Abstract
A medical electrical lead system having a torque transfer stylet. In a preferred embodiment, the torque transfer stylet comprises an elongated, stylet wire having proximal, intermediate and distal sections. The proximal and distal section of the stylet wire have a first diameter. The intermediate section spans between the proximal and distal sections. The stylet wire in this region, however, has a second diameter, the second diameter smaller than the first diameter of the proximal and distal sections. In addition, the intermediate section further has a length of torque coil wrapped thereabout. The torque coil preferably is wound in a coiled diameter which is the same as the first diameter of the proximal and distal sections of the stylet wire. Through such a configuration the stylet has an overall nearly uniformed diameter through its length.
