1. A delivery system for endovascularly implanting a valve repair device at a mitral valve, the delivery system comprising:
a delivery catheter having a distal portion configured to be endovascularly delivered to a left atrium, wherein the distal portion is configured to hold the valve repair device in a delivery state;
a hub shaft extending through the delivery catheter, the hub shaft having a proximal portion and a distal portion;
a hub assembly coupled to the distal portion of the hub shaft, wherein—
the hub assembly includes an inner hub component that is movable relative to an outer hub component between a first position, a second position, and a third position,
in the first position, the hub assembly is configured to secure a first end portion of the valve repair device between the inner and outer hub components,
movement of the inner hub component from the first position to the second position is configured to release a first side portion of the first end portion of the valve repair device, and
movement of the inner hub component from the second position to the third position is configured to release a second side portion of the first end portion of the valve repair device to release the first end portion from the hub assembly; and
a core shaft extending through and independently movable with respect to the hub shaft, the core shaft having a plug assembly configured to releasably engage a second end portion of the valve repair device.
