摘要：
Systems and methods for introducing and driving flexible members in a patient's body are described herein. In one embodiment, a robotic method includes positioning a flexible elongated member that has a preformed configuration, wherein at least a part of the flexible elongated member has a first member disposed around it, and wherein the first member includes a first wire for bending the first member or for maintaining the first member in a bent configuration, releasing at least some tension in the first wire to relax the first member, and advancing the first member distally relative to the flexible elongated member while the first member is in a relaxed configuration.
