Abstract
Guidewires useful for cooperating with catheters may be actively steered and/or provide adjustable stiffness. Angle or curvature of a guidewire, and/or flexural modulus of a guidewire, may be adjusted at one or more locations between ends thereof. Variable stiffness segments may include electrically operated compressible and/or extensible materials. Multiple tensile elements may terminate at different body elements to adjust angle or curvature at multiple locations. Multiple circumferentially and/or radially contractible fiber regions may be provided and distributed over a length of a guidewire. Adjustable flexure elements arranged in or along a guidewire may be electrically operated. A flexible core member may be centrally arranged in a tubular body. A flexible guide wire or track may cooperate with electrically operable motor units.
