Abstract
A medical device is movable between first and second positions. The medical device has an actuator which is movable between a relaxed position and a stacked position. The stacked position of the actuator deforms the medical device toward the stacked position of the actuator. When the actuator is in the relaxed position, the shape of the medical device is primarily determined by the shape of a main element.

A method of changing the shape of a medical device in a patient, comprising the steps of:
- providing a medical device having a main element and an actuating element, the main element being movable between expanded and collapsed positions, the main element being naturally biased toward the expanded position, the actuating element extending around the main element and being movable relative to the main element between a stacked position and a relaxed position;
- delivering the main element into a patient with the main element in the collapsed position, the main element being held in the collapsed position by the actuating element, the actuating element being in the compressed position;
- moving the actuating element to the relaxed position thereby permitting the main element to move toward the expanded position.
A medical device which is movable between a first shape and a second shape, the medical device comprising:
- a first elongate member;
- and
- a second elongate member which assumes a predefined shape when placed under compression;
- wherein the first and second elongate members are coupled to one another at least one location so that the first member may be tensioned to compress the second member and cause the first and second members to assume the predefined shape.
