This enables closed-loop therapy in the sub-perception domain where ECAP features are not visually detectable. A clinician programmer applies the model and sub-perception dose to therapy programs deployed to the IPG. The model can be customized to each patient by collecting ECAP and accelerometer data. The mapping reconciles ECAP-based control between perception and sub-perception domains by supplementing unavailable ECAP data with accelerometer data. This improves stimulation therapies for patients receiving sub-perception and multi-sensor paresthesia treatments.

A fitting algorithm for a spinal cord stimulator is disclosed, which is preferably implemented in a clinician programmer having a graphical user interface. In one example, coupling parameters indicative of coupling to neural structures are determined for each electrode in an implanted electrode array. The user interface associates different pole configurations with different anatomical targets and with different measurement techniques (subjective or objective) to gauge the effectiveness of the pole configuration at different positions in the electrode array. The pole configuration, perhaps as modified by the coupling parameters, is then steered in the array, and effectiveness is measured along with a paresthesia threshold at each position. Using at least this data, the fitting algorithm can determine one or more candidate positions in the electrode array at which a therapeutic stimulation program can be centered.

Abrégé

A programming algorithm is disclosed to efficiently select stimulation parameters for a patient having a Deep Brain Stimulation (DBS) implant. The algorithm preferably first determines an optimal longitudinal position (Lopt) and amplitude (Iopt1) for stimulation along the lead. This occurs by the algorithm efficiently suggested various values for L and I at which stimulation can be tried on the patient and scored. Once Lopt is determined, the algorithm can also determine an optimal rotational angle (θopt) and amplitude (Iopt2) for stimulation around the lead at the optimized longitudinal position Lopt. This also occurs by the algorithm efficiently suggesting various values for θ and I at which stimulation can be tried on the patient and scored. Despite suggesting next L,I or θ,I values to test, the algorithm allows flexibility to allow a user to test any desired stimulation parameters beyond those suggested.

Abrégé

Implantable medical devices (IMD) such as those used in Deep Brain Stimulation application are commonly replaced when the device's useful life expires. At the time of replacement, the electrodes that were connected to the initial IMD are typically reused with the replacement IMD. It is desirable for the replacement IMD to utilize the stimulation parameters that were being utilized to provide stimulation in the initial IMD, but it is important that the electrodes be connected to the replacement IMD in a similar manner as they were connected to the initial IMD if stimulation parameters are reused. A connected electrode profile that includes measurements of electrical parameters associated with the electrodes can be generated in the initial IMD and the replacement IMD, and the profiles can be compared to determine whether the electrodes are connected in a similar manner in the replacement IMD as they were in the initial IMD.

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.

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. One or more objective criteria are measured and scored. The objective criteria may be electrode impedances and/or indicators of stress, such as cardiac signals. 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.

A filtering algorithm implemented by a filtering module in an implantable medical device (IMD), or in an external device for communicating with an IMD, is disclosed which reviews blocks based on a number of rules. The filtering module preferably comprises both firewall and instruction analysis modules. The instruction analysis module analyzes the instructions and associated data (if present) in each block to determine whether such blocks would compromise operation of the IPG or injure a patient if executed. Instruction rules corresponding to an instruction identified in the block are retrieved by the instruction analysis module. The instruction analysis module reviews the block per the retrieved rules, and possibly also in light of current and historical IPG therapy setting or mode data, or other received but un-executed blocks. If a block is compliant, it is executed by the IMD or transmitted to the IMD.
