Beyond the core function, the Cell Select Harvesting Cannula is typically manufactured from medical-grade, thin-wall stainless steel with a blunt, low-trauma tip and micro-port geometry designed to preserve adipocyte and stromal vascular fraction viability. Most models are offered in small diameters (≈1.2–3.0 mm) and multiple lengths for face and body work, with etched depth marks and an ergonomic hub. It usually connects via Luer-lock to 10–60 mL syringes or adapts to power/vacuum systems, allowing low-pressure aspiration after tumescent infiltration. Versions exist as sterile single-use or reusable instruments; reusable types are steam-sterilizable per IFU with validated cleaning steps. Typical documentation includes CE/FDA class details, material certificates, and compatibility notes with microfat/nanofat processing kits.
