An embryo transfer catheter or the like has electrical resistance heating elements extending along its shaft and connected to a battery in the catheter hub or to a separate power source via a cable. Alternatively, the shaft may be extruded with two channels in its wall connected with inlet and outlet connectors on the hub. Pipes connected with the connectors supply warmed fluid from a heat exchanger to one channel and return fluid to the exchanger from the other channel.
