A medical lead is provided for use in a pulse stimulation system of the type which includes a pulse generator for producing electrical stimulation therapy. The lead comprises an elongate insulating body and at least one electrical conductor within the insulating body. The conductor has a proximal end configured to be electrically coupled to the pulse generator and has a DC resistance in the range of 375-2000 ohms. At least one distal electrode is coupled to the conductor.

MRI-safe implantable medical device

A medical device detects a previously defined event, and controls delivery of therapy to a patient according to therapy information associated with the previously defined event. In exemplary embodiments, the medical device enters a learning mode in response to a command received from a user, e.g., the patient or a clinician. In such embodiments, the medical device defines the event, collects the therapy information, and associates the therapy information with the defined event while operating in the learning mode. In some embodiments, the medical device defines the event based on the output of a sensor that indicates a physiological parameter of the patient during the learning mode. The sensor may be an accelerometer, which generates an output that reflects motion and/or posture of the patient. The medical device may collect therapy information by recording therapy changes made by the user during the learning mode.

A medical lead is provided for use in a pulse stimulation system of the type which includes a pulse generator for producing electrical stimulation therapy. The lead comprises an elongate insulating body and at least one electrical conductor within the insulating body. The conductor has a proximal end configured to he electrically coupled to the pulse generator and has a DC resistance in the range of 375-2000 ohms. At least one distal electrode is coupled to the conductor.

A modular implantable medical device (IMD) may include a non-hermetic interconnect. The non-hermetic interconnect may electrically couple a first module and a second module of the modular IMD. A conductor in the non-hermetic interconnect may conduct electrical energy from the first module to the second module under an applied direct current (DC) voltage.

An implantable medical device with lubricious material permits implantable medical devices to have a reduced friction between the device and at least a portion of the surrounding tissue. The implantable medical device may have a housing or it may have a housing and a member for providing a smooth interface between the device and the tissue. The lubricious material may be provided on or impregnated in the housing or the member. In some embodiments, the device is configured for implantation in the head of a human body. In other embodiments, the device is configured for implantation between the cranium and the scalp. In some embodiments, the device includes a single module while in other embodiments a plurality of modules are coupled together to provide a smaller profile.

The disclosure describes an implantable neurostimulator device for delivery of neurostimulation to treat head, neck, or facial pain or tension, including pain or tension caused by occipital neuralgia. The device may be a neurostimulation device having a miniaturized housing with a low profile that permits subcutaneous implantation at a stimulation site directly adjacent a neuralgic region at the back of the neck of a patient. For example, the device may be subcutaneously implanted at the back of the neck of a patient to relieve symptoms of occipital neuralgia.

Implantable medical devices (IMDS) having anti-infective properties are described. Anti-infective agents are disposed in, on, or about at least a portion of a surface of the medical device. The anti-infective agents are disposed in or on a vehicle, which may be in the form of a coating layer or covering. The vehicle may be biodegradable so that, over time, the anti-infective agent is removed from a tissue location into which the device is implanted, reducing the likelihood that microorganisms resistant to the anti-infective agent will develop. IMDs having an anti-infective agent and an anti-activity agent disposed therein, thereabout, or thereon are also described. The anti-activity agent interferes with the activity of the anti-infective agent, may be released from a surface at the IMD at a time when activity of the anti-infective agent is no longer desired, and may reduce the likelihood that microorganisms resistant to the anti-infective agent will develop.

Anti-infective medical device

In an implantable medical device having individual modules, a coupling module couples the modules to one another. The coupling module supports electrical and/or mechanical coupling of the modules. The coupling module may assume a variety of shapes or configurations. The various embodiments of the coupling module may offer the modules varying degrees of freedom of movement relative to one another.
