Henze was involved in crash near the Olympic park in the Brazilian city last Friday. He was taken to hospital with head injuries and underwent emergency brain surgery but died on Monday as a result of the injuries.
Henze, who was in Rio as part of the German canoe slalom coaching team, was also a former Olympian himself having won a silver medal at the 2004 Athens Olympics in the canoe slalom doubles.
According to German media, Henze’s organs have subsequently been donated to four people.
“Heart, liver and both kidneys have been successfully transplanted. Thus he has saved four lives,” a spokesperson from the Brazilian health ministry told the German newspaper Die Welt. Henze's family, who travelled to Rio after the accident, reportedly gave their consent to the transplants.
Following news of the 35-year-old’s death, the German Olympic committee DOSB said : “Words cannot describe what we feel in the team after this terrible loss.”
