  • Publication number: 20190038902
    Abstract: A medical device may receive sensor data from sensing sources, and determine confidence levels for sensor data received from each of the plurality of sensing sources. Each of the confidence levels of the sensor data from each of the sensing sources is a measure of accuracy of the sensor data received from respective sensing sources. The medical device may also determine one or more therapy parameter values based on the determined confidence levels, and cause delivery of therapy based on the determined one or more therapy parameter values.

  • Patent number: 10045764
    Abstract: An external medical device generates a drive signal inductively coupled to an implantable coil from an external coil. A regulator module coupled to the implantable coil generates an output signal in response to the inductively coupled signal and a feedback signal correlated to an amplitude of the inductively coupled signal. A signal generator receives the output signal for generating a therapeutic electrical stimulation signal. The control module adjusts the drive signal in response to the feedback signal to control the electrical stimulation signal.

  • Publication number: 20180085572
    Abstract: Techniques are disclosed for defining a homeostatic window for controlling delivery of electrical stimulation therapy to a patient. In one example, a method includes generating and delivering electrical stimulation therapy to tissue of a patient via electrodes. Further, the method includes adjusting a level of a parameter of the electrical stimulation therapy such that a signal of the patient is not less than a lower bound and not greater than an upper bound. The lower bound is determined to be the magnitude of the signal while receiving electrical stimulation therapy sufficient to reduce one or more symptoms of a disease while the patient was receiving medication for reduction of the one or more symptoms. Further, the upper bound is determined to be the magnitude of the signal while receiving electrical stimulation therapy sufficient to reduce the one or more symptoms when the patient was not receiving the medication.

  • Patent number: 9919159
    Abstract: A programming session for an implantable medical device that includes a posture responsive therapy mode includes at least two phases. In a first phase, a first set of therapy parameter values are modified while the posture responsive therapy mode is deactivated. In the posture responsive therapy mode, the medical device automatically selects one or more therapy parameter values that define therapy delivered to a patient based on a detected posture state. In a second phase, the posture responsive therapy mode is activated and a second set of therapy parameter values are adjusted after observing a patient response to the posture responsive therapy delivered with the first set of therapy parameter values selected during the first phase. The second set of therapy parameter values may, for example, define the patient posture states or the modification profiles with which the medical device adjusts therapy upon detecting a posture state transition.

  • Patent number: 9185087
    Abstract: Devices, systems, and techniques for generating an encryption key using detected motion from a device. In one example, a method may include receiving movement information indicative of motion detected by a first device during a period of time in which the first device and a second device were bumped together, determining a set of values that represent at least one characteristic of the movement information, and generating, based on the set of values, an encryption key for at least one of encrypting and decrypting data communicated between the first device and the second device. In some examples, the first device may include a sensor configured to detect each time the first device is bumped with the second device during the period of time. The first and second devices may be an implantable medical device and a programmer for the implantable medical device.

  • Patent number: 8903486
    Abstract: Techniques for detecting a value of a sensed patient parameter, and automatically delivering therapy to a patient according to therapy information previously associated with the detected value, are described. In exemplary embodiments, a medical device receives a therapy adjustment from the patient. In response to the adjustment, the medical device associates a sensed value of a patient parameter with therapy information determined based on the adjustment. Whenever the parameter value is subsequently detected, the medical device delivers therapy according to the associated therapy information. In this manner, the medical device may “learn” to automatically adjust therapy in the manner desired by the patient as the sensed parameter of the patient changes. Exemplary patient parameters that may be sensed for performance of the described techniques include posture, activity, heart rate, electromyography (EMG), an electroencephalogram (EEG), an electrocardiogram (ECG), temperature, respiration rate, and pH.

  • Publication number: 20140180870
    Abstract: An authorization is required for performance of medical tasks by an implantable medical device (IMD). The authorization may be based on a process implemented by the IMD to check for the authorization. As an alternative, the authorization may be based on a process implemented by an external device, such as to check whether there is authorization to provide a power transmission to the implantable medical device that is necessary for the IMD to perform the medical task. This authorization allows a fee to be charged to performance of the medical task, which in turn allows the initial cost of the IMD to be substantially reduced. This in turn increases the population of patients that are able to afford the IMD to improve their quality of life, which increases the number of IMDs that can ultimately be sold.

  • Patent number: 8444578
    Abstract: A wearable ambulatory data recorder that senses physiological parameters of a patient, and stores physiological parameter data for later retrieval, as well as techniques for using such a wearable ambulatory data recorder, are described. The data recorder includes one or more sensors located on or within a housing. The data recorder may include an adhesive layer for attachment to a patient. In some embodiments, the housing may be within a patch, e.g., bandage, which includes the adhesive layer. The housing may be waterproof. Features of the data recorder such as size, waterproofness, and inclusion of an adhesive may allow the data recorder to be unobtrusively worn by a patient during a variety of daily activities. The data recorder may be for single use and thereafter disposable.

  • Publication number: 20130110008
    Abstract: In general, the techniques of this disclosure are directed to communication between an implantable medical device (IMD) and an external device. In some examples, the external device transmits a signal that includes a communication key. One or more sensors of the IMD sense the signal that includes the communication key, and the IMD uses the communication key for coding the communication between the IMD and the external device. The one or more sensors that sensed the signal may also sense one or more patient characteristics.

  • Publication number: 20120197356
    Abstract: Electrical stimulation systems and methods are configured to deliver remote electrical stimulation to a patient. Stimulation waveforms are employed that are designed to penetrate tissue within a patient to transmit the electrical stimulation from an origination site to a remote delivery site. The waveforms are defined by a series of pulses, which are characterized by a number of parameters, including pulse width, pulse frequency, constant voltage or constant current amplitude, and electrode polarity (anode or cathode). The waveforms include an envelope electrical stimulation pulse train including charge balanced pulses modulated by a high frequency carrier signal configured to deeply penetrate patient tissue to carry the electrical pulse train from an origination site to a remote delivery site.

  • Patent number: 7776031
    Abstract: An implantable drug infusion pump for delivering drug therapy to a patient and which also permits a patient to deliver or self-administer an additional bolus, reduces the likelihood of over dosage or under dosage by drug dosage characteristic limitations programmed into a microprocessor memory. The dose limits define the maximum and minimum amount of drug to be delivered per unit time or otherwise, reducing the likelihood that a patient may inadvertently or deliberately interfere with a treatment regimen.
