Patent number: 11110280Abstract: Methods and systems for selecting stimulation parameters using targeting and steering techniques are presented. For example, a method or system (via actions performed by a processor) can include receiving a name of an anatomical or physiological target or a name of a disease or disorder; receiving a clinical goal; and using at least 1) the anatomical or physiological target or disease or disorder and 2) the clinical goal, selecting a set of stimulation parameters. Another method or system (via actions performed by its processor) can include receiving a first set of stimulation parameters; receiving a command to alter the first set of stimulation parameters that does not include, or is not composed exclusively of, a numerical value for any of the stimulation parameters; and modifying the first set of stimulation parameters to create a second set of stimulation parameters based on the command.Type: GrantFiled: August 9, 2019Date of Patent: September 7, 2021Assignee: Boston Scientific Neuromodulation CorporationInventor: G. Karl Steinke

Patent number: 11083372Abstract: A system includes an implantable medical device configured to sense a sync signal and sense physiological parameters to obtain a physiological signal. In response to sensing the sync signal, the implantable medical device is configured to generate a sync-stamped physiological signal. In certain embodiments, a method includes receiving a first physiological signal coupled with a sync signal; receiving a second physiological signal coupled with the sync signal; and, using the sync signal, synchronizing in time the first and second physiological signals.Type: GrantFiled: January 7, 2017Date of Patent: August 10, 2021Assignee: Cardiac Pacemakers, Inc.Inventors: Pramodsingh H. Thakur, David J. Ternes, Keith R. Maile, Zhe Shen, Stephen B. Ruble, Howard D. Simms, Paul F. Emerson

Patent number: 11083887Abstract: Incorrect connection or mapping of leads' proximal terminals to the ports of an Implantable Stimulator Device (ISD), such as an implantable pulse generator or an external trial stimulator, is a concern, and this disclosure is directed to use of measurement and identification algorithms to either determine that leads are properly connected to their assigned ISD ports, or to determine which leads are connected to the ports even if the leads are not preassigned to the ports. Particular focus is given in the disclosed technique to assessing leads that comprise larger number of electrodes than are supported at each port, and thus have more than one proximal terminal that connect to more than one port of the ISD.Type: GrantFiled: September 11, 2018Date of Patent: August 10, 2021Assignee: Boston Scientific Neuromodulation CorporationInventors: Kelsey Bower, G. Karl Steinke, Hemant Bokil, Ara Sarian

Patent number: 11071868Abstract: A neurostimulation system includes a programming control circuit and a user interface. The programming control circuit may be configured to generate a plurality of stimulation parameters controlling delivery of neurostimulation pulses according to one or more neurostimulation programs each specifying a pattern of the neurostimulation pulses. The user interface includes a display screen, a user input device, and a neurostimulation program circuit. The neurostimulation program circuit may be configured to allow for construction of one or more pulse trains (PTs) and one or more train groupings (TGs) of the one or more neurostimulation programs, and to allow for scheduling of delivery of the one or more neurostimulation programs, using the display screen and the user input device. Each PT includes one or more pulse blocks each including a plurality of pulses of the neurostimulation pulses. Each TG includes one or more PTs.Type: GrantFiled: May 13, 2019Date of Patent: July 27, 2021Assignee: Boston Scientific Neuromodulation CorporationInventor: David Ernest Wechter

Patent number: 11040721Abstract: Methods for management of a powertrain system in a vehicle. The methods receive data or signals from multiple sensors associated with the vehicle. Optimum thresholds for classifications of the sensor data can be changed based injecting signals into the powertrain system and receiving responsive signals. Expected priorities for the sensor signals can be altered based upon attributes of the signals and confirming actual priorities for the signals. Look-up tables for engine management can be modified based upon injecting signals into the powertrain system and measuring a utility of the responsive signals. The methods can thus dynamically alter and modify data for powertrain management, such as look-up tables, during vehicle operation under a wide range of conditions.Type: GrantFiled: November 27, 2018Date of Patent: June 22, 2021Assignee: 3M Innovative Properties CompanyInventors: Gilles J.
