Tumescent Infusion – Tumescent fluid containing small gas bubbles 5 to 10 microns in size is infused throughout targeted fat tissue. Tight junctions between cells within blood vessel walls and connective tissues prevent gas bubbles from interspersing among and affecting these tissues.1

Cavitation – Acoustic energy delivered through an ultrasonic probe results in rapid formation and collapse of bubbles in the tumescent fluid, dislodging clusters of intact fat cells with minimal (if any) impact on vessels, nerves, and other tissues.2-4,6
Acoustic streaming – Grooves on ultrasonic probe generate strong localized fluid forces, further separating dislodged fat clusters into smaller clumps, which can be used during fat grafting procedures.1,2,4-6

Fat Removal - The design of the small-diameter cannula minimizes trauma to vessels, nerves and the fibrous tissue matrix when inserted to suction out the mixed fat cell and tumescent fluid emulsion (compared to second-generation cannulas).

Tissue Remodeling - Adipose tissue removal during liposuction creates a space for retraction to occur. Post-procedure skin retraction is optimized when the superficial fatty layer is “thinned” with minimal trauma to tissues and the elastic subcutaneous connective tissue matrix is preserved. This allows the skin to naturally retract and re-drape to the underlying frame during the healing process.1
