    Abstract: A steerable catheter includes a catheter shaft having a lumen defined by a catheter wall, a proximal portion, a distal portion, and a length extending therebetween, and at least one pullwire extending along the length of the catheter shaft and coupled to the catheter wall. The at least one pullwire has a proximal section extending along the proximal portion of the catheter shaft in a first radial position, a distal section extending along the distal portion of the catheter shaft in a second radial position, and a transition zone connecting the proximal section and the distal section. The second radial position is offset circumferentially from the first radial position.

    Abstract: A steerable device and system allowing a steerable elongate member positioned within another steerable tubular elongate member to be steered independently of the steerable tubular elongate member. The steerable tubular elongate member may be steered in a first plane, bending the steerable elongate member therein in the first plane as well. A steering mechanism operatively associated with the steerable elongate member has a distal portion operatively associated with a steerable region of the steerable elongate member to steer such steerable region within a second plane transverse to the first plane. The steering mechanism is independently movable with respect to a portion of the steerable elongate member proximal to the steerable region so as not to affect the orientation of the steerable region to be steered into a second plane transverse to the first plane.

    Abstract: An elongate medical device is adapted to provide adjustable flexibility. The elongate medical device includes an inner coil having one or more inner coil filars extending in a first direction, and an outer coil having one or more outer filars extending in a second direction. A hypotube extends proximally from the inner coil and the outer coil. A cable extends through the inner coil and through the hypotube, where a distal end of the cable, a distal end of the inner coil and a distal end of the outer coil are all secured together at a distal end of the elongate medical device, such that applying a tensile force to the cable, relative to the hypotube, causes the inner coil and outer coil in combination to increase in stiffness.
