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.

Minimally invasive implantable neurostimulation system

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.

An implantable medical device (IMD) has a housing enclosing an electronic circuit. The housing includes a first housing portion, a second housing portion and a joint coupling the first housing portion to the second housing portion. A polymer seal is positioned in the joint in various embodiments. Other embodiments of an IMD housing are disclosed.

A lead connector assembly includes a lead receptacle, a sleeve, and a handle for coupling to a medical lead. The lead receptacle has an inner surface and an opening configured to receive the lead. The sleeve is deflectable by the inner surface of the lead receptacle. The sleeve has a distal end portion defining a first outer diameter to engage the lead in a locked position and a second outer diameter greater than the first diameter in an unlocked position. The handle is coupled to the lead receptacle and a proximal end portion of the sleeve to move the sleeve axially in both directions along the longitudinal axis relative to the lead receptacle. The lead connector assembly retains the lead in the locked position. The lead receptacle is couplable to a medical device housing.

Toolless lead connector assembly

In some examples, a medical device system includes a first implantable medical device. The first implantable medical device (IMD) may comprise circuitry configured to at least one of deliver a therapy to a patient or sense a physiological signal from the patient; generate stimulation deliverable to a patient; a first rechargeable power source; and a secondary coil coupled to the first rechargeable power source, the secondary coil configured to charge the first rechargeable power source via inductive coupling with a primary coil of an external charging device. The medical device system may comprise processing circuitry configured to control charging of the first rechargeable power source based on a charge state of a second rechargeable power source of a second IMD.

Recharging power sources of implantable medical devices

Devices, systems, and techniques for monitoring the temperature of a device used to charge a rechargeable power source are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. The temperature of an external charging device and/or an implantable medical device may be monitored to control the temperature exposure to patient tissue. In one example, a temperature sensor may sense a temperature of a portion of a device, wherein the portion is non-thermally coupled to the temperature sensor. A processor may then control charging of the rechargeable power source based on the sensed temperature.

Sensing temperature within medical devices

In some examples, an implantable medical device (IMD) including a hermetically sealed housing that is configured to enclose internal components. The internal components may include stimulation circuitry, processing circuitry configured to control the stimulation circuitry to deliver electrical stimulation using one or more leads received by the housing, telemetry circuitry, and a rechargeable power source. The IMD may also include a coil configured to at least one of receive energy to recharge the rechargeable power source or receive and/or transmit signals for wireless telemetry with another device, wherein the implantable medical device is configured to mount to a cranium of a patient, and wherein the coil is coiled about an axis that is approximately orthogonal to a major surface of the IMD.

Implantable medical device structures including recharge and/or telemetry coil

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.

Ultrasound diagnostic and therapy management system and associated method

In some examples, an implantable medical device includes an implantable housing, a neurostimulator within the housing, a plurality of electrodes, an implantable lead coupled to the housing, and an actuator formed with the housing. The implantable lead includes at least one electrode of the plurality of electrodes and one or more conductors coupling the at least one electrode to the neurostimulator. The actuator is configured to cause at least a portion of the implantable lead to deflect.

Implantable electrical stimulator with deflecting tip lead

An implantable medical device (IMD) includes a housing that is configured to enclose internal components including at least a processor and a power source. The housing defines two major surfaces that are generally parallel to each other and one or more channels that are each configured to receive a lead and electrically couple the respective lead to the internal components, where each of the channels extend substantially straight in to the housing along an axis generally parallel to the two major surfaces. The housing may be configured to be mounted to a cranium of a patient such that at least one of the two major surfaces approximates a curvature of the cranium. The IMD may include one or more funneling walls that define a rounded and smooth transition from a sidewall of the housing to a surface that defines one or more mouths to the channels.
