Claim Text:
1. A medical device, comprising: a catheter body having a first portion with a first plane of preferential bending, and a second portion with a second plane of preferential bending, the first portion being distal of the second portion; a single steering actuator coupled to the catheter body; a guide plate within the catheter body, the guide plate having a first outer edge, a second outer edge, a longitudinal axis, a width that extends directly from the first outer edge directly to the second outer edge and that is perpendicular to the longitudinal axis, a length that is located along the longitudinal axis, a proximal portion, a distal portion, and a transition portion, the guide plate proximal portion being configured to cause the second plane of preferential bending and the distal portion of the guide plate being configured to cause the first plane of preferential bending, the proximal portion 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 plate directly to the second outer edge of the guide plate, the distal section and the proximal section being linear and located along the guide plate longitudinal axis and an entirety of the middle section having an arc of curvature when the catheter body is in an at least substantially linear configuration; and a first steering member and a second steering member, each of the first and second steering members having a proximal end and a distal end, the proximal end of each of the first and second steering members being coupled with the single steering actuator, and the distal end of each of the first and second steering members being directly affixed to the catheter body, the medical device having a first and second mode of steering: in the first mode of steering, movement of the single steering actuator from an initial position is configured to cause the first portion to bend from an initial shape to a first arc shape along the first plane of preferential bending; and in the second mode of steering, movement of the single steering actuator from the initial position is configured to cause the first portion to bend from the initial shape to a second arc shape along the second plane of preferential bending.
