Abstract
System including an elongated member and a steering assembly that is connected to the elongate member, and which is configured to facilitate reconfiguration thereof. The elongated member includes a first segment and a second segment that is located distally of the first segment, wherein the second segment includes a stiffness that can be increased or decreased to reconfigure the elongated member via movement of a stiffening member.
Claims24
A system configured for use during a procedure, the system comprising:
- an elongated member including:
- a first segment;
- and
- a steerable segment located distally of the first segment;
- and
- at least one steering assembly operatively connected to the elongated member and configured to facilitate reconfiguration thereof, wherein a stiffness of at least a region of at least one steerable segment can be increased or decreased to increase or decrease resistance to bending.
The system of 2, wherein alternating stiffness in the region of the at least one steer segment will alter the effective length of the steerable segment to influence a radius of curve of the steerable segment.
