Claim 13:
14. A delivery device for delivering a pacing lead to the His bundle of a patient's heart, the delivery device comprising:
a handle;
an elongated sheath having a proximal end connected to the handle and a distal end remote from the handle, the distal end having a distal tip, a distal portion of the sheath having a plurality of flexible sections spaced from one another along a length of the sheath;
a pull wire having a distal end connected to the sheath distally of the flexible sections and extending to a proximal end of the pull wire;
a plurality of mapping electrodes positioned at the distal end of the sheath, the mapping electrodes including two electrodes that diametrically oppose one another at a position spaced from the distal tip of the sheath,
an electrical conductor extending from each of the plurality of mapping electrodes; and
a tube extending along a length of the elongated sheath, wherein the electrical conductors extend through the tube,
wherein the distal portion of the sheath is deflectable within a deflection plane, and the two electrodes lie within the deflection plane when the distal portion of the sheath is deflected.
