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.
Claims15
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 make up 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 to control the relative movement between the valve member and device frame and select one position from a plurality of positions along a longitudinal axis of said valve device between said valve member and said device frame in said second configuration after delivery and deployment from a percutaneous delivery device.
A method of adjusting the position of a valve member of a percutaneous valve device comprising:
- providing a delivery device containing a percutaneous valve device, said valve device comprising a first adjustment structure on said valve member and a second adjustment structure on a device frame, wherein said valve member and said device frame together make up 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 with a configuration on said second adjustment structure in a complementary manner to permit controlled relative movement between the valve member and device frame;
- deploying said valve device from said delivery device and expanding said valve device to form said second configuration;
- adjusting a position of said valve member relative to a position of said device frame via said first and second adjustment structures, wherein said configurations of said first and second adjustment structures cooperate in a complementary manner;
- and
- selecting one position from a plurality of positions between said valve member and said device frame along a longitudinal axis of said valve device.
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 make up 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 to control the relative movement between the valve member and device frame and select one position from a plurality of positions between said valve member and said device frame;
- said apparatus being configured to allow adjustment of an angular position of said valve member relative to said device frame.
A system comprising:
- a percutaneous valve device, said valve device comprising a first adjustment structure on a valve member, and a second adjustment structure on a device frame;
- wherein said valve member and said device frame together make up said percutaneous 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 with a configuration on a second adjustment structure in a complementary manner to control the relative movement between the valve member and device frame and select one position from a plurality of positions along a longitudinal axis of said valve device between said valve member and said device frame in said second configuration;
- and
- a delivery device for percutaneously delivering and deploying said valve device.
