Abstract
Apparatus is provided for ablating cardiac tissue of a subject. The apparatus comprises an inflatable element, configured to be transthoracically placed within a pericardial region of the subject and a reflection-facilitation element, configured to deliver a fluid to the pericardial region, such that a portion of the fluid is disposed within the inflatable element, and another portion of the fluid is disposed outside of the inflatable element and inside the pericardial region. The apparatus additionally comprises at least one ultrasound transducer, configured to be transcatheterally placed in a heart chamber of the subject, and to apply ultrasound energy such that at least a portion of the applied energy is reflected by the fluid. Other embodiments are also described.
