The Karman Cannula is a particular disposable device that is a component of the Manual Vacuum Aspiration apparatus. The cannula connects with a matching MVA syringe to create suction manually during certain gynecologic procedures. The flexible design along with the smooth catheter surface allows controlled manipulation by professionals. The rounded tip helps in proper insertion as per the medical guidelines. Several sizes can be chosen based on the specific needs. The transparent cannula may help in visualizing the aspirated material during the procedure. It could also be useful in performing endometrial biopsies in skilled hands.
