  • Publication number: 20160361543
    Abstract: Feedback regarding electrical stimulation is provided to a patient. Electrical stimulation is applied to the patient. The electrical stimulation is applied by varying an electrical stimulation parameter. A signal is communicated to the patient via an electronic device. The signal is correlated with the electrical stimulation parameter such that the signal varies in association with the varying of the electrical stimulation parameter. The communicating is performed while the electrical stimulation is applied. Feedback is received from the patient in response to the electrical stimulation. Based on the received feedback from the patient, the electrical stimulation is adjusted.

  • Patent number: 9504830
    Abstract: The present disclosure involves a method of measuring a physiological feedback from a patient in response to electrical stimulation. A stimulation parameter of a sacral nerve stimulation therapy is ramped up. The sacral nerve stimulation therapy includes electrical pulses generated by a pulse generator based on programming instructions received from an electronic programmer. The electrical pulses are delivered to a patient via a stimulation lead that is implanted in the patient. Via an anal electrode device that is at least partially inserted inside an anal canal of the patient, a compound motor action potential (CMAP) is measured from an anal sphincter of the patient while the stimulation parameter of the sacral nerve stimulation therapy is being ramped up. A stimulation threshold is determined based on the measured CMAP.

  • Publication number: 20160339250
    Abstract: A medical system includes an implantable lead having a plurality of electrode contacts, a pulse generator coupled to the lead and configured to generate electrical pulses to be delivered to a patient through the plurality of electrode contacts, and an electronic programmer coupled to the pulse generator. The electronic programmer programs the pulse generator to generate the electrical pulses. The pulse generator is programmed to generate an electrical stimulation to be applied to the patient via one of the electrode contacts on the implantable lead. A determination is received as to whether the patient, in response to the electrical stimulation, exhibited a bellows response or a toes response. A stimulation parameter of the electrical stimulation is ramped up in response to a determination that the patient did not exhibit the bellows response or the toes response and that the patient did not feel pain in response to the electrical stimulation.

  • Publication number: 20160303387
    Abstract: One or more virtual objects are displayed on an electronic programmer. The virtual objects represent initiating and terminating a delivery of a medical therapy to a patient. An actuation of the one or more virtual objects is sensed. The delivery of the medical therapy is terminated immediately if the actuation of the one or more virtual objects corresponds to terminating the delivery of the medical therapy. The delivery of the medical therapy is initiated in a delayed manner if the actuation of the one or more virtual objects corresponds to starting the delivery of the medical therapy. A battery level of the electronic programmer is monitored. At least one of the following tasks is performed if the battery level is lower than a target battery level: disallowing programming of the electronic programmer; terminating the delivery of an existing medical therapy; and precluding the delivery of a prospective medical therapy.

  • Patent number: 9375574
    Abstract: A computer assisted programming method includes ramping up a stimulation current for a plurality of contacts on a lead. Patient feedback is received while the stimulation current is being ramped up. Patient feedback indicates that the patient is beginning to feel stimulation. Based on the patient feedback, amplitude of the stimulation current that resulted in the patient feedback is recorded, and contacts are divided into groups. The contacts are activated one group at a time to the recorded amplitude. For each activated group of contacts, whether the patient can feel stimulation is determined. Thereafter, the target group that caused the patient to feel stimulation is then sub-divided into sub-groups. This process repeats a plurality of cycles until one or more contacts that caused the patient to feel stimulation are identified. The recorded amplitude is assigned as a perception threshold for the identified one or more contacts.

    Abstract: A model of an implantable lead is provided via a graphical user interface. The implantable lead is configured to deliver electrical stimulation to a patient via a plurality of electrodes located on the implantable lead. The graphical user interface also provides a plurality of predefined electrode activation patterns that include a coarse pattern and a refined pattern. The coarse pattern corresponds to a first group of electrodes located in a first region of the implantable lead. The refined pattern corresponds to a second group of electrodes located in a second region of the implantable lead. The second region is smaller than, and is a subsection of, the first region. A coarse testing process is performed by selectively activating the first group of electrodes belonging to the coarse pattern. Thereafter, a refined testing process is performed by selectively activating the second group of electrodes belonging to the refined pattern.

  • Publication number: 20160022996
    Abstract: A computer-assisted stimulation programming of an implantable medical device is performed. A perception threshold is determined for a plurality of contacts on a lead configured to be implanted inside a patient. The perception threshold is determined by automatically performing a first sweep of the plurality of contacts and automatically performing a second sweep of a stimulation parameter. A paresthesia coverage provided by the plurality of contacts is determined by automatically performing a third sweep of the plurality of contacts and automatically performing a fourth sweep of the stimulation parameter. The fourth sweep is performed based on the determined perception thresholds. The first sweep, the second sweep, the third sweep, and the fourth sweep are performed without needing a manual input from a human user. A subset of the contacts corresponding to the paresthesia coverage is selected. In response to user input, stimulation programming is performed using the subset of contacts.

  • Publication number: 20150328463
    Abstract: A patient feedback device for use in an electrical stimulation system is calibrated. The electrical stimulation system includes an implantable pulse generator (IPG) implanted in a patient and a patient feedback device having a force sensor. Input from the patient is sensed using the patient feedback device. At a first time, an electrical stimulus is applied with the IPG. The force sensor is monitored at a plurality of time points. A level of force sensed by the force sensor at each of the plurality of time points is recorded. A time point at which a maximum force is applied is identified, or a time point at which a minimum force is applied is identified. The first time is compared to the time point at which a minimum force is applied or the time point at which a maximum force is applied, in order to determine a patient response time.
