Abrégé

A charging system for an Implantable Medical Device (IMD) is disclosed having a charging coil and one or more sense coils preferably housed in a charging coil assembly coupled to an electronics module by a cable. The charging coil is preferably a wire winding, while the sense coils are preferably formed in one or more traces of a circuit board. One or more voltages induced on the one or more sense coils can be used to determine one or more parameters (magnitude, phase angle, resonant frequency) indicative of the position between the charging coil and the IMD, which position may include the radial offset and possibly also the depth of the charging coil relative to the IMD. Knowing the position, the power of the magnetic field produced by the charging coil can be adjusted to compensate for the position.

Abrégé

Techniques for pairing an external device such as a clinician programmer (CP) to an implantable medical device (IMD) are disclosed, which involve use of a remote controller (RC) paired to the IMD. The RC is placed into a CP pairing mode, which acts differently depending on the type of IMD paired to the RC. If the IMD is RF based, the CP pairing mode places the IMD in a pairing mode, thus allowing the CP to connect directly with the IMD via a RF telemetry protocol. If the IMD is magnetic-induction based, the CP pairing mode causes the RC to advertise its presence to the CP, allowing the CP to connect to the RC via the RF telemetry protocol. Because the RC is also paired with the IMD via a magnetic induction telemetry protocol, the RC acts as a passthrough device to allow communications between the CP and the IMD.

Recovery circuitry for passively recovering charge from capacitances at electrodes in an Implantable Pulse Generator (IPG) is disclosed. The passive recovery circuitry includes passive recovery switches intervening between each electrode node and a common reference voltage, and each switch is in series with a variable resistance that may be selected based on differing use models of the IPG. The passive recovery switches may also be controlled in different modes. For example, in a first mode, the only recovery switches closed after a stimulation pulse are those associated with electrodes used to provide stimulation. In a second mode, all recovery switches are closed after a stimulation pulse, regardless of the electrodes used to provide stimulation. In a third mode, all recovery switches are closed continuously, which can provide protection when the IPG is in certain environments (e.g., MRI), and which can also be used during stimulation therapy itself.

Abrégé

Methods and systems for testing and treating spinal cord stimulation (SCS) patients are disclosed. Patients are eventually treated with sub-perception (paresthesia free) therapy. However, supra-perception stimulation is used during “sweet spot searching” during which active electrodes are selected for the patient. This allows sweet spot searching to occur much more quickly and without the need to wash in the various electrode combinations that are tried. After selecting electrodes using supra-perception therapy, therapy is titrated to sub-perception levels using the selected electrodes. Such sub-perception therapy has been investigated using pulses at or below 10 kHz, and it has been determined that a statistically significant correlation exists between pulse width (PW) and frequency (F) in this frequency range at which SCS patients experience significant reduction in symptoms such as back pain. Beneficially, sub-perception stimulation at such low frequencies significantly lowers power consumption in the patient's neurostimulator.

Abrégé

Sense amplifier circuits particularly useful in sensing neural responses in an Implantable Pulse Generator (IPG) are disclosed. The IPG includes a plurality of electrodes, with one selected as a sensing electrode and another selected as a reference to differentially sense the neural response in a manner that subtracts a common mode voltage (e.g., stimulation artifact) from the measurement. The circuits include a differential amplifier which receives the selected electrodes at its inputs, and comparator circuitries to assess each differential amplifier input to determine whether it is of a magnitude that is consistent with the differential amplifier's input requirements. Based on these determinations, an enable signal is generated which informs whether the output of the differential amplifier validly provides the neural response at any point in time. Further, clamping circuits are connected to the differential amplifier inputs to clamp these inputs in magnitude to prevent the differential amplifier from damage.

Stimulation parameters for the patient are determined that provide sub-perception stimulation to address a symptom of the patient. A schedule is determined to provide scheduled boluses of stimulation, where each bolus comprises a duration during which stimulation is applied to the patient in accordance with the stimulation parameters, and where the scheduled boluses are separated by off times when no stimulation is provided to the patient. Preferably, the duration of each of the scheduled boluses is 3 minutes or longer, and the duration of each of the off times is 30 minutes or greater. Additional boluses can be provided on demand in addition to the scheduled boluses by selecting an option on the external device, although the provision of such additional boluses may be constrained by a lockout period.

An architecture is disclosed for an Implantable Pulse Generator having improved compliance voltage monitoring and adjustment software and hardware. Software specifies which stimulation pulses are to be measured as relevant to monitoring and adjusting the compliance voltage. Preferably, specifying such pulses occurs by setting a compliance monitoring instruction (e.g., a bit) in the program that defines the pulse, and the compliance monitor bit instruction may be set at a memory location defining a particular pulse phase during which the compliance voltage should be monitored. When a compliance monitor instruction issues, the active electrode node voltages are monitored and compared to desired ranges to determine whether they are high or low. Compliance logic operates on these high/low signals and processes them to decide whether to issue a compliance voltage interrupt to the microcontroller, which can then command the compliance voltage generator to increase or decrease the compliance voltage.

Abrégé

A neural ablation system is disclosed, which is coupleable to two reference electrodes affixable to the skin of the patient which act as a return for current provided through a needle electrode that provides the ablation therapy. Because the reference electrodes are included in the ablation current path, they are at risk of heating if they are not well affixed. The system includes resistance monitoring circuitry for monitoring the resistance of the reference electrodes, including a measurement source which operates independently of and is isolated from the ablation source. The measurement source applies a voltage across a series connection of two capacitors. The center node between the capacitors is connected to a common reference of the ablation source. The measurement and ablation sources operate at different frequencies, such that the impedance of the capacitors are different (e.g., open or short circuited) at these frequencies, which provides the isolation.

A method for optimizing stimulation for a patient having a stimulator device such as a Deep Brain Stimulation (DBS) device is disclosed, which involves a consideration of tissue imaging information in the environment around the lead. Test stimulation is provided at initial combinations of lead positions and values of a stimulation parameter such as amplitude, with patient results scored for each combination. Tissue imaging information is assessed in conjunction with these scores, and a next combination of position and a value of the stimulation parameter to test is determined. This process repeats iteratively until a stopping criterium is met. The lead positions in question may be longitudinal or rotational positions around the lead, and preferably both if the lead is directional in nature. Tissue imaging information can also be used to exclude certain positions or stimulation values during subsequent optimization testing.
