Solution Overview
Problem
Current non-invasive methods for removing subcutaneous fat, such as percutaneous energy delivery, are not particularly effective in achieving significant adipose tissue reduction while minimizing invasive procedures.
Innovation Solution
A radiofrequency energy delivery device with an open-ended coaxial design, where an outer conductor and inner conductor generate an electromagnetic field that crosses tissue layers orthogonally, causing localized heating and adipocyte lysis or destruction, is used to treat adipose tissue layers effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If non-invasive percutaneous energy delivery methods are used to remove subcutaneous fat, then invasiveness is minimized, but treatment effectiveness is insufficient
Solution Approach 1:
The patent applies local quality by directing electromagnetic energy specifically to the adipose tissue layer through controlled field geometry. The electromagnetic field is configured to concentrate energy deposition in the subcutaneous fat layer while sparing the overlying skin and underlying muscle, achieving localized treatment effectiveness without invasive procedures.
Solution Approach 2:
The patent utilizes parameter changes by adjusting electromagnetic field frequency, intensity, and duration to optimize fat cell destruction. By varying these parameters, the treatment achieves effective adipose tissue removal while maintaining safety margins for surrounding tissues, resolving the contradiction between non-invasiveness and effectiveness.
2Device complexity
If electromagnetic field lines extend parallel to tissue layers, then energy delivery is simplified, but heat dissipation in adipose tissue is reduced
Solution Approach 1:
The patent applies dimensionality change by transitioning from parallel field line orientation to orthogonal field line orientation relative to tissue layers. This orthogonal configuration creates a new dimension of energy delivery that maximizes current flow through the adipose tissue perpendicular to the skin surface, significantly enhancing heat dissipation and treatment effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device achieves efficient adipose tissue reduction by concentrating heat dissipation in adipose layers, reducing fat through apoptosis, and improving the appearance of cellulite-afflicted skin by disrupting interlobular septa, thereby addressing the ineffectiveness of existing non-invasive methods.
Implementation Method 1
the outer conductor and the inner conductor, arranged and configured so as to form the open-ended coaxial line, generate an electromagnetic field with lines of force extending from a front surface of the inner conductor to a front surface of the outer conductor
Implementation Method 2
an electric field propagates in the tissues below the area where the delivery device has been applied to the skin... causing greater heat dissipation and therefore greater heating in the tissues having more resistivity. These tissues are indeed the adipose layers
Implementation Method 3
causing adipocytes lysis, i.e. the destruction of the cell membranes and therefore the liquefaction of adipocytes
