Nineteen of Medvedev's 21 victories have been won on hard courts
A resurgent the Russian player secured his maiden title for 882 days with victory over Corentin Moutet in the tournament title decider.
Medvedev, a ex- world number one, has experienced a torrid season, winning just one match at the big events and undergoing a meltdown at the US Open.
Medvedev's unpredictability on the tennis tour - and difficulties with his serve in especial - caused him dropping out of the top ten and ultimately separating with long-term coach Gilles Cervara.
Presently training with his coach and Rohan Goetzke, he has consistently progressed in the last few weeks - peaking in a closely contested three-set victory over opponent Moutet.
This marks his first championship since the 2023 Rome Masters and initial on a hard surface since that period of that year.
Victory also indicates he has achieved 21 championships at 21 various tournaments.
"For the first time I'm at a event with my children at once, so to win a title is particularly special," said ranked player the champion.
"This title is in dedication of my second daughter her name, because the maiden victory I won when my child my daughter was born was for her."
The tennis star, the 2021 US Open champion, had failed in his past six finals, featuring in Halle in the past months.
Medvedev's retrieving play style and recurring reactions on the tennis court had caused commentators to question if his skill to compete at the top level was concluded.
But the athlete has implemented adjustments in recent weeks, striving to advance forward and compete assertively, supported by an enhanced service.
The champion fought back from a deficit in the opening set against the challenging opponent, taking 4 of the last five exchanges to gain the advantage.
The pair traded breaks in the second set before the Frenchman, attempting for his maiden tour victory, took control to push for a decider.
He rescued four early-game chances in a competitive third set before the Russian secured a break to fifteen to close out the victory.
Appropriately, he secured victory with a point at the net area, with his opponent failing to control a return after a lengthy match.
