    摘要: An apparatus is provided for positioning a core member within a passageway formed in a body. The apparatus includes at least one positioning element and a control mechanism for moving the positioning element relative to a core member. The positioning element includes a pair of end portions appended to the core member and a flexible central portion intermediate the end portions for movement relative to the core member. The positioning element is configured so that the flexible central portion moves in response to a stimulus from the control mechanism to assume a predetermined position engaging an interior wall of the body passageway and thus biasing the core member into a selected orientation within the passageway.
