title: [Chorionic villus sampling training method].
abstract: OBJECTIVE
  Chorionic villus sampling (CVS) in the first trimester of pregnancy has become a major tool in prenatal diagnosis. To increase the safety of CVS during training period, we have built a "BT-Trainer".
  
  
  METHODS
  A medical device has been developed which simulates the in vivo procedure with the various layers to cross. The stratum of the layer and the accessibility of the placenta can modulate the level difficulty.
  
  
  CONCLUSIONS
  Traditional strategies for clinical teaching are often insufficient and trainees may fail to achieve competence in even basic procedural skills. We present herein an easy and reproducible model of "BT-Trainer" which allows a safe and repeatable training. Efficacy of this model is currently under evaluation in a teaching program. This trainer could help gynaecologists in order to learn gradually and safely the technique and to enhance their skills and coordination.
