A delivery device for delivering a pacing lead to the His bundle of a patient's heart includes an elongated sheath having a distal end, and a plurality of mapping electrodes positioned at the distal end. The distal end of the sheath may have a distal tip, and the mapping electrodes may include two electrodes that diametrically oppose one another at a position spaced from the distal tip of the sheath. The sheath includes a plurality of flexible sections spaced apart from one another, and a pull wire that causes the sheath to deflect from a straight configuration to a dual hinged curved configuration that positions the electrodes in the vicinity of the bundle of His.

Various embodiments of the present disclosure can include a deflectable catheter shaft. The deflectable catheter shaft can include a tubular elongated body including a wall, an inner surface of which circumferentially surrounds and defines a central lumen extending a length of the tubular elongated body, the tubular elongated body extending along a longitudinal axis and comprising a body distal end and a body proximal end. The deflectable catheter shaft can include a pullwire, wherein the pullwire includes a pullwire proximal end and a pullwire distal end, and wherein the pullwire extends along the tubular elongated body. The deflectable catheter shaft can include an anchor feature coupled to the pullwire distal end, wherein the anchor feature is embedded in the wall of the body distal end.
