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.
TOOL TO USE IMAGE FOR PROGRAMMING NEUROMODULATION
A system may be used with a medical imaging system and a programming system. The medical imaging system may be configured to display a medical image and the programming system may be configured to implement a program used in programming a neuromodulation device. The system may comprise a mobile device having at least one processor, a camera and a user interface including a display. The mobile device may be configured to acquire a displayed medical image from the medical imaging system, determine based on the acquired medical image location data indicative of the position of at least one of the electrodes relative to at least one of the anatomy or at least another one of the electrodes, and provide the location data for use by the program implemented by the programming system.
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.
Electrical stimulator configuration with initial high-density stimulation
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.
System and methods for heart rate and electrocardiogram extraction from a spinal cord stimulation system
A system and method for extracting a cardiac signal from a spinal signal include measuring a spinal signal at one or more electrodes that are connected to a neurostimulator and implanted within a patient's spinal canal and processing the spinal signal to extract the cardiac signal, which includes features that are representative of the patient's cardiac activity. Processing the spinal signal to extract the cardiac signal can include filtering the spinal signal, or use of model reduction schemes such as independent component analysis. The extracted cardiac signal can include a number of features that correspond to an electrocardiogram and can be used to determine the patient's heart rate and/or to detect a cardiac anomaly. Cardiac features that are determined from the cardiac signal can additionally be used to adjust parameters of the stimulation that is provided by the neurostimulator.

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.
APPARATUS FOR PERIPHERAL OR SPINAL STIMULATION
Provided herein are methods of treating a patient comprising providing a medical apparatus comprising an external system and an implantable system, implanting the implantable system, and delivering at least one of power or data to the implantable system with the external system. The external system comprises: at least one external antenna configured to transmit a first transmission signal to the implantable system; an external transmitter configured to drive the at least one external antenna; an external power supply; and an external controller. The implantable system comprises: at least one implantable antenna configured to receive the first transmission signal from the first external device; an implantable receiver; at least one implantable functional element configured to interface with the patient; an implantable controller; an implantable energy storage assembly; and an implantable housing surrounding at least the implantable controller and the implantable receiver. Medical apparatus are also provided.
SYSTEMS AND METHODS FOR RESTORING MUSCLE FUNCTION TO THE LUMBAR SPINE
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.
SYSTEM AND METHOD FOR MODULATING THERAPY IN A REMOTE CARE ARCHITECTURE
A system and method for modulating delivery of remote therapy to a patient having an implantable medical device (IMD). Upon establishing a remote care session between a patient controller device and a clinician programmer, wherein the clinician and the patient are remotely located with respect to each other, a determination may be made if a first triggering event is detected. Responsive to the determination, a remote therapy session used for programming the patient's IMD is paused and one or more remote care therapy setting controls provided at the clinician programmer device to facilitate one or more adjustments with respect to the patient's IMD are disabled. Subsequently, responsive to detecting a second triggering event, the remote therapy session with the patient may be resumed, wherein the one or more remote care therapy setting controls of the clinician programmer device are enabled.
