The PassPort Button™ Cannula is manufactured from soft and flexible silicone material that will conform to smaller portal incisions and protect soft tissue and cartilage while maximizing visibility and maneuverability inside and outside of the arthroscopic work space. The double-dam one-piece molded design has low profile flanges that seat flush to the skin and soft tissue. These flanges create a stable portal that allows instruments to be inserted and removed, without the concern of cannula loss. They are easily introduced by grasping the inside flange with a curved hemostat and inserting into the incision.
