Described are methods, devices, and systems for a novel, inexpensive, easy to use therapy for a number of disorders. Described are methods and devices to treat disorders that involves no medication. Methods and devices described herein use alternating magnetic fields to gently tune the brain and affect mood, focus, and cognition of subjects.

A spine measurement system comprising a camera, an encoded collar, and a remote station. A rod is shaped having one or more bends to modify a curvature of a spine. The encoded collar is coupled to the rod. The encoded collar includes a plurality of markings where each marking represents a rod position. The rod and encoded collar are in a field of view of the camera. The camera takes a number of images as the rod rotates at least 360 degrees. The remote station measures the 2D images to produce quantitative measurements that yield a 3D model of the rod shape. The remote station can use the 3D rod shape to determine metrics that relate to how the rod shapes the spine. For example, a Cobb angle can be calculated from the rod shape to determine if the rod yields the desired spine outcome.

A system and methods for performing neurophysiologic assessments during surgery, such as assessing the health of the spinal cord via at least one of MEP and SSEP monitoring and assessing bone integrity, nerve proximity, neuromuscular pathway, and nerve pathology during spine surgery.

A spinal implant includes a link having a first surface and a second surface connectable with a spinal construct. The spinal construct is attachable with one or more vertebral levels. A plurality of electrodes includes at least one electrode disposed with the first surface and at least one electrode disposed with the second surface such that the electrodes conduct an electric current to stimulate tissue growth adjacent the spinal construct. Systems, surgical instruments and methods are disclosed.

Example systems and techniques for denervation, for example, renal denervation. In some examples, a processor determines one or more tissue characteristics of tissue proximate a target nerve and a blood vessel. The processor may generate, based on the one or more tissue characteristics, an estimated volume of influence of denervation therapy delivered by a therapy delivery device disposed within the blood vessel. The processor may generate a graphical user interface including a graphical representation of the tissue proximate the target nerve and the blood vessel and a graphical representation of the estimated volume of influence.

In embodiments, devices, methods and systems to analyze the different mediums of brain function in a mathematically uniform manner may be provided. For example, in an embodiment, a computer-implemented method for determining structure of living neural tissue may comprise receiving at least one signal from at least one read modality, the signal representing at least one physical condition of the living neural tissue, determining action potentials based on the signals received from the read modalities, determining frequency oscillations based on the signals received from the read modalities and the action potentials, determining neuron network structures based on the photonic signals received from the read modalities, the action potentials, and the frequency oscillations, wherein the neuron network structures are determined using a Maximum Entropy model, and mapping brain region activation by S+/R? events to observable linguistic events using the Maximum Entropy model.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, ultra-MIS techniques.

Embodiments of the present systems and methods may relate to a non-invasive system with diagnostic and treatment capacities that use a unified code that is intrinsic to physiological brain function. For example, in an embodiment, a computer-implemented method for affecting living neural tissue may comprise receiving at least one signal from at least one read modality, the signal representing release of photons from mitochondria of the living neural tissue, computing at least one signal to effect alterations to the living neural tissue based on the received input signal, the computed signal adapted to cause transmission of photons to the living neural tissue, and delivering the photons to the living neural tissue to effect alterations to the living tissue.

Incorrect connection or mapping of leads' proximal terminals to the ports of an Implantable Stimulator Device (ISD), such as an implantable pulse generator or an external trial stimulator, is a concern, and this disclosure is directed to use of measurement and identification algorithms to either determine that leads are properly connected to their assigned ISD ports, or to determine which leads are connected to the ports even if the leads are not preassigned to the ports. Particular focus is given in the disclosed technique to assessing leads that comprise larger number of electrodes than are supported at each port, and thus have more than one proximal terminal that connect to more than one port of the ISD.
