Abstract: A wearable spatial audio device is provided. The wearable spatial audio device includes one or more audio speakers, one or more processors, and a storage machine holding instructions executable by the one or more processors. Map data is obtained for a real-world environment that includes one or more dynamic audio objects. A device-specific subset of audio tracks is obtained, and a device-specific spatialized audio mix of the device-specific subset of audio tracks that is based on the map data is obtained. An indication of a change in an environmental condition relative to one or more of the dynamic audio objects is received. The device-specific spatialized audio mix is adjusted based on the change in the environmental condition.

Abstract: Embodiments of the invention relate to electrophysiology catheters and methods of using the same. According to one embodiment, a method of treating a cardiac arrhythmia comprises forming a first lesion about a source of an electrical signal in the heart, the first lesion having an open first perimeter, and forming a second lesion about the source of the electrical signal in the heart. The second lesion has an open second perimeter and is located closer to the source of the electrical signal than the first lesion. The first lesion is discontinuous from the second lesion, and at least the first and second lesions together form a closed, at least substantially complete conduction block. According to other embodiments, catheters are provided for performing this and other methods.
