Publication number: 20230011001Abstract: A system and method are provided for a navigational feedback to a catheter during an arrhythmia ablation procedure. A set of electrocardiogram (ECG) signals of a patient's arrhythmia is recorded that correspond to an unknown target location to be ablated by the catheter. During the ablation procedure, pacing locations and ECG signals corresponding to the pacing locations are collected to derive a mathematical operator that maps a 12-dimensional displacement vector in the ECG space to a 3-dimensional (3D) vector in a physical space. This 3D vector corresponds to a direction and a distance that the catheter needs to be moved in order to reach the target location of the arrhythmia.Type: ApplicationFiled: December 2, 2020Publication date: January 12, 2023Inventors: Konstantinos N. ARONIS, Ronald D. BERGER, Natalia A. TRAYANOVA, Shijie ZHOU, Harikrishna TANDRI

Patent number: 10617599Abstract: A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actual depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression is then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (such as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.Type: GrantFiled: December 13, 2016Date of Patent: April 14, 2020Assignee: ZOLL Medical CorporationInventors: James A Palazzolo, Darren R Sherman, Ronald D Berger, Henry R Halperin

Patent number: 8123742Abstract: Featured is a catheter device for ablating tissue that includes an elongated body member having a distal portion and a deflection mechanism operably coupled to the distal portion so as to cause the distal portion to deflect with respect to a longitudinal axis of the elongated body member. Such a catheter device also includes a guide member and a guiding mechanism that is coupled to the elongated body member and is configured so as to guide the guide member. The guiding mechanism includes an exit portion from which the guide member exits during deployment. The exit portion is disposed with respect to the distal portion end so the distal portion deflects from and with respect to the guide member as well as rotating about the guide member. Also featured are systems and methods related thereto.Type: GrantFiled: October 20, 2004Date of Patent: February 28, 2012Assignee: The Johns Hopkins UniversityInventor: Ronald D. Berger
