An active implantable medical device including, once implanted, a module external to the patient and a module inside the patient, the external module and the internal module being intended to transfer energy and data from one to the other. Also, a method for transferring energy and data, the method being implemented by the active implantable medical device.

Active implantable medical device

A device includes a pulse generator coupled to a neurostimulation lead placed around the nerve and a set of electrodes individually connected to the generator by a splitter circuit controlled to preferentially stimulate certain regions of the nerve relative to other regions. The device performing an iterative search of an optimal configuration operating by selection of a plurality of different stimulation configurations, storing of a cardiac physiological parameter measured for each selected stimulation configuration, and designation as optimal stimulation configuration of the one of said selected different stimulation configurations, depending on at least the stored values of the physiological parameter measured for different electrode configurations.

A control device implantable in a human body&#x2014;includes a control unit and at least one electrode, said control unit being connected to each electrode to control stimulation and/or measurement thereof. The control unit includes: a timing dock; a memory storing configuration data defined to enable configuration of each electrode correlated with identifiers; a memory storing program data describing a time profile correlated with identifiers; an executor activatable to send each electrode electric pulses corresponding to a predetermined program according to a predetermined electrode configuration, according to the clock; a sequencer arranged to receive an ordered plurality of pairs, each including an electrode configuration identifier and a program identifier, and selectively to activate the executor with the electrode and program configuration pairs denoted by the pairs of identifiers received as an input, according to the order thereof and the clock.

Control device for selective activation of electrode configuration

A device (ES) for distributing power between n cathodes (Ki) of at least one multipolar stimulating electrode (EM) comprises at least one anode (A), wherein n is equal to or greater than two. Said device (ES) comprises a reconfigurable current mirror (MC) which is provided with n outputs (K'i) connectable to said n cathodes (Ki), respectively and supplies to the n (K&#x2032;i) outputs n complementary fractions of a control current having respective selected values which are substantially constant at the control current amplitude variation in order to carry out a substantially constant spatial location of stimulation.
