  • Patent number: 9008778
    Abstract: An implantable control module for an electrical stimulation system includes a header coupled a sealed body. The header includes at least one connector assembly. The control module also includes a conductive shield disposed over at least a portion of the connector assembly or connector assemblies of the header. The conductive shield is provided to hinder generation of current in the header or in a portion of a lead received in the header in response to application of an external radiofrequency (RF) or magnetic field. A similar shield can also be used to shield a connector assembly disposed on the end of a lead extension or any other component of the electrical stimulation system.

  • Patent number: 8994325
    Abstract: Improved external chargers for charging an implantable medical device, and particularly useful in charging a plurality of such devices, are disclosed. Each of the various embodiments include design elements for mechanically manipulating the position of one or more charging coils within the external charger to customize the magnetic charging field as appropriate for the charger/implantable device environment. For example, a single charging coil may be moved within a housing of the external charger to direct the charging field of the coil towards the currently “coldest” implant, i.e., the implant with the lowest coupling to the external charger. The one or more charging coils may be mechanically manipulated within the external charger housing in a number of ways, including by using linear actuators, by inflatable bladders, or even by hand.

  • Patent number: 8965524
    Abstract: Disclosed is a remote controller for an implantable medical device having stored contraindication information, which includes information which a patient or clinician might wish to review when assessing the compatibility of a given therapeutic or diagnostic technique or activity with the patient's implant. The stored contraindication information is available through a display of the remote controller or via a wired, wireless, or portable drive connection with an external device. By storing contraindication information with the implant's remote controller, patient and clinician can more easily determine the safety of a particular therapeutic or diagnostic technique or physical activity with the patient's implant, perhaps without the need to contact the manufacturer's service representative.

  • Publication number: 20140336726
    Abstract: A method for configuring stimulation pulses in an implantable stimulator device having a plurality of electrodes is disclosed, which method is particularly useful in adjusting the electrodes by current steering during initialization of the device. In one aspect, a set of ideal pulses for patient therapy is determined, in which at least two of the ideal pulses are of the same polarity and are intended to be simultaneous applied to corresponding electrodes on the implantable stimulator device during an initial duration. These pulses are reconstructed into fractionalized pulses, each comprised of pulse portions. The fractionalized pulses are applied to the corresponding electrodes on the device during a final duration, but the pulse portions of the fractionalized pulses are not simultaneously applied during the final duration.

  • Publication number: 20140277287
    Abstract: An external charger for a battery in an implantable medical device and charging techniques are disclosed. Simulation data is used to model the power dissipation of the charging circuitry in the implant at varying levels of implant power. A power dissipation limit constrains the charging circuitry from producing an inordinate amount of heat to the tissue surrounding the implant, and duty cycles of a charging field are determined so as not to exceed that limit. A maximum simulated average battery current determines the optimal (i.e., quickest) battery charging current, and at least an optimal value for a parameter indicative of that current is determined and stored in the external charger. During charging, the actual value for that parameter is determined, and the intensity and/or duty cycle of the charging field are adjusted to ensure that charging is as fast as possible, while still not exceeding the power dissipation limit.

  • Publication number: 20140277267
    Abstract: An external control device and method for programming an implantable neuromodulator coupled to an electrode array implanted adjacent tissue of a patient having a medical condition. Electrical modulation energy is conveyed to tissue of the patient in accordance with a series of modulation parameter sets. The patient perceives paresthesia in response to the conveyance of the electrical modulation energy to the tissue in accordance with at least one of the modulation parameter sets. One of the modulation parameter set(s) is identified based on the perceived paresthesia. Another modulation parameter set is derived from the identified modulation parameter set. Electrical modulation energy is conveyed to the tissue of the patient in accordance with the other modulation parameter set without causing the patient to perceive paresthesia.

  • Publication number: 20140228912
    Abstract: An example of a method performed by an implantable medical device (IMD) to deliver a therapy to a patient may include delivering the therapy to the patient, detecting a trigger that is controlled by the patient or a caregiver to the patient, and determining if at least one feature of the IMD for responding to a trigger is enabled. The IMD may be configured to allow the patient or the caregiver to the patient to enable the at least one feature. The method may further include, when the at least one feature is enabled, automatically implementing the at least one enabled feature in response to the detected trigger, including automatically suspending the therapy in response to the detected trigger and automatically restoring the therapy after a defined period after the detected trigger.

  • Publication number: 20140200631
    Abstract: An external charger for a battery in an implantable medical device (implant), and technique for charging batteries in multiple implants using such improved external charger, is disclosed. During charging, values for a parameter measured in the implants are reported from the implants to the external charger. The external charger infers from the magnitudes of the parameters which of the implants has the highest (hot) and lowest (cold) coupling to the external charger. The intensity of the magnetic charging field is optimized for the cold implant to ensure that it is charged with a maximum (fastest) battery charging current. The duty cycle of the magnetic charging field is also optimized for the hot implant to ensure that it does not exceed a power dissipation limit. As a result, charging is optimized to be fast for all of the implants, while still safe from a tissue heating perspective.
