Abstract

Abstract A method of removing human body fatty tissue includes inserting an ultrasonic aspirating probe into the body in the area of the fatty tissue between the flesh, including blood vessels and arteries, and the muscle. The probe is ultrasonically vibrated at high frequencies and low amplitudes creating localized tissue separation and frictional heat. This heat causes the fatty tissue surrounding the probe to melt. The probe is specially adapted to provide a localized flow of irrigating fluid. This fluid serves to emulsify the melted and separated fat. The emulsified fat is then aspirated through specially designed orifices from the body using suction.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 105 words
A method of removing animal fatty tissue from a patient in vivo comprising the steps of: inserting an aspirating probe into the body in an area between the flesh and the muscle in the area of the fatty tissue; ultrasonically vibrating said probe at substantially high frequencies and low amplitudes, creating localized tissue separation and frictional heat; melting at least some of said fatty tissue by said localized heat, so as to provide more efficient removal of said fatty tissue; irrigating the area surrounding the probe; emulsifying said fatty tissue; and aspirating the emulsified fatty tissue by applying suction, whereby a slimmer profile is provided.
Claim 2
Independent Claim 105 words
A method of removing animal fatty tissue from a patient in vivo comprising the steps of: inserting an aspirating probe into the body in an area between the flesh and the muscle in the area of the fatty tissue; ultrasonically vibrating said probe at substantially high frequencies and low amplitudes, creating localized tissue separation and frictional heat; melting at least some of said fatty tissue by said localized heat, so as to provide more efficient removal of said fatty tissue; irrigating the area surrounding the probe; emulsifying said fatty tissue; and aspirating the emulsified fatty tissue by applying suction, whereby a slimmer profile is provided.
Claim 3
Dependent Claim 26 words
The method of claim 1 wherein adjustment is provided to the amplitude and frequency of said ultrasonic vibrations to vary the intensity of said localized heat.
Claim 4
Dependent Claim 20 words
The method of claim 1 wherein placement of said probe is in the area substantially below the patient's blood vessels.
Claim 5
Dependent Claim 27 words
The method of claim 1 wherein is provided focusing of said heat adjacent a probe tip having a rounded, closed end and at least one entry orifice.
Claim 6
Dependent Claim 25 words
The method of claim 1 wherein is provided focusing of said heat adjacent a probe tip having a rounded, partially closed and partially open end.
Claim 7
Dependent Claim 25 words
The method of claim 1 wherein is provided focusing of said heat adjacent the probe tip having a rounded, closed end and multiple in-line orifices.
Claim 8
Dependent Claim 21 words
The method of claim 1 including the step of protecting delicate tissue by thermally insulating a portion of said probe tip.
