Narrative:
Enroute we first had a medical emergency. Contacted [operations] through dispatch. I linked the [operations control] with the available doctor on board so they could discuss. It was determined to stop in ZZZZ to provide medical help to our passenger. We [notified ATC] and requested to head to ZZZZ. Upon configuring into ZZZZ; we had no flap/slats so we decided to continue on to ZZZZ1 because of a longer runway and we were still in communications with boeing. Obviously; we [notified ATC of our medical situation]. Upon determining best course of action without procedure; we dumped fuel; headed to ZZZZ1 and manually extended gear as normal extension was inoperative as well and landed uneventfully. Towed to gate. Mechanical failure; no defined procedure. Only indication was a status message which indicated hydraulic vlv isol nose gear. Maybe this valve should be rated higher than just a status message. No other indications until trying to extend slats; flaps and gear.
