  • Publication number: 20160030741
    Abstract: Techniques for managing urinary or fecal incontinence include delivering a first type of therapy to generate a first physiological response and, upon detecting a trigger event, delivering a second type of therapy to generate a second physiological response. The first type of therapy can be delivered on a substantially regular basis, while the second type of therapy is delivered as needed to provide an additional boost of therapy. The trigger event for activating the delivery of the second type of therapy may include input from a sensor that indicates a bladder condition, patient activity level or patient posture, or patient input. In some examples, the therapy is stimulation therapy.

  • Publication number: 20150087896
    Abstract: A urinary tract valve includes an expandable valve element positionable within a bladder of a patient via a urinary tract of the patient in a collapsed configuration. The expandable valve element is configured to transition from the collapsed configuration to an expanded configuration after being positioned within the bladder of the patient. The expandable valve element includes a ferromagnetic element that facilitates selective control of the expandable valve element with a magnetic field between an open position and a closed position when positioned within the bladder of the patient. In the closed position, the expandable valve element is configured to seal an internal urethral opening of the patient. In the open position, the expandable valve element is configured to allow urine to pass from the bladder of the patient, through an internal urethral opening of the patient and into a urethra of the patient.

  • 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.

  • Publication number: 20140163580
    Abstract: A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

  • Publication number: 20140163579
    Abstract: A medical device system for delivering a neuromodulation therapy includes a delivery tool for deploying an implantable medical device at a neuromodulation therapy site. The implantable medical device includes a housing, an electronic circuit within the housing, and an electrical lead comprising a lead body extending between a proximal end coupled to the housing and a distal end extending away from the housing and at least one electrode carried by the lead body. The delivery tool includes a first cavity for receiving the housing and a second cavity for receiving the lead. The first cavity and the second cavity are in direct communication for receiving and deploying the housing and the lead coupled to the housing concomitantly as a single unit.

  • Publication number: 20140163644
    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.

  • Patent number: 8712534
    Abstract: In some examples, the disclosure relates to system, devices, and techniques for delivering electrical stimulation therapy to treat patient disorders characterized by overactive nerve activity. In one example, the stimulation therapy may include high frequency and low frequency stimulation. The high frequency stimulation may be configured to substantially block overactive pathological nerve activity of the patient and the combination of the high frequency and low frequency simulation may be configured to result in nerve activity that mimics non-pathological nerve activity.

  • Publication number: 20140058292
    Abstract: A system for use in managing a neuromodulation therapy includes an ultrasound transducer array controlled by a control unit to deliver ultrasound waveforms for causing modulation of neural tissue in a patient. The system acquires data indicating a response to the modulation, analyzes the acquired data to determine correlation data between a response to the modulation and an ultrasound control parameter, and reports the correlation data to enable identification of at least one therapy parameter to be used to deliver a neuromodulation therapy to the patient by a therapy delivery system.

  • Publication number: 20120010680
    Abstract: In general, the disclosure describes techniques for providing conditional electrical stimulation to a patient for pelvic health. An implantable medical device (IMD) may adjust the delivery cycle of the electrical stimulation applied to a patient in response to receiving a delivery cycle parameter associated with one or more of the following: a time in a time schedule, a control device output from a control device, and physiological information from a physiological information sensing device. As an example, the IMD may monitor a status of one or more inputs of the IMD and adjust the delivery cycle of the electrical stimulation applied to the patient based on the status of the input(s).
