1. An apparatus for delivering a prosthetic heart valve to a body lumen, comprising:
- a delivery catheter comprising a tube and a gripper, the tube having a plurality of slots and the gripper having a plurality of fingers;
a prosthetic heart valve having a support structure comprising a plurality of folded panels and being coupled, in a contracted state, with the gripper;
wherein relative rotation between the tube and the gripper causes the plurality of folded panels to move through and radially extend outward from the plurality of slots of the tube,wherein longitudinal movement of the gripper relative to the tube causes the folded panels to slide out of the slots, andwherein relative motion between the gripper and the prosthetic heart valve causes the prosthetic heart valve to be released from the fingers of the gripper.
