Systems and method for ultra-high frequency ultrasound treatment
First Claim
1. A method for providing treatment to a patient having a melanoma or a non-melanoma skin disorder, the method comprising:
- coupling an ultrasound transducer to a skin surface of a patient;
emitting energy from the ultrasound transducer in a frequency range from about 10 MHz to about 30 MHz or from about 20 MHz to about 500 MHz into a superficial region of interest below the skin surface of the patient, the superficial region of interest consisting of a subcutaneous layer of skin,thereby ablating tissue in a portion of the region of interest,thereby creating a lesion in the tissue at a depth in a range of 0.1 μ
m to 100 μ
m below the skin surface, the lesion treating the melanoma or the non-melanoma skin disorder; and
sparing tissue at the depth of greater than 100 μ
m below the skin surface from damage from the ablating tissue.

Abstract
A non-invasive ultra-high frequency ultrasound treatment method and system are provided. An exemplary method and system comprise a high-frequency ultrasound transducer system configured for providing ultrasound treatment to a patient such that the superficial and/or subcutaneous regions of the patient can be treated. An exemplary high-frequency ultrasound transducer system comprises a control system and a transducer configured to provide treatment to the superficial and/or subcutaneous regions of interest. The high-frequency ultrasound transducer may be configured to operate at higher frequencies and controlled power levels to provide treatment to the superficial and/or subcutaneous regions of interest. For example, higher frequencies within the range from approximately 20 MHz to 500 MHz or more may be utilized.

10. A method for treating a melanoma in a patient'"'"'s skin, the method comprising:
-
coupling an ultrasound transducer to a skin surface of the patient; emitting energy from the ultrasound transducer within a frequency range from about 10 MHz to about 30 MHz into a region of interest comprising superficial tissue in at a depth in a range of 0.1 μ
m to 100 μ
m below the skin surface;ablating superficial tissue in a portion of the region of interest; creating a lesion in the superficial tissue; treating a melanoma in the region of interest; and leaving tissue below the region of interest unaffected. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method for providing ultrasound treatment to a patient having a melanoma or a non-melanoma skin disorder, the method comprising:
-
a) operating a transducer to emit acoustical energy within a frequency range from about 10 MHz to 30 MHz or from about 20 MHz to about 500 MHz; b) coupling the transducer to a region of interest consisting of a superficial region and a subcutaneous region; c) focusing a first acoustical energy to a first depth in the region of interest, thereby ablating a portion of superficial tissue in the superficial region, thereby creating a first lesion in the superficial tissue; d) focusing a second acoustical energy to a second depth in the region of interest, thereby ablating a portion of subcutaneous tissue in the subcutaneous region, thereby creating a second lesion in the subcutaneous tissue; and e) leaving tissue below the region of interest unaffected, wherein the focusing of step c), step d), or steps c) and d) treats the melanoma or the non-melanoma skin disorder in at least a portion of the region of interest. - View Dependent Claims (17, 18, 19, 20)
