Abstract
In one embodiment, a delivery apparatus handle, such as for a mechanical heart valve frame can comprise an actuation knob with a toggle mechanism that can toggle the actuation knob from a first state in which the actuation knob is operable to cause the linear or rotational movement of multiple elements or sets of elements, such as tubes that are attached to, e.g., a mechanical heart valve frame to cause expansion or collapsing of the frame, to a second state in which only a single element or set of elements is moved, allowing for additional operations, such as, e.g., locking the frame and/or releasing it from the delivery apparatus.
