Patent number: 10413203Abstract: Some method examples may include pacing a heart with cardiac paces, sensing a physiological signal for use in detecting pace-induced phrenic nerve stimulation, performing a baseline level determination process to identify a baseline level for the sensed physiological signal, and detecting pace-induced phrenic nerve stimulation using the sensed physiological signal and the calculated baseline level. Detecting pace-induced phrenic nerve stimulation may include sampling the sensed physiological signal during each of a plurality of cardiac cycles to provide sampled signals and calculating the baseline level for the physiological signal using the sampled signals. Sampling the sensed physiological signal may include sampling the signal during a time window defined using a pace time with each of the cardiac cycles to avoid cardiac components and phrenic nerve stimulation components in the sampled signal.Type: GrantFiled: February 28, 2013Date of Patent: September 17, 2019Assignee: Cardiac Pacemakers, Inc.Inventors: Sunipa Saha, Yanting Dong, Holly Rockweiler

Patent number: 9878163Abstract: Systems and methods for providing CRT therapy to a patient with an implanted multi-site pacing medical device. In one example, an intrinsic electrical delay associated with each of two or more left ventricle electrodes may be determined. The intrinsic electrical delay associated with each of the two or more left ventricle electrodes may be compared to an electrical delay threshold. If the electrical delay associated with one or fewer left ventricle electrodes is greater than the electrical delay threshold, a single left ventricle electrode may be selected for use during subsequent CRT therapy. If the electrical delay associated with more than one left ventricle electrode is greater than the electrical delay threshold, two or more of the left ventricle electrodes may be selected for use during subsequent CRT therapy.Type: GrantFiled: September 27, 2016Date of Patent: January 30, 2018Assignee: Cardiac Pacemakers, Inc.Inventors: Yinghong Yu, Keith L. Herrmann, Holly Rockweiler, Sunipa Saha, Benjamin J Nyquist

Patent number: 9272151Abstract: An example of a system comprises a cardiac pulse generator configured to generate cardiac paces to pace the heart, a sensor configured to sense a physiological signal for use in detecting pace-induced phrenic nerve stimulation (PS), a storage, and a phrenic nerve stimulation detector. The storage is configured for use to store patient-specific PS features for PS beats with a desirably large signal-to-noise ratio. The phrenic nerve stimulation detector may be configured to detect PS features for the patient by analyzing a PS beat with a desirably large signal-to-noise ratio induced using a pacing pulse with a large energy output and store patient-specific PS features in the storage, and use the patient-specific PS features stored in the memory to detect PS beats when the heart is paced heart using cardiac pacing pulses with a smaller energy output.Type: GrantFiled: July 11, 2013Date of Patent: March 1, 2016Assignee: Cardiac Pacemakers, Inc.Inventors: Krzysztof Z.

The cardiac pace is delivered at the desired pacing time and nerve traffic in the phrenic nerve is inhibited at the desired nerve traffic inhibition time.Type: GrantFiled: December 2, 2013Date of Patent: February 9, 2016Assignee: Cardiac Pacemakers, Inc.Inventors: Juan Gabriel Hincapie Ordonez, Holly Rockweiler

Patent number: 9211415Abstract: A method and a system of phrenic nerve stimulation detection in conjunction with posture sensing is disclosed. In an embodiment, the method may include receiving a trigger for conducting a pace-induced phrenic nerve stimulation (PS) search using the IMD within the patient. On receiving the trigger, the IMD may be used for conducting the PS search. A procedure of conducting the PS search may include measuring a posture of the patient using an implantable posture sensor, searching for PS while the patient is in the measured posture and obtaining a PS result from the PS search for the measured posture. The method may include recording both the PS result and the measured posture in a memory of the IMD.Type: GrantFiled: February 26, 2014Date of Patent: December 15, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: Sunipa Saha, Holly Rockweiler, Aaron R.

Patent number: 9138585Abstract: An interactive representation of electrostimulation electrodes or vectors can be provided, such as for configuring combinations of electrostimulation electrodes. In an example, electrodes or test parameters can be presented graphically or in a table. A user interface can be configured to receive user-input designating electrode combinations or vectors for test or for use in programming an implantable or ambulatory medical device. The interface can be used to indicate suggested electrode combinations or vectors in response to a first selection of an electrode. Tests can be performed on electrode combinations and vectors, and the results of the tests can be presented to a user using the interactive representation. In an example, test results can be analyzed by a processor and optionally used to program an implantable or ambulatory medical device.Type: GrantFiled: August 4, 2011Date of Patent: September 22, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: Sunipa Saha, Kenneth N.

Patent number: 8958876Abstract: In an example of a method, the method includes testing for phrenic nerve stimulation (PS) threshold. If PS beats are detected at the pacing output level, analyzing the detected PS beats using criteria to determine if the pacing output level can be declared to be the PS threshold. If the pacing output level cannot be declared to be the PS threshold based on the analysis of the PS beat at the pacing output level, performing a PS beat confirmation procedure.
