Abstract
Abstract Electromedical apparatus is employed to non-invasively remove adipose tissue from the body by causing necrosis thereof by localizing (e.g., focusing) radiant energy. The radiant energy may be of any suitable kind, for example, localized radio frequency, microwave or ultrasound energy, which is impinged upon the cells to be eliminated. Cell destruction occurs through a mechanism such as, e.g., heating or mechanical disruption beyond a level which the adipose tissue can survive.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
86 words
A method of controlling obesity in a human subject by non-invasively eliminating excess healthy adipose tissue from a subcutaneous adipose tissue layer of the human subject, comprising the steps of: determining a desired work site in the subject's subcutaneous adipose tissue layer containing excess healthy adipose cells to be eliminated; focusing radiant energy on said cells to raise the temperature thereof; and maintaining the energy focused on said work site until the excess healthy adipose tissue to be eliminated absorbs sufficient energy to cause cell destruction.
Claim 2
Independent Claim
86 words
A method of controlling obesity in a human subject by non-invasively eliminating excess healthy adipose tissue from a subcutaneous adipose tissue layer of the human subject, comprising the steps of: determining a desired work site in the subject's subcutaneous adipose tissue layer containing excess healthy adipose cells to be eliminated; focusing radiant energy on said cells to raise the temperature thereof; and maintaining the energy focused on said work site until the excess healthy adipose tissue to be eliminated absorbs sufficient energy to cause cell destruction.
Claim 3
Dependent Claim
15 words
A method of claim 1, further comprising employing imaging apparatus for viewing said tissue destruction.
Claim 4
Dependent Claim
21 words
A method as in claim 1, further comprising employing imaging apparatus for determining the quantity of adipose tissue to be destroyed.
Claim 5
Dependent Claim
16 words
A method as in claim 1, wherein said energy is supplied from an ultrasonic energy source
Claim 6
Dependent Claim
16 words
A method as in claim 1, wherein said energy is supplied from a radio frequency energy
Claim 7
Dependent Claim
16 words
A method as in claim 1, wherein said energy is supplied from a microwave energy source.
Claim 8
Dependent Claim
21 words
A method as in claim 1, wherein the temperature at said work site is raised to substantially at least 43.3°-44.4° C.
Claim 9
Dependent Claim
21 words
A method as in claim 1, wherein said temperature at said work site is maintained for substantially at least 30-40 minutes.
Claim 10
Dependent Claim
21 words
A method as in claim 8, wherein the temperature at said work site is raised to substantially at least 43.3°-44.4° C.
Claim 11
Dependent Claim
16 words
A method as in claim 1, wherein said energy causes cell destruction by causing cell necrosis.
Claim 12
Dependent Claim
20 words
A method as in claim 1, wherein said work site is raised to a temperature sufficient to destroy adipose cells.
