Title: Configurable multisite active implantable medical device

Abstract: An active implantable medical device, especially a cardiac pacemaker, defibrillator and/or cardiovertor, of the configurable multisite type. In this multisite device, electrodes are placed in at least three distinct myocardial sites for stimulation (12, 14, 20, 22), of which at least one is a site for ventricular stimulation/detection (14, 22), these electrodes being connected to independent outputs (DA, DV, Da1, Dv2) of the multisite device in a manner as to allow the application of stimulation pulses produced by a plurality of distinct stimulation stages (24, 26, 28, 30). The number of stimulation output stages is at most equal to the number of stimulation sites. The device also includes switches (SA, SV, S1, S2) to connect selectively and according to one of various possible stimulation configurations, the stimulation stages, or selected ones of the stimulation stages, to the various sites of stimulation, or to selected ones of the stimulation sites. The switches can be controlled to modify the stimulation configuration as between the various possibilities in a manner as to research (to identify) the one considered as optimal among the possible variations, which can then be selected.
