Abstract: Disclosed herein are system, method, and computer-readable medium aspects for assessing ablation lesions in realtime. An aspect operates by receiving a first optical measurement data from a first catheter optical port, assigning the first optical measurement data to a first available processing core in a processing unit in order to identify an optical property at a first location of a lesion, and generating a first graphical representation from the optical property at the first location of the lesion. After a predetermined time, the aspect continues to operate by repeating the receiving, assigning, and generating operations for a second optical measurement data using a second available processing core in order to generate a second graphical representation from the optical property at a second location of the lesion. The aspect concludes by displaying the first graphical representation and the second graphical representation on a user interface at a predefined interval.

Abstract: Disclosed herein are system, method, and computer-readable medium aspects for improving the accuracy of an ablation model through synchronization. An aspect operates by activating a catheter energy source, acquiring a catheter energy signal from the catheter energy source, assigning an activation time stamp and deactivation time stamp to the catheter energy signal, and determining a time of ablation based on a time period between the activation time stamp and deactivation time stamp. The aspect continues to operate by acquiring an optical measurement signal from a catheter optical port, assigning an input time stamp and switching time stamp to the optical measurement signal, and processing the optical measurement signal in order to acquire a denaturation result. The aspect concludes by synchronizing the time of ablation and the denaturation result using the time stamps in order to generate a synchronized model and generating an estimated lesion depth from the synchronized model.

Abstract: Described herein are systems, methods for detecting gaps between lesions formed in tissue during ablation. A system includes a catheter that has proximal section, a distal section, and a shaft coupled between the proximal section and the distal section. A plurality of optical fibers are located within the catheter and are coupled to a computing device. The computing device includes a memory and a processor configured to receive, from the optical fibers, optical measurement data of a portion of tissue during or after an ablation, identify one or more optical properties of the portion of tissue by analyzing the optical measurement data, and detect a presence or an absence of a gap between one or more lesions formed in the portion of tissue based on the one or more optical properties.

Abstract: Described herein is a system including a catheter, an optical circuit, a pulsed field ablation energy source, and a processing device. The catheter includes a proximal section, a distal section, and a shaft coupled between the proximal section and the distal section. The optical circuit is configured to transport light at least partially from the proximal section to the distal section and back. The pulsed field ablation energy source is coupled to the catheter and configured to transmit pulsed electrical signals to a tissue sample. The processing device is configured to analyze one or more optical signals received from the optical circuit to determine changes in polarization or phase retardation of light reflected or scattered by the tissue sample, and determine changes in a birefringence of the tissue sample based on the changes in polarization or phase retardation.
