A system is disclosed for determining a coverage of a target anatomical structure by an electric stimulation field. The system includes a computer to acquire patient image data and the atlas data, determine, based on the patient image data and the atlas data, target structure position data describing a position of the target anatomical structure in the medical image of the anatomical body part of the patient. The system also acquires electrode position data and stimulation field data describing an electric stimulation field around the position of the electrode. The system also includes an electrode configuring device for adjusting an emission configuration of the electrode.

The types of electrode leads that are connected to an implantable medical device are determined based on electrical parameters that are measured at the electrodes that are positioned on the leads. The different types of known electrode leads have different physical electrode arrangements that impact the measured electrical parameters. Properties in the measured electrical parameters that are indicative of the physical arrangements of electrodes of known types of electrode leads are utilized to determine the types of leads that are connected to the implantable medical device.

An example method includes delivering, by an implantable medical device and during a first period of time, high density electrical neurostimulation therapy to a patient using a first set of electrodes of a plurality of electrodes; and delivering, by the implantable medical device and during a second period of time, high density electrical neurostimulation therapy to the patient using a second set of electrodes of the plurality of electrodes.

Devices, systems, and techniques are disclosed for managing electrical stimulation therapy and/or sensing of physiological signals such as brain signals. For example, a system may assist a clinician in identifying one or more electrode combinations for sensing a brain signal. In another example, a user interface may display brain signal information and values of a stimulation parameter at least partially defining electrical stimulation delivered to a patient when the brain signal information was sensed.

Methods and systems for providing stimulation to a patient's brain using one or more electrode leads implanted in the patient's brain are described. The methods and systems help a clinician determine locations upon the lead where stimulation is expected to provide the best therapeutic benefit and the least side effects. Different locations upon the lead are used to provide stimulation and for each stimulation location evoked potentials are recorded. The evoked potentials are associated with likely beneficial therapeutic stimulation. Signals indicative of unwanted motor activity in the patient are also recorded for each of the stimulation locations. The recorded evoked potential signals and motor signals are used to determine stimulation locations that provide therapeutic benefit with minimal side effects. They can also be used to determine therapeutic windows for the potential stimulation locations.

We disclose the use of passive, or field-shaping electrodes, below the surface of the supporting structure of a cochlear implant. The location of the field-shaping electrodes below the surface of the supporting structure, allows for the use of the field-shaping electrodes to exist in the structure without decreasing the available space for the active, stimulating electrodes at the surface. The field-shaping electrodes are to direct the electric currents injected by the stimulating (active) electrodes onto the one-and-only-one neuron that is expected, by the brain, to receive vibrations from one-and-only-one frequency. The objective of the field-shaping electrodes is to prevent, or, at least to decrease, the leaking of the stimulating current from any stimulating active electrode onto any neuron other than the neuron that is directly in front of the electrode in question, which is the only neuron that is expected to receive excitation for that frequency associated with each electrode.

A system for restoring muscle function to the lumbar spine to treat low back pain is provided. The system may include electrodes coupled to an implantable pulse generator (IPG), a handheld activator configured to transfer a stimulation command to the IPG, and an external programmer configured to transfer programming data to the IPG. The stimulation command directs the programmable controller to stimulate the tissue in accordance with the programming data. The system may include a software-based programming system run on a computer such that the treating physician may program and adjust stimulation parameters.

A lead body is operable to be implanted proximate a target nerve tissue of a patient. A sensing electrode is configured to sense biopotentials over a first partial circumference of the lead body. A stimulation electrode is configured to deliver stimulation energy over a second partial circumference of the lead body. A signal generator is electrically coupled to the stimulation electrode and a sensing circuit is coupled to the sensing electrode. A processor is operable to apply a stimulation signal to the stimulation electrode via the signal generator and, via the sensing circuit, sense an evoked response to the stimulation signal that propagates along a neural pathway.

A device and means to decrease the pain associated with colonoscopy and similar procedures to examine the oesophagus, the stomach, etc. The device uses electrical currents of both positive and negative polarity, or alternating current. The improvement described can be incorporated into existing bodies of existing devices. Application on colonoscopy screenings and intestine polyp collection and other types of biopsies.

Disclosed is an artificial retinal stimulator and an artificial retinal device which are for providing image jittering. The artificial retinal stimulator for providing the image jittering includes: a photodiode configured to sense light stimulation and generate a current based on an intensity of the stimulation; a pulse generator configured to generate a pulse to be provided to a corresponding stimulation electrode on the basis of the current coming from the photodiode; a switch configured to connect an output terminal of the pulse generator and ground; and a jittering switch configured to determine whether to transfer the generated pulse to the corresponding stimulation electrode or to transfer to a stimulation electrode corresponding to another artificial retinal stimulator. According to the present disclosure, an image jittering function capable of emulating an eye blinking effect is provided, so that it is possible to enable a low vision patient to see images better.
