This paper reports a new technique of chorionic villus sampling. A new probe has been developed to allow easier passage and manipulation of the catheter and improve visualization by ultrasound. Our initial experience with this new probe-guided sampling device indicates that it simplifies the operation, and this could improve the success rate.
