  • Publication number: 20230270407
    Abstract: Medical devices, medical systems, and related methods are provided which may be used in detecting and treating anomalies in a vessel (e.g., in an artery). In one embodiment, a guidewire is provide with multiple sensors spaced apart from one another in a desired spacing. The sensors may each be configured to simultaneously detect a pressure within the vessel at their individual location within a single, common heartbeat of a patient. In one embodiment, information from the sensors may be mapped with other data or information (e.g., imaging data) to assist a healthcare professional in determining if interventional treatment is desired and, if so, what treatment may be most effective.

  • Patent number: 11602270
    Abstract: The present disclosure relates to systems and methods for generating three-dimensional tissue maps, and particularly fibrosis maps of cardiac tissue. An intravascular device includes an elongated member and a distal tip. An imaging assembly is integrated with the elongated member to enable imaging of the microstructure of tissue near the distal tip. One or more navigation electrodes are positioned at or near the distal tip. Electrical mapping and/or ablation assemblies may also be integrated with the device. Images may be characterized according to a level of fibrosis and, using the corresponding determined locations of the images, a three-dimensional map showing areas of differential fibrosis may be generated. Electrical mapping data may also be integrated with the fibrosis map to generate a composite fibrosis and voltage map.
