The A.F.T. Cannulas were designed with smooth edges to minimize possible cell damaging mechanical trauma. All of the A.F.T. Cannulas are provided with a robust externally threaded luer lock™ hub design to provide an air tight fit on sterile disposable syringes. All A.F.T. Cannulas are fabricated using surgical grade stainless steel to maximize corrosion resistance during multiple cleaning and autoclave sterilizations. All of the A.F.T. Cannulas are supplied with reusable stylets to unclog the instrument. Each A.F.T Cannula has the model number clearly labeled, which indicates the diameter and length for easy reference during surgery.
