摘要： An active implantable medical device with a sophisticated management of the refractory periods. Such devices typically include a detection circuit and a stimulation circuit and a circuit which applies a refractory period to the detection circuit, including an absolute refractory period (ARP), which can be fixed or pre-programmed, and a relative refractory period (RRP), which is variable. The relative refractory period includes a succession of elementary periods (X) of a fixed or programmable duration, which elementary period is further subdivided into sub-periods (Y) such that an elementary period X is retriggered or restarted at the end of a sub-period Y if a residual potential of a level higher than a given threshold is detected at output of the detection circuit during that sub-period. In the absence of a detected residual potential being detected during the successive sub-periods comprising the elementary period, then the refractory period ends.

摘要： An active implantable medical device, notably a cardiac pacemaker or fibrillator, which detects the instantaneous cardiac rhythm, spontaneous or stimulated, of the bearer of the device, and delivers stimulation pulses with a variable escape interval and which increases gradually this escape interval. The gradual increase of the escape interval is obtained by memorizing information corresponding to the evolution of the cardiac rhythm sensed by a conventional detection circuit over a first time period, wherein the escape interval to be adjusted is later in time to the memorized information, notably by determining a variable rate of increase of the escape interval, which variable rate is essentially determined as a function of the memorized information, and/or by operating an integration of the previously detected cardiac rhythm.

摘要： A rate-adaptive implantable cardiac pacemaker having a control parameter representative of the physical activity of the patient. The change of the stimulation frequency follows, in a manner to reproduce the natural change of the physiological cardiac rhythm, a non-linear mathematical function of time, e.g., of the type:Fc(t)=A*(1-B*e.sup.-t/Tau)+C,in which t is time, A, B, C and Tau are constants, and Fc(t) is the stimulation frequency as a function of time. Tau may be a different value for increasing and decreasing frequencies.

摘要： 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.

摘要： An implantable cardiac device that detects and protects against strong magnetic fields produced by MRI equipment is disclosed. The device has a magnetic field sensor for detecting the presence of a relatively weak static magnetic field (102, 110, 118, 122) of a level equivalent to that of a permanent magnet in the vicinity of the device. The device is switched from a standard operating mode (100) where the nominal functions of the device are active, to a specific protected MRI mode (114, 116) in the presence of a magnetic static field of a level corresponding to that emitted by MRI equipment. The device further temporarily switches the device from the standard operating mode (100) to an MRI stand-by state (108) when a magnetic field is detected by the magnetic field sensor such that a subsequent detection of a magnetic field switches the device from an MRI stand-by state to the specific protected MRI mode.

摘要： A generator for an implantable cardiac prosthesis, having a safekeeping mode of operation during an exposure to a magnetic field. The generator is connected to a lead including a first conductor (18) connected to a distal electrode (14), and a second conductor (20) connected to a proximal electrode (16). The generator to which the lead is connected includes a switch that temporarily switches to the potential of the metal housing of the generator (i.e., the ground potential) a first terminal connection (26) coupled to the external conductor (20) of the lead, and connects to the electronic circuit of detection/stimulation a second terminal connection (24) coupled to the internal conductor (18) of the lead. The first conductor temporarily acts as a shield for the second conductor for the duration of an MRI examination ensuring protection against the deleterious effects of exposure of the lead to the magnetic field generated by the MRI apparatus, notably heating of the electrodes due to induced currents in the conductors.

This process includes the steps of producing a stimulation pulse by the discharge on the lead (10) of a tank-capacitor (22) of the device (20), charged beforehand to a given voltage level; measuring the voltage variation (V(t)) at the terminals of the tank-capacitor during the discharge; and determining the lead impedance (Zs) from the voltage thus measured. The measurement stage includes sampling at least three successive values of the voltage at the terminals of the tank capacitor, and the determining stage includes the separate determination of the resistive (Rs) and/or capacitive (CH) components of the complex impedance of the lead from the aforesaid at least three sampled values of voltage thus obtained.

摘要： An active medical device including protected registers for containing digital adjustment parameter values used for the functioning of functional modules of the device. This device includes at least one module (12) for achieving a predetermined device function, this module including a circuit specific for performing the function and which has an adjustable parameter value in the form of a digital word of N bits. Each such module includes a plurality of volatile storage registers having N bits storing the aforementioned digital words, and circuits for comparing (32, 36), the respective contents of the registers and producing an anomaly signal (IT1, IT2 . . . ITi . . . ITk) in the event of a discordance between the contents of the plurality of registers for a given module. The anomaly signal may be an interrupt signal applied to a microcontroller (10). The module also includes a majority circuit (30) receiving at its input the contents of the registers and delivering at its output to the specific circuit (24) the resulting value as the adjustment parameter value to be used in performing the function. It also is contemplated to restore the contents of corrupted registers in the event of a discordance detected by the comparison.
