A slender, sharply-pointed metal tube intended for transabdominal chorionic villus sampling (CVS) to obtain intrauterine specimens of the chorionic villi for genetic testing to detect chromosomal disorders in the foetus during the first trimester of pregnancy. It is introduced transcutaneously into the uterus, possibly using a guide cannula and under ultrasonographic guidance, and may include connectors, tubing and aspiration syringe. This is a single-use device.
