Lipo Harvesting Cannula Careful harvesting is crucial to ensure successful and longer lasting autologous fat augmentation in the vocal folds. In addition to a low level of negative pressure when harvesting, the special shape, arrangement and cut of the suction holes ensure safe harvesting of the fat cells. Once harvested, the cannula tube provides the fat cells with enough space, so that they can be drawn up into the syringe, without higher pressure. Properties • Atraumatic beveled suction holes on the cannula tip • Low suction pressure, thanks to manually build-up pressure • Special arrangement...

Application and Handling of the VoiceInject®-System Step 1: Fat extraction • Sampling of homogeneous fat tissue with extraction system Step 2: Preparation of the extracted fat tissue • Use centrifuge to separate harvested tissue (max 3000 rpm for 3 minutes). Drain blood cells, serum, free fatty acids and cell debris and keep the fat tissue Step 3: Transfer fat tissue • Transfer fat tissue into 1 ml syringes using the connector Step 4: Micro re-injection • Inject fat tissue into the vocal folds as needed SPIGGLE & THEIS | VoiceInj
