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.

Systems and methods for presenting electrostimulation data and patient clinical responses to electrostimulation are disclosed. A system comprises an implantable stimulator, and a programming device including a controller to identify first and second sets of base stimulation settings each comprising an electrode configuration and stimulation parameter values selected from a configuration and parameter search space. The controller can detect clinical effects and evaluate a clinical response indicator in response to electrostimulation for each base stimulation setting of the first set, and predict clinical effects and estimate a clinical response indicator without delivering electrostimulation for each base stimulation setting of the second set. Based on the clinical response indicators, the controller can determine characteristic stimulation amplitudes for one or more electrode configurations. A formatted monopolar review report comprising the characteristic stimulation amplitudes can be displayed to the user.

Disclosed are methods and systems for treating epilepsy by stimulating a main trunk of a vagus nerve, or a left vagus nerve, when the patient has had no seizure or a seizure that is not characterized by cardiac changes such as an increase in heart rate, and stimulating a cardiac branch of a vagus nerve, or a right vagus nerve, when the patient has had a seizure characterized by cardiac changes such as a heart rate increase.

A method for titrating a stimulation parameter for one or more electrode contacts in a system for stimulating a hypoglossal nerve of a patient includes activating one of the one or more electrode contacts to stimulate the hypoglossal nerve of the patient, obtaining a first and/or second physiological measurement from the patient, comparing the first and/or second physiological measurement to a first and/or second predetermined target value, adjusting a stimulation parameter for the one of the one or more electrode contacts if the first and/or second physiological measurement differs from the first and/or second predetermined target value.

This application is generally related to systems and methods for providing a medical therapy to a patient by tracking patient activity and adjusting medical therapy based on occurrence of different types of activities performed by the patient while automatically rescheduling stimulation programs based on detected patient activity.

A system for visualizing clinical effects can perform the following actions: obtain, for each of multiple stimulation instances, an estimation of a region stimulated during the stimulation instance and at least one assessment for at least one stimulation effect or stimulation side effect; assign, for each of the stimulation instances, a tag, selected from multiple tags, to each one of multiple voxels within the region stimulated during the stimulation instance, where the tag is selected based on the at least one assessment for the stimulation instance; and assign a voxel type, selected from multiple voxel types, to each of multiple voxels based on the tags assigned to the voxels. Optionally, the actions can also include display, on a display, a representation of multiple voxels with each of the displayed voxels having a graphical feature associated with the voxel type assigned to that voxel.
