US Patent:

7815633, Oct 19, 2010

Filed:

Jun 4, 2008

Appl. No.:

12/156870

Inventors:

Claudio I. Zanelli - Menlo Park CA, US
Samuel M. Howard - Mountain View CA, US

International Classification:

A61B 18/04

US Classification:

606 27, 606 28

Abstract:

Hair is permanently removed from a patient's skin by transcutaneously focusing high intensity acoustic energy at a hair follicle and applying sufficient energy to destroy the follicle, whereby hair is removed and regrowth is prevented. Typically, a region of a patient's skin would be ultrasonically imaged to show the location of a plurality of individual hair follicles. The individual imaged hair follicles are then treated using a system which automatically directs the high intensity acoustic energy at each follicle.

Appl. No.:

12/800299

Inventors:

Claudio I. Zanelli - Menlo Park CA, US
Samuel M. Howard - Mountain View CA, US

International Classification:

A61B 18/04

US Classification:

606 27, 606 28

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.

US Patent:

56572956, Aug 12, 1997

Filed:

Nov 29, 1995

Appl. No.:

8/564424

Inventors:

Samuel M. Howard - Mountain View CA

Assignee:

Acuson Corporation - Mountain View CA

International Classification:

H04R 144

US Classification:

367140

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.

Michael H. Ikeda - San Jose CA

Assignee:

Acuson Corporation - Mountain View CA

International Classification:

A61B 800

US Classification:

12866203

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.

Appl. No.:

8/482147

Inventors:

John A. Hossack - Palo Alto CA
Samuel Moss Howard - Mountain View CA

Assignee:

Acuson Corporation - Mountain View CA

International Classification:

A61B 800

US Classification:

12866203

Abstract:

An ultrasound transducer and the method for the manufacture thereof which is designed to reduce the generation of elevational sidelobes. At least one kerf is formed in each end region of a body of piezoelectric material. The kerfs define therebetween a center region formed solely of piezoelectric material. The kerfs are filled with a second material.
