manner with a configuration on said second adjustment structure within a range of relative positions between the valve member and device frame;
said apparatus configured to allow adjustment of an angular position of said valve member relative to said device frame;
wherein said valve device is a modular valve device, said valve member and device frame being configured to be delivered separately and assembled into said valve device after deployment from said delivery device.

Abstract
The invention provides a device for fine adjustment of a prosthetic valve device and a method of adjusting the position of a prosthetic valve after implantation. The adjustment mechanism includes complementary structures on a valve member and device frame that cooperate to provide relative axial and/or angular motion between the valve member and device frame (and thus the native vessel). The adjustment mechanism of the invention may also include a means for selectively maintaining the relative position of the valve member and device frame. The device and method are particularly applicable for use with a modular prosthetic valve device that is assembled in the body lumen.
