Methods and devices for changing the shape of a medical device
First Claim
Patent Images
1. 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 actuating element being movable between a stacked position and a relaxed position, the actuating element moving from the relaxed position to the stacked position upon application of a compressive force to the actuating element, the main element being deformed from a first position to a second position by the actuating element as the actuating element moves to the stacked position, the actuating element being a coil wrapped around the main element;
introducing the medical device into a patient;
moving the actuating element between the stacked and relaxed positions thereby moving the actuating element between the first and second positions.

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.
