A device or collection of devices that includes a flexible polymer tube intended to be used primarily to transfer gametes (eggs or sperm) and/or embryos into the female reproductive tract for the purpose of assisted reproduction [e.g., intrauterine insemination (IUI) or gamete intrafallopian transfer (GIFT)]. In addition to the ‘live transfer’ catheter it may also include a trial transfer catheter intended to assess/ensure that embryo placement will be successful; it typically also includes devices intended to assist catheter introduction (e.g., outer guide sheath, stylet). This is a single-use device.
