Peripheral nerve field stimulation (PNFS) may be controlled based on detected physiological effects of the PNFS, which may be an efferent response to the PNFS. In some examples, a closed-loop therapy system may include a sensing module that senses a physiological parameter of the patient, which may be indicative of the patient's response to the PNFS. Based on a signal generated by the sensing module, the PNFS may be activated, deactivated or modified. Example physiological parameters of the patient include heart rate, respiratory rate, electrodermal activity, muscle activity, blood flow rate, sweat gland activity, pilomotor reflex, or thermal activity of the patient's body. In some examples, a patient pain state may be detected based on a signal generated by the sensing module, and therapy may be controlled based on the detection of the pain state.

Peripheral nerve field stimulation control

Delivery of peripheral nerve field stimulation (PNFS) in combination with one or more other therapies is described. The other therapy delivered in combination with PNFS may be, for example, a different type of neurostimulation, such as spinal cord stimulation (SCS), or a drug. PNFS and the other therapy may be delivered simultaneously, in an alternating fashion, according to a schedule, and/or selectively, e.g., in response to a request received from a patient or clinician. A combination therapy that includes PNFS may be able to more completely address complex or multifocal pain than would be possible through delivery of either PNFS or other therapies alone. Further, the combination of PNFS with one or more other therapies may reduce the likelihood that neural accommodation will impair the perceived effectiveness PNFS or the other therapies.

Combination therapy including peripheral nerve field stimulation

A device determines values for one or more metrics that indicate the quality of a patient's sleep based on sensed physiological parameter values. Sleep efficiency, sleep latency, and time spent in deeper sleep states are example sleep quality metrics for which values may be determined. The sleep quality metric values may be used, for example, to evaluate the effectiveness of a therapy delivered to the patient by a medical device. In some embodiments, determined sleep quality metric values are automatically associated with the therapy parameter sets according to which the medical device delivered the therapy when the physiological parameter values were sensed, and used to evaluate the effectiveness of the various therapy parameter sets. The medical device may deliver the therapy to treat a non-respiratory neurological disorder, such as epilepsy, a movement disorder, or a psychological disorder. The therapy may be, for example, deep brain stimulation (DBS) therapy.

Determination of sleep quality for neurological disorders

An implantable electrode paddle is adapted to receive an electrical signal from a medical device and generate an electrical field to stimulate selected body tissue. The paddle includes a housing including walls that define an interior space and a plurality of windows formed through at least a first one of the walls for transmitting the electrical field to the body tissue, an electrode array including a plurality of electrode groups, each electrode group including at least two electrodes individually secured in a respective window and spaced between about 0.1 mm and about 10 mm apart, and a plurality of wires, each of the wires being coupled to a respective electrode and routed within the interior space to receive the electrical signal. A lead assembly and an implantable medical device can include the paddle.

Field steerable electrical stimulation paddle, lead system, and medical device incorporating the same

A medical device delivers a therapy to a patient. The medical device or another device may periodically determine an activity level or gait parameter of the patient, and associate each determined level or parameter with a current therapy parameter set. A value of at least one activity metric is determined for each of a plurality of therapy parameter sets based on the activity levels or parameters associated with that therapy parameter set. Whether the patient is currently experiencing or anticipated to experience gait freeze caused by their neurological disorder, such as Parkinson's disease, may also be determined. Gait freeze events may be associated with current therapy parameters and used to determine activity metric values. In some examples, the activity metric associated with certain therapy parameters may be presented to a user.

Collecting gait information for evaluation and control of therapy

At least one of a medical device, such as an implantable medical device, and a programming device determines values for one or more metrics that indicate the quality of a patient's sleep. Sleep efficiency, sleep latency, and time spent in deeper sleep states are example sleep quality metrics for which values may be determined. In some embodiments, determined sleep quality metric values are associated with a current therapy parameter set. In some embodiments, a programming device presents sleep quality information to a user based on determined sleep quality metric values. A clinician, for example, may use the sleep quality information presented by the programming device to evaluate the effectiveness of therapy delivered to the patient by the medical device, to adjust the therapy delivered by the medical device, or to prescribe a therapy not delivered by the medical device in order to improve the quality of the patient's sleep.

Collecting sleep quality information via a medical device

A catheter body includes an exit port over which a pressure responsive sleeve is formed that allows material to exit a lumen of the catheter body at a given pressure. In one embodiment, a surface of the sleeve is approximately flush with a surface of the catheter body.

Peripheral nerve field stimulation and spinal cord stimulation

The disclosure is directed to techniques for shifting between two electrode combinations. An amplitude of a first electrode combination is incrementally decreased while an amplitude of a second, or subsequent, electrode combination is concurrently incrementally increased. Alternatively, an amplitude of the first electrode combination is maintained at a target amplitude level while the amplitude of the second electrode combination is incrementally increased. The stimulation pulses of the electrode combinations are delivered to the patient interleaved in time. In this manner, the invention provides for a smooth, gradual shift from a first electrode combination to a second electrode combination, allowing the patient to maintain a continual perception of stimulation. The shifting techniques described herein may be used during programming to shift between different electrode combinations to find an efficacious electrode combination. Additionally, the techniques may be used for shifting between different electrode combinations associated with different stimulation programs or program sets.
