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, wherein said first adjustment structure is configured to fit together with said second adjustment structure in one of a plurality of predetermined positions within a range of relative positions between the valve member and device frame;
said apparatus being configured to allow adjustment of one or both of a longitudinal position of said valve member independently of and relative to said device frame and an angular position of said valve member independently of and relative to said device frame.

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.
