Abstract: This specification describes systems, methods, devices, and other techniques for activating muscle groups in a mammal using an implantable epidural electrical stimulation (EES) system, and for using spinal landmarks to determine implant locations for an EES probe. In some aspects, a first set of electrodes of an EES system is provided at a first set of locations on the dura mater of a spine of a mammal, the first set of locations on the dura mater corresponding to a first muscle group of the mammal, a second set of electrodes is provided at a second set of locations on the dura mater of the spine of the mammal, the second set of locations on the dura mater corresponding to a second muscle group of the mammal, and the first and second sets of locations on the dura mater are stimulated by electrically energizing the first and second sets of electrodes.

Abstract: Image-guided navigation for spinal cord treatments and therapies are described. The image-guided navigation is augmented with anatomical measurement data related to spinal cord and vertebral anatomy. From these data and medical image data, an augmented model of spinal cord anatomy is generated and/or navigation data can be generated for localizing spinal cord structures, such as by mapping the anatomical measurement data to the medical image data. The augmented model data and/or navigation data can be used for surgical navigation, stimulation parameter setting, electrode configuration selection, pre-surgical planning, surgical visualization, and so on.

Abstract: Functional ultrasound imaging (“fUS”) is used to facilitate the placement of electrodes for spinal cord stimulation and to optimize and update stimulation parameters for spinal cord stimulation devices.

Abstract: Epidural electrical stimulation (EES) systems and techniques for accessing and locating targeted spinal cord segments are disclosed. In some examples, a method includes providing a first set of electrodes of an EES system at a first set of locations on the dura mater of a spine of a mammal, the first set of locations on the dura mater corresponding to a first muscle group of the mammal; providing a second set of electrodes of the epidural electrical stimulation system at a second set of locations on the dura mater of the spine of the mammal, the second set of locations on the dura mater corresponding to a second muscle group of the mammal; and stimulating the first and second sets of locations on the dura mater by electrically energizing the first and second sets of electrodes, respectively, thereby activating the first and second muscle groups in a coordinated manner.

Abstract: An implantable electrode array assembly configured to apply electrical stimulation to the spinal cord. A substantially electrically nonconductive layer of the device has a first portion positionable alongside the spinal cord that includes a plurality of first openings. The layer has a second portion that includes a plurality of second openings. Electrodes and traces are positioned inside a peripheral portion of a body portion of the device and alongside the layer. At least one of the first openings is adjacent each of the electrodes to provide a pathway through which the electrode may provide electrical stimulation to the spinal cord. At least one of the second openings is adjacent each of the traces to provide a pathway through which the trace may receive electrical stimulation. At least one trace is connected to each electrode and configured to conduct electrical stimulation received by the trace(s) to the electrode.
