Stevens Harvesting Cannula Archives

The Stevens Harvesting Cannula is a fine-gauge, blunt-tipped cannula specifically designed for the gentle aspiration of fat during autologous fat transfer, particularly for facial and delicate area grafting. Its small diameter (often 18-20 gauge) and single or multiple small side ports allow for low-pressure, low-trauma fat collection, which is believed to better preserve adipocyte integrity and viability. This design is favored for procedures requiring high-quality fat for subtle, natural-looking volume enhancement.

Key Features:

Fine gauge (e.g., 18G, 20G) with a blunt tip for gentle, low-trauma fat harvesting.
Small side port(s) designed to reduce shear stress on fat cells.
Aims to maximize the survival rate of harvested adipocytes for grafting.
Ideal for collecting fat for delicate facial, hand, or breast augmentation.
Often used with a Luer Lock syringe for manual, low-pressure aspiration.
A specialized tool focused on the quality of fat harvested, not just volume.
