Patent number: 10742205Abstract: Systems and methods for operating switches of a power supply are disclosed. The method includes generating power with a power source and switchably coupling the power source to an output of the power supply. One or more switches are opened and closed to generate a voltage waveform at the output, and in addition, the one or more switches are opened and closed to reduce a temperature differential that occurs between a low temperature and a high temperature of each switch by increasing the low temperature of each switch.Type: GrantFiled: September 16, 2019Date of Patent: August 11, 2020Assignee: Advanced Energy Industries, Inc.Inventor: Harley White

Patent number: 8731661Abstract: Various approaches are described for managing refractory periods based on the detection of an evoked response. The heart is paced and an evoked response is detected. At least one refractory period is adapted based on the detected evoked response. Adapting the refractory period may involve, for example, initiating a refractory period, terminating a refractory period, extending a refractory period or modifying one or more parameters of the refractory period. Adapting the refractory period may involve modifying a sensing threshold based on the detected evoked response. The sensing threshold of an atrial sensing channel may be adjusted, for example, to avoid sensing a ventricular evoked response on the atrial channel while allowing sensing of a P-wave on the atrial channel.Type: GrantFiled: July 19, 2011Date of Patent: May 20, 2014Assignee: Cardiac Pacemakers, Inc.Inventor: Harley White

Patent number: 8301251Abstract: Methods and systems are directed to detecting atrial tachyarrhythmia. A plurality of A-A intervals is detected. The detected A-A intervals are selected and used to detect atrial tachyarrhythmia. Selecting A-A intervals may be based on determining that A-A intervals are qualified. Qualified A-A intervals may be determined if a duration of the particular A-A interval falls outside a predetermined duration range, for example. Qualified A-A intervals may also be determined based on events occurring between consecutively sensed atrial events of the particular A-A interval, and whether the duration of the particular A-A interval falls within the predetermined duration range, for example.Type: GrantFiled: October 18, 2011Date of Patent: October 30, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Jaeho Kim, Joseph Bocek, Anthony Harrington, Harley White

Patent number: 8214027Abstract: A method and system provides for generating a snapshot representative of one beat of a patient's normal cardiac rhythm. Cardiac rate channel signals and shock channel signals are sensed. A fiducial point is determined for a predefined number of the cardiac rate channel signals. A predefined number of the shock channel signals are aligned using the fiducial point. A template is generated using the aligned shock channel signals, whereby the template is representative of one of the patient's normal supra-ventricular conducted cardiac beats. The template is updated on a periodic basis.Type: GrantFiled: April 7, 2008Date of Patent: July 3, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Jaeho Kim, William Hsu, Joseph Bocek, Harley White

Patent number: 7962209Abstract: A method and system for generating a characterization of one beat of a patient's supraventricular rhythm (SVR) involves performing such characterization while the heart is being paced. During SVR characterization, various pacing parameters are modified and the patient's supraventricular rhythm is characterized while the pacing parameters are modified. The SVR characterization process is effective in single and multiple chamber pacing modes.Type: GrantFiled: September 10, 2008Date of Patent: June 14, 2011Assignee: Cardiac Pacemakers, Inc.Inventors: Joseph Bocek, Jaeho Kim, Anthony Harrington, Harley White, Dave Perschbacher, Rebecca Davis

Publication number: 20080243201Abstract: A combination pacer/defibrillator is tailored for bradycardia patients. In one example, its shock-delivery specificity exceeds its sensitivity to shockable ventricular tachyarrhythmias. In another example, its specificity exceeds 95%, or 99%, or even 99.5%. Sensitivity is programmed to a high desired sensitivity value, but only if it can be done without decreasing the specificity below the desired specificity threshold value. This can be conceptualized as “avoiding at all costs” delivering false shocks, even at the expense of failing to deliver a shock to a treatable ventricular tachyarrhythmia. Specificity enhancements include, among other things, inhibiting shock delivery when the patient is breathing or not supine, using multiple channels or a high rate VT/VF detection threshold.Type: ApplicationFiled: June 9, 2008Publication date: October 2, 2008Applicant: Cardiac Pacemakers, Inc.Inventors: Joseph M.

Patent number: 6928323Abstract: A cross-chamber refractory period with an adaptively adjusted sensing threshold for use by a cardiac pacemaker is disclosed. In response to a cross-chamber event, the sensing threshold of a sensing channel is raised to an adaptively adjusted cross-chamber maximum refractory value. The cross-chamber maximum refractory value is derived from a peak amplitude measurement of the far-field signal resulting from the cross-chamber event.Type: GrantFiled: December 30, 2002Date of Patent: August 9, 2005Assignee: Cardiac Pacemakers, Inc.Inventors: Jaeho Kim, Harley White, Anthony Harrington, Joseph M.
