Abstract: Provided herein are systems, devices, and methods for treating tissue of a patient. The system includes a first energy delivery device having a first energy delivery element to be positioned proximate target tissue of the patient, a second energy delivery element, an energy delivery console to provide energy between the first energy delivery element and the second energy delivery element, and a user interface having a display for providing information to a user. The energy provided by the energy delivery console creates one or more electric fields within an energy delivery volume proximate the first energy delivery element, and at least one electric field within the energy delivery volume is sufficient to irreversibly electroporate target tissue within the energy delivery volume.

Abstract: A cardiac information dynamic display system comprises one or more electrodes and a cardiac information console. The one or more electrodes record sets of electric potential data representing cardiac activity at a plurality of time intervals. The cardiac information console includes a signal processor and a user interface module. The signal processor calculates sets of cardiac activity data at the plurality of time intervals using the recorded sets of electric potential data. The cardiac activity data is associated with surface locations of one or more cardiac chambers. The user interface module displays information related to the cardiac activity data. The information is presented relative to a graphical representation of surfaces of the one or more cardiac chambers.

Abstract: Provided herein are systems, devices, and methods for performing a medical procedure on a patient. The system comprises an ablation catheter comprising a shaft, at least one therapeutic element positioned on the shaft, and one or more tissue-contact sensing components configured to provide a contact signal related to the level of contact between the at least one therapeutic element and tissue. The system further comprises: an energy delivery unit configured to deliver ablative energy to the at least one therapeutic element to create a lesion in target tissue, and to provide an energy delivery data; a force module configured to receive the contact signal and provide contact data; and a processing unit configured to determine an ablation index based on both the energy delivery data and the contact data. The ablation index can represent the status of the lesion being created.

Abstract: Provided herein are systems for modeling a patients cardiac electrical activity data, including at least one diagnostic catheter for insertion into the heart of the patient and a processing unit. The at least one diagnostic catheter includes at least one recording element to record patient data over multiple cardiac cycles. The patient data includes biopotential data and localization data of the at least one recording element. The processing unit includes a clustering routine that: receives the recorded patient data; segments the recorded patient data by cardiac cycle to produce segmented patient data; groups the segments based on one or more characteristics of the segments to produce segmented data groups; and combines the segmented patient data within each segmented data group to produce one or more composite recordings. The systems create one or more models of cardiac electrical activity of the patient based on the one or more composite recordings.
