Abstract

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.
