What instruments are used to perform a chorionic villi sampling?
2 doctors weighed in across 2 answers
Ultrasound: Ultrasound is used to assess the anatomy of the fetus and placenta. This allows directed placement of the biopsy needle to get a speciman. This is usually done under local anesthesia.

Chorionic sampling: A small curette is introduced under ultrasound guidance, and a very small piece of placenta is taken and a genetic analysis is performed. An amniocentesis under ultrasound has less potential for harm, so ask your OB provider his/her advice.
