Abstract: Hair is permanently removed from a patient's skin by transcutaneously focusing high intensity acoustic energy at hair follicles and at dermal papilla regions during a telogen phase of hair growth and applying sufficient energy to destroy said follicles and said dermal papilla regions, so that hair is removed and regrowth is prevented. Typically, a region of a patient's skin is first ultrasonically imaged to show the location of a plurality of individual hair follicles and dermal papilla regions. The imaged hair follicles and dermal papilla regions are then treated using a system which automatically directs high intensity acoustic energy at each follicle and dermal papilla region.

Abstract: An ultrasound transducer includes transducer segments having a non-uniform thickness layer of relaxor ferroelectric material and coupled to a source of biasing voltage thereto. The elevational aperture is controlled by varying biasing voltage applied to the layer of relaxor ferroelectric material.

Abstract: An ultrasound transducer comprising an array of individual piezoelectric transducer elements mounted upon an improved backing comprising rigid polymeric or polymer-coated particles fused into a macroscopically rigid structure having remnant tortuous permeability to provide high acoustic attenuation and to permit fluid passage into the backing structure during fabrication.
