Abstract
Apparatus comprising an ultrasound ablation system, which comprises a reflection-facilitation element, configured to be placed at an extramyocardial site of a subject, and to provide an extramyocardial reflective region; and an ultrasound tool, which comprises at least one ultrasound transducer configured to be positioned within a heart chamber of the subject. The ultrasound transducer is configured to ablate myocardial tissue by applying ultrasound energy to the myocardial tissue such that at least a portion of the transmitted energy is reflected by the reflective region onto the myocardial tissue. Other embodiments are also described.

Apparatus comprising an ultrasound ablation system, which comprises:
- a reflection-facilitation element, configured to be placed at a far side of a tissue of a subject, and to provide a reflective region;
- and
- an ultrasound tool, which comprises at least one ultrasound transducer configured to be positioned at a near side of the tissue of the subject, and to ablate the tissue by applying ultrasound energy to the near side of the tissue such that at least a portion of the transmitted energy is reflected by the reflective region onto the tissue.
Apparatus comprising an ultrasound ablation system, which comprises:
- a reflection-facilitation element, configured to be placed within a heart chamber of a subject, and to provide an intracardiac reflective region;
- and
- an ultrasound tool, which comprises at least one ultrasound transducer configured to be positioned at an extramyocardial site of the subject, and to ablate myocardial tissue by applying ultrasound energy to the myocardial tissue such that at least a portion of the transmitted energy is reflected by the reflective region onto the myocardial tissue.
A method comprising:
- advancing, into a heart chamber of a subject, an ultrasound tool that includes at least one ultrasound transducer;
- providing a reflective region at an extramyocardial site of the subject;
- and
- activating the ultrasound transducer to ablate myocardial tissue by applying ultrasound energy to the myocardial tissue such that at least a portion of the transmitted energy is reflected by the reflective region onto the myocardial tissue of the subject.
