1. A delivery system configured for release and recapture of an implant, the delivery system comprising:
a plurality of tethers;
a torqueing manifold located on a distal end of a manifold shaft, wherein the torqueing manifold is:
configured to retain a first end of each of the plurality of tethers;
located radially inwards of a self-expanding replacement heart valve; and
located within a lumen of a locking shaft;
a plurality of engagement pins each configured to move from a locked position to an unlocked position, each of the plurality of engagement pins configured to releasably retain a second end of each of the plurality of tethers;
the self-expanding replacement heart valve having a plurality of eyelets, each of the plurality of tethers extending through a corresponding one of the plurality of eyelets;
wherein translation of each of the plurality of engagement pins from the locked position to the unlocked position releases the second end of each of the plurality of tethers and the replacement heart valve from the delivery system;
wherein rotating the manifold shaft tightens the plurality of tethers to crimp a distal end of the replacement heart valve to recapture the replacement heart valve following release of the replacement heart valve; and
an outer elongate hollow member shaft configured to cover the replacement heart valve when the replacement heart valve is in a collapsed state so as to facilitate recapture of the replacement heart valve following release of the replacement heart valve.
