Abstract

Abstract A method of removing animal fatty tissue includes inserting an ultrasonic aspirating probe (10) into the body in the area of the fatty tissue between the flesh, including blood vessels and arteries, and the muscle. The probe (10) 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 (10) to melt. The probe (10) 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: 7
Claim 1
Independent Claim 99 words
A method of removing animal fatty tissue from a patient in vivo comprising the steps of: inserting an aspirating probe (10) into the body in an area between the flesh and the muscle in the area of said fatty tissue; ultrasonically vibrating the probe (10) at substantially high frequencies and low amplitudes; irrigating the area surrounding the probe; emulsifying said fatty tissue; aspirating the emulsified fatty tissue by applying suction; the method being characterised by the steps of: creating localised tissue separation; creating localized frictional heat; and melting at least some of some fatty tissue by said localized heat.
Claim 2
Independent Claim 99 words
A method of removing animal fatty tissue from a patient in vivo comprising the steps of: inserting an aspirating probe (10) into the body in an area between the flesh and the muscle in the area of said fatty tissue; ultrasonically vibrating the probe (10) at substantially high frequencies and low amplitudes; irrigating the area surrounding the probe; emulsifying said fatty tissue; aspirating the emulsified fatty tissue by applying suction; the method being characterised by the steps of: creating localised tissue separation; creating localized frictional heat; and melting at least some of some fatty tissue by said localized heat.
Claim 3
Dependent Claim 29 words
A method as in Claim 1, characterised in that adjustment is provided for the amplitude any frequency of the ultrasonic vibrations to vary the intensity of the localized heat.
Claim 4
Dependent Claim 27 words
A method as in Claim 1 or Claim 2, characterised in that placement of the probe (10) is in the area substantialy below the patient's blood vessels.
Claim 5
Independent Claim 37 words
A method as in any one of Claims 1 or 3, characterised in that there is provided forcusing of said heat adjacent a probe tip (14) having a rounded, closed end and at least one entry orifice.
Claim 6
Independent Claim 35 words
A method as in any one of Claims 1 or 3, characterised in that there is provided forcusing of said heat adjacent a probe tip (16) having a rounded, partially closed and partially open end.
Claim 7
Independent Claim 35 words
A method as in any one of Claims 1 to 3, characterised in that there is provided focusing of said heat adjacent a probe tip (18) having a rounded, closed end and multiple in-line orifices
