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 end face, and the mapping electrodes may include two electrodes that diametrically oppose one another at a position exposed on or spaced from the distal end face. 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 substantially straight configuration to a dual hinged curved configuration that maneuvers and positions the electrodes in the vicinity of the bundle of His. The sheath may include a PTFE liner having axially oriented, platelet-like fibril features that enable the sheath to be split along its length from a proximal end to the distal end.
