Abstract: A bi-directional steerable catheter may include a handle and an elongate sheath extending distally from the handle. The handle includes an axial translation mechanism. A first steering wire extends through the elongate sheath from the handle to a distal pull ring. A second steering wire extends through the elongate sheath from the handle to the distal pull ring, the second steering wire being disposed on an opposite side of the elongate sheath from the first steering wire relative to a central longitudinal axis. The first steering wire is configured to engage with the axial translation mechanism to bend a distal portion of the elongate sheath in a first direction. The second steering wire is configured to engage with the axial translation mechanism to bend the distal portion in a second direction opposite the first direction. A tensioning member couples a proximal end of the first steering wire to the handle.
