Medical equipment for trophoblast biopsy

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.
