Our Solution
Our Solution

Engineered for efficiency and precision, Sayenza’s automated, multifunctional device processes fat in under 15 minutes. Simultaneously, it creates a potent, ready-to-use therapeutic, for reinjection at the point of care.



Traditional fat processing can take up to 2 hours, reducing clinical efficiency.

Multistep/Manual Input

Manual, multistep procedures lead to inconsistent outcomes, compromising patient results.


Multiple manual steps increase the chance of contamination, posing potential health risks.


Labor-intensive processes divert surgeons' attention from primary patient care, impacting overall treatment quality.
