International Classification:

A61B 5/04
A61B 5/0464

US Classification:

600518, 600515

Abstract:

An arrhythmia classification system receives cardiac data from an implantable medical device, performs automatic adjudication of each cardiac arrhythmia episode indicated by the cardiac data, and generates episode data representative of information associated with the episode. The episode data include at least an episode classification resulting from the automatic adjudication of the episode and a confidence level in the episode classification. In one embodiment, the episode data further include key features rationalizing the automatic adjudication of the episode.

Paula A. Dassbach - Minneapolis MN, US
Abbey B.H. Becker - Shoreview MN, US
Christopher L. Pulliam - Plymouth MN, US

International Classification:

A61N 1/04
A61N 1/05

Abstract:

Implantable medical leads include rows of electrode segments where electrode segments within a given row may be a different size and/or adjacent electrode segments of adjacent rows may be of a different size. The arrangement of the electrode segments of different sizes may avoid intersections of the spaces between segments to reduce the size and/or number of blind spots that otherwise occur for delivery of stimulation signals and/or sensing of physiological signals. The electrode segments of different sizes may be of a same shape type but with different proportions.

International Classification:

A61N 1/36
A61N 1/372

Abstract:

A method for assessment of brain signals of a patient includes determining, by one or more processors, a cluster of neural data occurring at a brain of the patient and outputting, by the one or more processors, a request for a user to provide patient state information for the cluster of the neural data in response to determining that the cluster of the neural data is occurring at the brain of the patient. The method further includes associating, by the one or more processors, the patient state information with the cluster of the neural data to generate patient assessment information and outputting, by the one or more processors, the patient assessment information.

A61N 1/372

Abstract:

An example method includes determining, by an implantable medical device (IMD), an electrode of a plurality of electrodes of a lead to be used to deliver electrical stimulation to a patient at a particular time; selecting, by the IMD and based on the determined electrode, a set of electrodes of the plurality of electrodes; and sensing, by the IMD and via the selected set of electrodes, electrical signals of the patient at the particular time.

A61N 1/02

Abstract:

A medical device for providing electrical stimulation to a brain of a patient includes one or more processors. The one or more processors are configured to determine a first set of parameters of a first electrical signal that is delivered via a first electrode configured to apply electrical stimulation to a first region of the brain and to determine a second set of parameters of a second electrical signal based on the first set of parameters. The second electrical signal is delivered via a second electrode configured to apply electrical stimulation to a second region of the brain. The one or more processors are further configured to deliver, with the first electrode, the first electrical signal having the first set of parameters and to deliver, with the second electrode, the second electrical signal having the second set of parameters.

International Classification:

A61N 1/36
A61N 1/372
A61N 1/05

Abstract:

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 is configured to receive, for each electrode combination of a plurality of electrode combinations, information representing a signal sensed in response to first electrical stimulation delivered to a patient via a lead, wherein the plurality of electrode combinations comprise different electrode combinations comprising electrode disposed at different positions around a perimeter of the lead implanted in the patient. The system may also be configured to determine, based on the information for each electrode combination of the plurality of electrode combinations, values for a threshold at different locations around the perimeter of the lead and determine, based on the values for the threshold, one or more stimulation parameter values that at least partially define second electrical stimulation deliverable to the patient via the lead.
