Abstract

A delivery system for implanting medical devices within a lumen or body cavity of a patient, the delivery system having a wire formed from a plurality of layered strands yielding a reduced bending stiffness for improved maneuverability with no reduction in overall tensile strength compared to delivery systems using a single wire and of comparable diameter. The physical properties of the delivery system permit optimal placement and retrieval of an intracardiac occluder within a patient.
