    Abstract: Described herein are devices and methods for performing merged optical tissue evaluation and laser ablation with a catheter system that includes a processing device and a catheter with proximal and distal sections with a plurality of optical ports that are configured to transmit beams of exposure radiation to a sample, receive one or beams of scattered radiation, and transmit laser ablation energy such that a portion of the sample is ablated. The processing device includes a first optical source configured to generate a source beam of exposure radiation and a second optical source configured to generate the laser ablation energy. The catheter system further includes one or more multiplexers that direct the beams of exposure radiation to the plurality of optical ports, combine the one or more beams of scattered radiation, and direct the laser ablation energy to at least one optical port of the plurality of optical ports.

    Abstract: Described herein are devices and methods for performing ablation using ablation catheters with one or more patterned and textured active areas. An ablation catheter includes a proximal section, a distal section, and a sheath coupled between the distal section and the proximal section. The distal section includes an active area with a patterned, textured surface that is configured to apply radiofrequency (RF) energy, cryogenic cooling, or laser energy output to a portion of target tissue, such that the portion of target tissue is ablated. The patterned, textured surface of the active area is configured to maintain contact between the target tissue and the active area.

    Abstract: Embodiments for crossing an occlusion by controlling a guide with the aid of optical coherence tomography (OCT) data are described. Embodiments include transmitting one or more beams of radiation via one or more waveguides on a flexible substrate within a guide wire. One or more beams of scattered or reflected radiation may be received from a sample via one or more waveguides. Depth-resolved optical data of the sample may be generated based on the received beams of scattered or reflected radiation. The depth-resolved data may be used for determining at least one of a distance between the guide wire and a wall of the artery and a distance between the guide wire and an occlusion within the artery. A position of the guide wire within the artery may then be controlled based on the determined distance or distances.

    Abstract: A system for optical coherence tomography using multiple interferometers presented. The interferometry system includes a source configured to generate a variable wavelength light beam. A first splitter is configured to split the variable wavelength light beam to at least a first light beam and a second light beam. A first delay element is configured to delay the first light beam by a first time delay. A second delay element is configured to delay the second light beam by a second time delay, such that the delayed first light beam and the delayed second light beam are out of coherence with each other. A first interferometer is configured to receive the delayed first light beam as an input. A second interferometer is configured to receive the delayed second light beam as an input.

    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.
