Techniques for modeling therapy fields for therapy delivered by medical devices are described. Each therapy field model is based on a set of therapy parameters and represents where therapy will propagate from the therapy system delivering therapy according to the set of therapy parameters. Therapy field models may be useful in guiding the modification of therapy parameters. As one example, a processor compares an algorithmic model of a therapy field to a reference therapy field and adjusts at least one therapy parameter based on the comparison. As another example, a processor adjusts at least one therapy parameter to increase an operating efficiency of the therapy system while substantially maintaining the modeled therapy field.

The present disclosure provides systems and methods for selecting contacts for use in deep brain stimulation (DBS). A computing device includes a processor and a memory device communicatively coupled to the processor. The memory device includes instructions that, when executed, cause the processor to apply a spatial filter to local field potential (LFP) recordings for a plurality of contacts of a DBS lead, calculate a power spectral density (PSD) for each contact from the filtered LFP for that contact, calculate a parametric approximation for each PSD, select at least one frequency band based on the parametric approximations, calculate a spectral coherency matrix for each of the at least one selected frequency band, and calculate an eigenvector centrality for each spectral coherency matrix to facilitate identifying a contact for stimulation.

Systems and methods are provided for treating a sexual disorder such as erectile dysfunction (ED) or female sexual arousal disorder (FSAD). An electrical stimulation system may include an implantable stimulation unit, an external patient controller, and an external physician controller. The implantable stimulation unit has an array of electrodes disposed on one or more flexible substrates configured to conform to a patient's anatomy at the pelvic plexus. Post-implantation, the physician controller may direct the stimulation unit to stimulate with select electrode(s) of the array to determine which electrode configuration provides optimal sexual arousal. The patient controller may be used to cause the stimulation unit to stimulate using the optimal electrode configuration at desired times.

An implantable antibacterial barrier device for an elongated medical device, the elongated medical device configured to extend from a first site, through a second site, to a third site. The implantable antibacterial barrier device includes a housing configured to be disposed at the first site, a working electrode configured to be disposed at the second site, and a reference electrode configured to be disposed at the first site. The housing includes barrier circuitry. The working electrode electrically is coupled to the barrier circuitry. The reference electrode is electrically coupled to the barrier circuitry. The barrier circuitry is configured to selectively maintain the working electrode at a negative electrical potential relative to the reference electrode to form an antibacterial barrier.

Distributed electrode lead configurations for providing electrical therapy, and associated systems and methods. A representative patient therapy system includes at least one implantable signal delivery device having a proximal portion and a distal portion. The proximal portion is configured to be coupled with an implantable pulse generator to direct a pulsed electrical signal at a frequency from about 1.5 kHz to about 100 kHz. The distal portion includes multiple electrical contacts for delivering the pulsed electrical signal to a target neural population of a patient when implanted. At least three neighboring electrical contacts of the multiple electrical contacts are electrically connected together and have equal lengths less than 3 mm. The at least three neighboring electrical contacts are uniformly spaced apart by a distance from about 1 mm to about 8 mm.

An implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body has a programmable signal generator that can generate the signals based on stored signal parameters without any intervention from a processor that controls the overall operation of the IPG. While the signal generator is generating the signals the processor can be in a standby mode to substantially save battery power. The IPG also contains circuitry to indicate to a patient that proper alignment exists between the IPG and an external charger to charge a battery in the IPG.

A model of an implantable lead is provided via a graphical user interface. The implantable lead is configured to deliver electrical stimulation to a patient via a plurality of electrodes located on the implantable lead. The graphical user interface also provides a plurality of predefined electrode activation patterns that include a coarse pattern and a refined pattern. The coarse pattern corresponds to a first group of electrodes located in a first region of the implantable lead. The refined pattern corresponds to a second group of electrodes located in a second region of the implantable lead. The second region is smaller than, and is a subsection of, the first region. A coarse testing process is performed by selectively activating the first group of electrodes belonging to the coarse pattern. Thereafter, a refined testing process is performed by selectively activating the second group of electrodes belonging to the refined pattern.

The disclosure is directed to programming implantable stimulators to deliver stimulation energy via one or more implantable leads having complex electrode array geometries. The disclosure also contemplates guided programming to select electrode combinations and parameter values to support efficacy. The techniques may be applied to a programming interface associated with a clinician programmer, a patient programmer, or both. A user interface permits a user to view electrodes from different perspectives relative to the lead. For example, the user interface provides a side view of a lead and a cross-sectional view of the lead. The user interface may include an axial control medium to select and/or view electrodes at different axial positions along the length of a lead, and a rotational control medium to select and/or view electrodes at different angular positions around a circumference of the lead.

A medical device provides stimulation therapy to a patient based on a set of therapy parameters. One or more therapy parameters may be automatically adjusted based on acceleration forces detected by a sensor, the acceleration forces being applied to the patient. In some examples, adjustments to one or more therapy parameter may be made based on an algorithm. The algorithm may be defined by acceleration and therapy parameter value pairs associated with opposite patient positions.

An example of a system may include an electrode arrangement, a neural modulation generator configured to use electrodes in the electrode arrangement to generate a modulation field, a communication module configured to receive commands, a memory configured to store modulation field parameter data, and a controller configured to control the neural modulation generator to generate the modulation field. The controller may be configured to implement a trolling routine to troll the modulation field through neural tissue positions, and implement a marking routine multiple times as the modulation field is trolled through the neural tissue positions to identify when the modulation field provides patient-perceived modulation. The marking procedure implemented by the controller may receive a marking command that indicates that a modulation intensity achieved the patient-perceived modulation, and store in the memory the modulation field parameter data that affects the modulation intensity in response to receiving the marking command.
