Claim 0:
1. 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, a distal portion of the sheath having in series from the distal end a first relatively rigid section, a first relatively flexible section, a second relatively rigid section, a second relatively flexible section and a third relatively rigid section, the first relatively flexible section being spaced apart from the second relatively flexible section such that the distal portion is deflectable to a dual hinged configuration, the first, second, and third relatively rigid sections being formed from a first polymer having a first Shore D hardness, and the first and second relatively flexible sections being formed from a second polymer having a second Shore D hardness less than the first Shore D hardness;
a pull wire having a distal end connected to the sheath distally of the first relatively flexible section and extending to a proximal end of the pull wire;
a plurality of mapping electrodes positioned at the distal end 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.
