Abstract
An expansion frame system for deploying medical devices in a patient's body cavity. The system typically includes an inner wire disposed within a lumen of an outer wire. Distal ends of the inner and outer wires are attached to a substantially circular frame at first and second points. During use, the outer wire is displaced relative to the inner wire, causing the circular frame to rotate about an axis perpendicular to the line defined by the first and second points. Medical devices, such as a filter, a stent, an occluder or a manometer, can be mounted on the circular frame. The diameter of the expansion frame can be varied to achieve optimal contact with the luminal wall of the body cavity. Methods of using the expansion frame system for temporary or permanent placement of a medical device is disclosed.
