ABSTRACT:
An embryo-transfer catheter has an extruded shaft with a gas-filled lumen that extends helically along the catheter to provide an ultrasound marker. The catheter has a side opening close to a closed rounded patient end. The catheter could be completely transparent to x-rays or the plastics from which it is formed could incorporate an x-ray opaque filler, such as barium sulphate.
