Method and apparatus for fine adjustment of a percutaneous valve structure

摘要

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.

主权项

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.
