1. An assembly comprising:
an implantable device comprising:
a frame;
one or more expansion features coupled to the frame, wherein rotation of the expansion features causes the frame to move between an expanded state and a collapsed state; and
one or more tissue penetrating members extending from an end of the frame, each of the tissue penetrating members having:
a first penetrating surface,
a second penetrating surface,
a delivery configuration in which the first and second penetrating surfaces abut to shield each other in a manner that makes the tissue penetrating member blunt, and
a tissue penetrating configuration in which the penetrating surface is exposed in a manner that makes the tissue penetrating member sharp; and
a delivery apparatus comprising a delivery catheter, and configured to:
deliver the implantable device in the collapsed state to a native heart valve while the one or more tissue penetrating members are in the delivery configuration,
at the native heart valve, transition the one or more tissue penetrating members into their tissue penetrating configuration by moving the first and second penetrating surfaces away from each other, and
while the one or more tissue penetrating members remain in their tissue penetrating configuration, cause the one or more tissue penetrating members to embed into native tissue adjacent the native heart valve by forcing the first and second penetrating surfaces into the tissue.
