A Karman cannula is a soft, flexible, medical-grade plastic tube used by gynecologists with a manual vacuum aspiration (MVA) syringe for uterine evacuation early pregnancy loss, and endometrial biopsies. The smooth, rounded atraumatic tip minimizes tissue trauma during cervical passage, making the procedure comfortable for patients. The Karman cannula is available in sizes ranging from 4 mm to 12 mm with a standard length of 22.8 cm. This device can be connected to all standard MVA syringes for immediate clinical use.
