Safe sampling and procedure for chorionic villus sampling.
Two echogenic coaxial needles to ensure optimal transabdominal chorionic villus sampling under ultrasound monitoring.
Guide needle equipped with a removable stylet to penetrate the abdomen without risk of coring tissue.
Thin sampling needle inserting in the guide needle in the place of the stylet to perform the biopsy.
The guide needle and sampling needle have echogenic marking by sandblasting at 5 mm from the tip to ensure optimal visibility of needles during ultrasound monitoring.
The guide needle allows for resampling in situ without having to insert another needle into the patient.
