a medical device used for the manual removal of uterine contents. It's primarily used in early pregnancy termination, miscarriage management, and retained products of conception removal. The set typically includes a syringe, cannulas, and sometimes dilators.
Key Components and Features:
Syringe:
The core of the MVA set is a syringe (usually 60 ml) that creates a vacuum for aspiration. It may have single or double valves to control suction.
Cannulas:
These are flexible, smooth tubes with rounded tips and side holes (eyes) for atraumatic insertion into the uterus. Cannulas come in various sizes (typically 4mm to 12mm) to accommodate different gestational ages.
Dilators:
In some cases, dilators are included to gently widen the cervical opening to allow for cannula insertion.
