Abstract
Procedures may be performed on the heart after the installation of a mitral valve fixation device. In order to prepare the heart for such procedures, the fixation device may be removed or disabled in minimally invasive ways (e.g., through an endovascular procedure), without requiring open access to the heart. The fixation device may be partitioned so that one portion may remain attached to each leaflet of the mitral valve. In another example, the leaflets may be cut along the edges of the distal element(s) of the fixation device, so as to cut the fixation device from the leaflet(s). Systems and devices for performing such procedures endovascularly are disclosed. Fixation devices with improved access to a release harness are also disclosed.
