A medical procedure utilizes a high-intensity focused ultrasound instrument having an applicator surface, a liquid-containing bolus or expandable chamber acting as a heat sink, and a source of ultrasonic vibrations, the applicator surface being a surface of a flexible wall of the bolus, the source of ultrasonic vibrations being in operative contact with the bolus. The applicator surface is placed in contact with an organ surface of a patient, the source is energized to produce ultrasonic vibrations focused at a predetermined focal region inside the organ, and a temperature of liquid in the bolus is controlled while the applicator surface is in contact with the organ surface to control temperature elevation in tissues of the organ between the focal region and the organ surface to necrose the tissues to within a desired distance from the organ surface.

Apparatus & methods for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue. Various devices, e.g., stops, spring members, fuses, strain gauges, etc., can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e.g., varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.
