Abstract: A medical lead includes a plurality of electrodes on an annular distal end portion of the lead. The electrodes may be arranged along a circle concentric with the center of a void defined by the annular portion. The annular medical lead design is well suited for application of electrical signal therapy to the suborbital nerve at its point of exit from the inferior orbital foramen in the skull.

Abstract: Devices, systems, and techniques for delivering electrical stimulation according to a spatial electrode movement pattern are disclosed. Moving electrical stimulation between electrodes in a repeatable movement pattern may provide a therapeutic sensation to a patient. In one example, a system may include a plurality of electrodes configured to be implanted within a patient, at least one processor, and a therapy module. The at least one processor may be configured to receive a spatial electrode movement pattern that defines a sequence with which electrical stimulation is moved between the plurality of electrodes. The therapy module may be configured to deliver electrical stimulation to the patient based on the spatial electrode movement pattern.

Abstract: Devices, systems, and techniques for ramping one or more parameter values of electrical stimulation are disclosed. An implantable medical device may increase or decrease a parameter value, e.g., amplitude or pulse width, over time to reach a target value of the parameter. In one example, a memory may be configured to store a plurality of amplitude ramp schedules. At least one processor may be configured to obtain a stimulation parameter set that at least partially defines an electrical stimulation therapy, select one of the plurality of amplitude ramp schedules based on a signal frequency of the stimulation parameter set, and increase an amplitude of the electrical stimulation therapy during a ramp period defined by the selected amplitude ramp schedule.

Abstract: In some examples, the disclosure relates to system, devices, and techniques for delivering dorsal column stimulation. One or more locations for dorsal column stimulation may be identified based on sensed signals evoked by delivery of stimulation to a dorsal root and/or peripheral nerve of a patient. In some examples, an IMD may deliver dorsal column stimulation in combination with dorsal root stimulation to a patient to treat a patient condition.

Abstract: A medical lead includes a lead body having a proximal end for electrical connection to an implantable electric signal generator and a distal end portion having a plurality of electrodes extending in a helical manner longitudinally along the distal end portion. Adjacent helical electrodes may be offset, for example, 90 degrees or 180 degrees. The helical electrodes may extend less than, greater than, or 360 degrees. The electrode arrangement provides increased surface area, improving the capability of positioning the lead against the nerve as desired.

Abstract: A hub (200) includes a first lead receptacle having a plurality of contacts (280) for electrically coupling a lead to an implantable electrical device. The hub further contains a second lead receptacle having a plurality of contacts for electrically coupling a lead to the implantable electrical device. At least one of the plurality of contacts of the first receptacle is a contact of the second receptacle. Such a configuration may allow for the overall size of the hub to be reduced relative to a hub where each discrete contact of the hub corresponds to a discrete contact or electrical channel of the implantable electrical device.

Abstract: An introducer for a medical lead, the introducer having an arcuate component for creating an arcuate path in a patient. When used to percutaneously implant a medical device such as a medical lead with electrodes, the implanted lead has an arcuate configuration. The implanted lead can be used to at least partially encircle or bracket a region of chronic pain and provide therapeutic electrical signals to the region.
