ABSTRACT:
An intra-amniotic loop catheter which allows direct access to a free floating segment of the umbilical cord for direct blood sampling. The loop catheter is formed of a flexible, resilient material with a distal, hook shaped end which may be straightened by an insertion or a removal tool but which returns to a hook shape when released. The hook is adapted to be oriented around a free floating section of the umbilical cord to allow insertion of a blood sampling needle into the umbilical cord through an opening in the proximal region of the hook.
