title: A transcervical chorionic villus sampling model for teaching.
abstract: We sought to create a transcervical chorionic villus sampling model for teaching that would mimic a lifelike model. A model was created using silicone resembling the maternal interface. A cervix with an endocervical canal able to accommodate a catheter and a vagina was also created. Tap water was used as the amniotic fluid. Chorionic villus sampling was accomplished using this model with the actual ultrasound machines and environment as in the real model. This simulator allowed placental placement in different locations to increase the difficulty level as well as angulations and catheter handling. Given the low cost (less than $200), this model could be used indefinitely in a relaxed and controlled environment.
