Abstract: A computer-implemented method for generating and displaying a graphical user interface (GUI) is disclosed. The method includes displaying, via the GUI, a real-time video received from a camera disposed within an ablation catheter. The method further includes displaying, via the GUI, a graphical representation of a plurality of electrodes of the ablation catheter.

Abstract: Diagnostic and therapeutic medical devices and methods that include an elongate shaft, a balloon, a plurality of electrodes carried by the balloon, and electronics to electrically connect the electrodes to a proximal end of the shaft. The devices can include a visualization system within the balloon.

Abstract: Visualization and ablation systems and catheters. The systems can capture a plurality of different 2D images of the patient's anatomy adjacent an expandable member, each of which visualizes at least one part of the patient that is in contact with the expandable membrane, tag each of the plurality of different 2D images with information indicative of the position and orientation of a locational element when each of the plurality of different 2D images was captured, create a patient map, wherein creating the patient map comprises placing each of the plurality of different 2D images at the corresponding tagged position and orientation into a 3 space, and display the patient map.

Abstract: An ablation catheter includes an elongate shaft and an inflatable ablation member. The inflatable ablation member includes a flexible circuit with a conductor in electrical communication with an ablation electrode. The flexible circuit is disposed outside of and carried by an outer surface of an inflatable balloon. The inflatable ablation member includes an ultrasound monitoring member configured for use in monitoring at least one aspect of tissue ablation with the ablation electrode.

Abstract: Cardiac ablation catheters and methods of use. Catheters that include an expandable membrane, an imaging member disposed within the expandable membrane, the imaging member having a field of view, a light source disposed within the expandable member adapted to deliver light towards the field of view of the imaging member, and an electrode comprising an outer conductive layer and inner light absorbing layer disposed between the electrode and the expandable membrane, the inner light absorbing layer adapted to absorb light from the light source and thereby reduce reflection of the light from the outer conductive electrode.

Abstract: An inflatable assembly that can be positioned within a patient, including an expandable membrane, an imaging member disposed within the expandable membrane, a diffuse reflector secured relative to the expandable membrane, and a light source disposed within the expandable membrane and positioned to direct light towards the diffuse reflector such that diffuse reflection of the light is directed towards a field of view of the imaging member.

Abstract: Queries are evaluated against received event information and notifications that events specified in the queries have occurred are generated by following the steps of recording the number of queries; receiving an item of event information; comparing the received item of event information with the queries; and generating a notification if the item of event information matches the query. Normally, a series of items of event information will be received and these are compared sequentially with the queries. Each query can be arbitrarily complex comprising a plurality of sub-queries, each requiring a different item or items of event information to be matched.
