Problems solved by technology

[0006] However, controlling the HIFU beam to deliver spatially relatively uniform effective acoustic energy across an extended tissue volume that serves as an ideal treatment target and does not adversely affect non-target tissue can be problematic
The usual configuration of the focal volume of HIFU beam expansion presents as a "hot spot", which limits the therapeutic and / or shaping use of the beam

Embodiment Construction

[0050] figure 1 A cross-section of a perspective view of an ultrasound device 20 for treating a patient with ultrasound according to the prior art is schematically shown, the device optionally being used to lyse and remove subcutaneous fat tissue from a tissue area of ​​the patient. in figure 1 In, the device 20 is shown as being treating a tissue area 40 of the patient.

[0051] The device 20 includes a vacuum vessel 22 formed with an outlet orifice 24 and including an array of ultrasonic transducers 30 and a suitable power source (not shown) to drive the transducers. By way of example, the vacuum container 22 is an elongated cup-shaped container and includes two ultrasonic transducers 30 arranged along the bottom edge 23 of the container 22 and facing each other. Optionally, the transducer 30 is generally planar and parallel. The transducer 30 is generally covered with a matching layer 32, that is, the acoustic connection portion 32, the material of the matching layer has a th...

Abstract

A method of treating a region of tissue with ultrasound, the method comprising: generating a first ultrasound standing wave (USW) pattern at a first frequency in the region; and simultaneously generating a second USW pattern in the region spatially overlapping the first USW pattern at a second frequency different from the first frequency.

Description

[0001] Cross references to related applications [0002] This application claims the right of priority for US Provisional Patent Application No. 61 / 187,407 filed on June 16, 2010, and the entire content of the provisional application is incorporated herein by reference. Background technique [0003] Various methods are known for transmitting and connecting acoustic energy to a tissue area to perform diagnostic and / or therapeutic and / or plastic surgery on the patient's tissue. These operations are, for example, non-invasive analysis tests of blood analytes, administration of ultrasound therapy, lithotripsy for stones, etc., tissue resection, and cytolysis of fat cells for plastic removal of fat tissue. [0004] For many types of therapeutic and / or plastic acoustic applications, such as lithotripsy, tissue resection, and cell lysis as described above, sufficient acoustic energy must be delivered to the tissue area to destroy and remove the tissue in that area. Generally, acoustic ener...
