Single-path lead for an active implantable medical device of the implantable defibrillator/cardiovertor type

Abstract

A single-path lead for an active implantable medical device of the implantable defibrillator/cardioverter type. The lead includes a lead body (10) carrying first (14) and second (16) atrial electrodes for sensing an atrial cardiac signal, first (18) and second (20) ventricular electrodes for sensing a ventricular cardiac signal, one (18) of these ventricular electrodes also being an electrode for use in the application of defibrillation or cardioversion energy (shock pulses), and a supra-ventricular electrode (12) for use in the application of the aforementioned shock energy for the defibrillation or cardioversion. An electric connection (24), preferably internal to the lead, joins together one of the atrial electrodes (14; 16) and the supra-ventricular electrode (12), the aforementioned atrial cardiac signal being collected by the lead between, on the one hand, the supra-ventricular electrode (12) and the atrial electrode (14; 16) which is connected to it and, on the second hand, the other atrial electrode (16; 14).
