19 of the Russian's 21 titles have been won on hardcourt
A resurgent the Russian player claimed his first championship for nearly 30 months with success over Corentin Moutet in the competition final.
Medvedev, a former world number one, has had a difficult year, managing just one match at the big events and undergoing a meltdown at the US Open.
The player's varied form on the ATP Tour - and difficulties with his serving in specific - caused him exiting of the elite rankings and finally splitting with long-term coach Gilles Cervara.
Now working with Johansson and Goetzke, he has gradually improved in the recent weeks - peaking in a tightly fought competitive win over challenger Moutet.
It is his first trophy after the Rome competition and first on a hard court from March of that year.
Success also indicates the Russian has achieved 21 championships at 21 different competitions.
"For the first time I have attended a event with my children together, so to get a trophy is really nice," commented ranked player Daniil Medvedev.
"This title is in honour of my younger daughter Victoria, because the maiden victory I achieved when my child her name was born was for her."
The athlete, the former major winner, had been defeated in his last six title deciders, featuring in the German tournament in the past months.
His counter-punching strategy and frequent outbursts on court had caused commentators to question if his skill to compete at the top level was concluded.
But the athlete has altered his approach in the last few weeks, attempting to come to the net and play aggressively, supported by an better service.
Medvedev fought back from a deficit in the opening set against the challenging opponent, winning four of the last five games to gain the advantage.
Both players exchanged breaks in the middle set before Moutet, bidding for his initial ATP Tour championship, took control to create a third set.
The opponent saved four initial chances in a close final set before the champion secured a break to that score to serve for the match.
Fittingly, the winner earned the win with a rally at the net area, with his opponent failing to manage a shot after two hours and 38 minutes.
