The high frequency vibration of VASER Ultrasonic Probes causes the fat cells to break apart and emulsify into the infusion fluid (most fat cells remain viable).
Emulsified fat is more easily removed via specially designed VentX ® Suction Cannulae. VentX Never clogs - has ports in the handle Maximum pressure is never exceeded
ultrasound does not cavitate fat cells , it cavitates microbubbles in the tumescent fluid, infiltrated among the fat cells.
University of Stampford study shows that almost 80% of cells are still intact after treatment.
A recent study exposed bovine fat infused with saline to laser energy (25W, 980 nm) and to VASER ultrasound energy (100% amplitude, 3.7mm, 2-ring probe) LASER: temperature in fat rose above the tissue damage threshold in less than 50 milliseconds; temperatures reached the boiling point within 0.1 seconds. VASER: temperature never rose more than 9ºC. Further, the acoustic streaming from the VASER kept the fluid well mixed, distributing the thermal energy; because the laser has no comparable mechanism, the heat does not dissipate
Fast recovery is highly dependant on operator experience Pain generally the same for both groups in my experience Reduce need for re treatment is operator dependant Biggest difference Laser “Flogging the donkey” whereas VASER “Holding back the racehorse”
