Claim Text:
1. A medical device, comprising: a catheter body defining a proximal portion and a distal portion, the distal portion including a plurality of adjacent segments having alternating relative flexibilities; a guide member within the catheter body, the guide member defining a first outer edge, a second outer edge, a longitudinal axis, a width that is perpendicular to the longitudinal axis and extends directly from the first outer edge of the guide member directly to the second outer edge of the guide member, a length that is located along the longitudinal axis, a first segment having a first plane of preferential bending, a second segment having a second plane of preferential bending substantially perpendicular to the first plane of preferential bending, and a transition portion between the first segment and the second segment, the first segment having a distal section, a proximal section, and a middle section located directly between the distal section and the proximal section, the middle section having a width that extends directly from the first outer edge of the guide member directly to the second outer edge of the guide member, the distal section and the proximal section being linear and located along the guide member longitudinal axis and an entirety of the middle section having an arc of curvature when the guide member is in an at least substantially linear configuration; a steering actuator coupled to the proximal portion of the catheter body; a first steering element having a first end attached to the steering actuator and a second end attached to the distal portion of the catheter body at a first position; a second steering element having a first end attached to the steering actuator and a second end attached to the catheter body at a second position distal to the first position; and an electrode array disposed on the distal portion of the catheter body.
