Simulating a Target Coverage for Deep Brain Stimulation
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.
Autotitration of therapy using detected electrical activity
This disclosure relates to devices, systems, and methods for autotitrating stimulation parameters. In one example, a method includes controlling an implantable medical device to deliver electrical stimulation to a patient according to a plurality of electrical stimulation parameter sets, each electrical stimulation parameter set of the plurality of electrical stimulation parameter sets defining a respective electrical stimulation signal deliverable to the patient, obtaining, by one or more processors and for each electrical stimulation parameter set of the plurality of electrical stimulation parameter sets, a respective signal representative of an electrical response sensed from the patient in response to the electrical stimulation delivered to the patient according to the respective electrical stimulation parameter set, and determining, by the one or more processors and based on the obtained respective signals, a primary electrical stimulation parameter set that defines electrical stimulation therapy deliverable to the patient by the implantable medical device.
System and method for determination of connected neurostimulation leads
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.
Power control circuit for sterilized devices, and associated systems and methods
A power control circuit for use with devices that will be placed in a flammable sterilizing gas includes a bi-stable switch that is configured to produce an output to place the circuitry of a connected device in a run state or a sleep state. The bi-stable switch controls one or more transistors to drain energy from energy storage devices in the circuitry of the connected device to a level below an ignition level of a sterilizing gas. A remotely actuatable switch can be actuated from outside of a packaging in which the power control circuit is placed to cause the bi-stable switch to produce an output that puts the circuitry in the run state without removing the power control circuit from the packaging.

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.
Using Evoked Potentials for Brain Stimulation Therapies
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.
SYSTEM AND METHOD TO HOLD TRIALING SYSTEM
Disclosed is a medical assembly, according to various embodiments, for providing a therapy to a subject. The assembly is operable to be held relative to a subject for a trial period. The holder may allow for connections and/or passage of connections from the medical device to allow for appropriate or a selected operation of the medical device.
