Patent number: 11779755Abstract: A system and method for providing electrical stimulation to biological tissue to treat medical conditions. The system can include a lead configured to be positioned in contact with biological tissue proximate one or more occipital nerves, an implantable pulse generator configured to deliver electrical stimulation to the biological tissue via the one or more leads, and/or a power source configured to operatively connect and supply power to the implantable pulse generator. The system can further include a processor configured to communicate with the implantable pulse generator. The processor can operate the implantable pulse generator to deliver the electrical stimulation to the biological tissue via the lead. The implantable pulse generator can deliver the electrical stimulation by applying a stimulation waveform or a stimulation pattern. The stimulation waveform can include a series of stimulation pulses that can vary over time, which can reduce an effect of neural accommodation or adaptation.Type: GrantFiled: April 24, 2018Date of Patent: October 10, 2023Assignee: NeoGenesis Technologies LLCInventors: Martin Cholette, Gary Dulak

Patent number: 9044610Abstract: Techniques are provided for controlling and delivering spinal cord stimulation (SCS) or other forms of neurostimulation. In one example, neurostimulation pulses are generated wherein successive pulses alternate in polarity so that a pair of electrodes alternate as cathodes. Each pulse has a cathodic amplitude sufficient to achieve cathodic capture of tissues adjacent the particular electrode used as the cathode for the pulse. The neurostimulation pulses are delivered to patient tissues using the electrodes to alternatingly capture tissues adjacent opposing electrodes via cathodic capture to achieve a distributed virtual stimulation cathode. Various pulse energy savings techniques are also set forth that exploit the distributed virtual stimulation cathode.Type: GrantFiled: March 25, 2013Date of Patent: June 2, 2015Assignee: PACESETTER, INC.Inventors: Stuart Rosenberg, Martin Cholette, Xiaoyi Min

Patent number: 8923965Abstract: Systems and methods are provided wherein intracardiac electrogram (IEGM) signals are used to determine a set of preliminary optimized atrioventricular (AV/PV) and interventricular (VV) pacing delays. In one example, the preliminary optimized AV/VV pacing delays are used as a starting point for further optimization based on impedance signals such as impedance signals detected between a superior vena cava (SVC) coil electrode and a device housing electrode, which are influenced by changes in stroke volume within the patient. Ventricular pacing is thereafter delivered using the AV/VV pacing delays optimized via impedance. In another example, parameters derived from IEGM signals are used to limit the scope of an impedance-based optimization search to reduce the number of pacing tests needed during impedance-based optimization. Biventricular and multi-site left ventricular (MSLV) examples are described.Type: GrantFiled: December 22, 2010Date of Patent: December 30, 2014Assignee: Pacesetter, Inc.Inventors: Xiaoyi Min, Gene A.

Patent number: 8868184Abstract: A set of cardiogenic impedance signals are detected along different sensing vectors passing through the heart of the patient, particularly vectors passing through the ventricular myocardium. A measure of mechanical dyssynchrony is detected based on differences, if any, among the cardiogenic impedance signals detected along the different vectors. In particular, differences in peak magnitude delay times, peak velocity delay times, peak magnitudes, and waveform integrals of the cardiogenic impedance signals are quantified and compared to detect abnormally contracting segments, if any, within the heart of the patient. Warnings are generated upon detection of any significant increase in mechanical dyssynchrony. Diagnostic information is recorded for clinical review. Pacing therapies such as cardiac resynchronization therapy (CRT) can be activated or controlled in response to mechanical dyssynchrony to improve the hemodynamic output of the heart.Type: GrantFiled: September 2, 2011Date of Patent: October 21, 2014Assignee: Pacesetter, Inc.Inventor: Martin Cholette

Patent number: 8838241Abstract: Stimulation of a patient's nervous system is controlled based on cardiovascular risk assessment performed by an implantable medical device. For example, an implantable medical device may monitor cardiac electrical activity to detect changes in the ST segment. Upon detection of a certain change in the ST segment, the implantable medical device controls the application of spinal cord stimulation and/or other neurostimulation to cardiac-related sections of the patient's nervous system. In some embodiments, the implantable medical device communicates with a separate neurostimulation device to control the neurostimulation. In some embodiments, the implantable medical device delivers the neurostimulation.Type: GrantFiled: February 28, 2013Date of Patent: September 16, 2014Assignee: Pacesetter, Inc.Inventors: Lanitia Ness, Martin Cholette

Patent number: 8649851Abstract: The invention is directed towards measuring current of injury (COI) during lead fixation. A baseline waveform is sensed from a lead while the lead is in a pre-fixation position. The baseline waveform represents an interface between the lead and tissue proximate a lead prior to active fixation. Cardiac signals are then sensed when the lead is in a post-fixation position. The post-fixation waveform represents an interface between the lead and the tissue once the lead is actively attached to the tissue. A COI is calculated based on an automatic comparison of the baseline and post-fixation waveforms. A COI feature of interest is identified in the baseline and post-fixation waveforms and a COI index, a COI area, a COI differential and/or a COI ratio is calculated based on the COI feature of interest in the baseline and post-fixation waveforms.Type: GrantFiled: September 15, 2010Date of Patent: February 11, 2014Assignee: Pacesetter, Inc.Inventor: Martin Cholette
