Abstract: An annuloplasty band and method of implantation. The band is shaped and sized to avoid the adjacent aortic valve structure and better protects against dehiscence along the muscular mitral annulus. The band is asymmetric and when implanted spans more around the side of the mitral annulus having the posterior commissure than the side with the anterior commissure. The band has a saddle shape with a posterior upward bow centered on a minor axis of the mitral annulus, and a span extending clockwise therefrom is longer than a span extending counter-clockwise. The longer span may be 150° while the shorter span extends 90°. A set of rings may have different saddle profiles and different plan view shapes for different sized bands. A method includes implanting so that the band extends over the posterior leaflet and a short distance past the posterior commissure outside of the anterior leaflet.

Abstract: The present disclosure relates generally to the field of medical devices for delivering artificial chordae tendineae in a patient. In an embodiment, an anchor is movable between a delivery configuration and a deployed configuration, the anchor being in the delivery configuration when disposed within a delivery catheter, the anchor being in the deployed configuration when the anchor is moved beyond a distal end of the delivery catheter. When the anchor is in the delivery configuration it has a first outer dimension and when the anchor is in the deployed configuration it has a second outer dimension, the first outer dimension being smaller than the second outer dimension. The anchor is engageable with a papillary muscle or a heart wall when the anchor is in the deployed configuration and is also coupleable to an artificial chordae tendineae to anchor the artificial chordae tendineae to the papillary muscle or heart wall.

Abstract: An implant localization device includes a coupler and a positioning system. The coupler is configured to removably engage an implant component to fix the positioning system in space relative to the implant component. The positioning system is in communication with a centralized computing system, whereby, due to the fixed spatial relationship between the positioning system and the implant component, via the coupler, and determinable changes in movement relative to a registered starting point, the centralized computing system is able to calculate a real-time position and orientation of the implant component. The centralized computing system is configured to synthesize data from a joint templating software program, a CAD software program, and the positioning system to provide real-time positional and orientation data to assist with extraction and placement of the implant component. Robotics and reference markers may be used to further automate and/or enhance the accuracy and efficiency of the system.
