Abstract: An air vest for supplying successive percussive forces to a patient during a therapy session is described. The air vest includes an air bladder and at least one belt for securing the vest to a patient, with the vest adapted to engage at least a portion of the thoracic region of the patient. The vest may define an inner surface, an outer surface, and one or more extension portions for controlling movement of the inner and outer surfaces relative to each other along at least a portion of the vest. Securement and fitting of the vest to the patient may be achieved with a plurality of releasable straps.

Abstract: A method and apparatus for forming a lesion in tissue along a desired ablation path with treating a body tissue in situ (e.g., an atrial tissue of a heart to treat) atrial fibrillation include a lesion formation tool including is positioned against the heart surface. The lesion formation tool includes a guide member having a tissue-opposing surface for placement against a heart surface. An ablation member is coupled to the guide member to move in a longitudinal path relative to the guide member. The guide member includes a track. A carriage is slidably received with the track. The ablation member is secured to the carriage for movement therewith. The guide member includes a visualization component.
