Abstract

Electromedical apparatus is employed together with local topically applied drugs and general medical management program to non-invasively, non-traumatically, reduce in volume without fat cell death, specific local accumulations of stored triacylglyceride by localizing (e.g., focusing) radiant energy and/or localized lipolysis augmentation methods, thereby accelerating local fat tissue lipolysis reaction rates. The radiant energy includes, localized radio frequency, microwave or ultrasound energy, which impinges upon the fat cells to be reduced in volume but not killed or eliminated. Fat cell size reduction occurs through the mechanism of accelerated lipolysis rate which is a function of local cell temperature elevation and local fat cell lipolysis rate augmentation by local lipolytic drug delivery.

Claims

1. A method of reducing adipose cell volume in a human patient by non-invasively, non-destructively, and atraumatically increasing a lipolysis rate at specific accumulations of subcutaneous adipose tissue, comprising the steps of:

selecting a desired work site in the patient'"'"'s subcutaneous adipose tissue layer containing healthy adipose cells to be reduced in volume;

focusing radiant energy on said work site to raise the temperature thereof to between 40.0°

to 41.5°

C.; and

maintaining the radiant energy focused on said work site to increase the lipolysis rate thereof sufficiently to cause release of free fatty acids, thereby reducing the volume of the adipose cells.

2. A method as claimed in claim 1, wherein said method includes a preliminary step of determining a schedule of treatment for said patient.

3. A method as claimed in claim 1 wherein said method includes an initial step of:

identifying a number of work sites for body contour modification by assessing overall health, fitness, and suitability of the patient for any local or general medical intervention and by performing baseline medical, laboratory, biometric, and contour measurements;

said selecting step includes selecting one of the work sites as the desired work site,

determining whether to utilize topical lipolytic augmentation agents at said desired work site in conjunction with radiant energy modalities, including ultrasonic, radio frequency and microwave, and selecting and applying a topical lipolytic agent to said work site prior to said focusing step and selecting a conjunctive source of said radiant energy;

determining an overall treatment program and schedule by projecting a number of encounters necessary to achieve satisfactory site-specific body contour modification by the reduction of local subcutaneous adipose tissue volume at said desired work site, and establishing a medical management program which achieves a calorie negative metabolic state.

4. A method as claimed in claim 1, wherein said method further comprises the step of employing an imaging apparatus for viewing the changes in volume of the adipose cells.

5. A method as claimed in claim 1, including supplying said radiant energy from an ultrasonic source.

6. A method as claimed in claim 1, including supplying said radiant energy from a radio frequency source.

7. A method as claimed in claim 1, including supplying said radiant energy from a microwave source.

8. A method as claimed in claim 1, including focusing said radiant energy on the work site using a field-conjugate acoustic lens having a configuration specific for the work site.

9. A method as claimed in claim 1, including focusing said radiant energy on the work site using a combination of a concave lens and a field-conjugate acoustic lens, wherein the field-conjugate acoustic lens has a configuration specific for the work site.

10. A method as claimed in claim 1, including directing said radiant energy on the work site through a temperature-controlled water bolus, thereby maintaining a predetermined temperature at a skin surface directly over the work site.

11. A method as claimed in claim 10, including controlling said focussing of radiant energy on the work site by controlling the temperature of the water bolus.

12. A method as claimed in claim 1, wherein said method further includes topically applying at least one adipose tissue lipolysis augmentation agent to a skin surface directly over the work site to enhance the local radiant energy effects.

13. The method as claimed in claim 12, including directing said adipose tissue lipolysis augmentation agent on said work site by phonophoresis.

14. A method as claimed in claim 1, including heating said work site with said radiant energy for up to 29 minutes.

15. A method as claimed in claim 1, including heating said work site with said radiant energy for between 20 and 29 minutes.

16. A method of reducing adipose cell volume in a human patient by non-invasively, non-destructively, and atraumatically increasing a lipolysis rate at specific accumulations of subcutaneous adipose tissue, comprising the steps of:

determining a schedule of treatment and identifying a number of work sites for body contour modification for said patient by assessing overall health, fitness, and suitability of the patient for any local or general medical intervention and by performing baseline medical, laboratory, biometric, and contour measurements;

determining whether to utilize topical lipolytic augmentation agents in conjunction with radiant energy modalities, including ultrasonic, radio frequency and microwave;

selecting a topical lipolysis augmentation agent and a conjunctive source of a radiant energy;

determining an overall treatment program and schedule by projecting a number of encounters necessary to achieve satisfactory site-specific body contour modification by a reduction of local subcutaneous adipose tissue volume, and establishing a medical management program which achieves a calorie negative metabolic state;

selecting a desired work site from said number of work sites in the patient'"'"'s subcutaneous adipose tissue layer containing healthy adipose cells to be reduced in volume;

topically applying said lipolysis augmentation agent to a skin surface directly over the work site;

focusing said radiant energy through conjugate field lenses of a specific configuration adapted for said work site and through a temperature-controlled water bolus, said radiant energy focusing on subcutaneous adipose tissues in said work site to raise the temperature thereof to between 40.0°

to 41.5°

C. said water bolus maintaining the skin surface at the work site at a pre-determined temperature; and

maintaining the radiant energy focused on said work site for up to 29 minutes, increasing said lipolysis rate thereof sufficiently to cause release of free fatty acids, thereby reducing the volume of the adipose cells;

employing an imaging apparatus for viewing the changes in volume of the adipose cells.

17. A method as claimed in claim 16, including supplying said radiant energy from an ultrasonic source.

18. A method as claimed in claim 16, including supplying said radiant energy from a radio frequency source.

19. A method as claimed in claim 16, including supplying said radiant energy from a microwave source.
