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 HYD 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.
Flight diverted to ZZZZ for passenger medical. Aircraft experienced mechanical malfunction on approach to land; Slats Drive failure. During checklist execution aircraft experienced additional mechanical malfunction; Flaps Primary Fail. SATCOM with [Ops]; [Maintenance Control]; fleet pilot and Boeing representative; confirmed No Slat; No Flap landing not covered in QRH procedures or inflight performance. Coordinated with ATC to proceed to ZZZZ1 for longer runway; clear weather and burn fuel to lessen gross weight adjustment. Adjusted gross weight to below max landing weight and assist with landing distance. EICAS only status message HYD VLV ISLN Nose Gear impacted aircraft when nose gear would not extend; Alternate Gear Extension checklist resulted in gear down and lock but loss of nose wheel steering. Captain emergency authority exercised; approach to full stop executed. Aircraft towed to parking from the runway where EMT personnel tended to ill passenger.
B787 flight crew reported a hydraulic system malfunction that led to a zero flap approach and alternate gear extension landing.
