Nineteen of Medvedev's 21 victories have been achieved on hard surfaces
A resurgent the Russian player secured his first trophy for 882 days with a win over Corentin Moutet in the tournament final.
Medvedev, a ex- number one, has experienced a torrid season, winning just one win at the major tournaments and undergoing a meltdown at the US Open.
The player's unpredictability on the professional circuit - and difficulties with his service game in particular - caused him falling of the elite rankings and ultimately splitting with former coach Cervara.
Now training with Thomas Johansson and Goetzke, the tennis star has consistently improved in the past month - climaxing in a tightly fought competitive win over opponent Moutet.
This represents the player's maiden trophy since the Rome competition and first on a hardcourt since March of that year.
Victory also indicates the Russian has achieved 21 victories at 21 various tournaments.
"For the first time I have attended a event with my both daughters together, so to get a title is particularly special," commented ranked player Daniil Medvedev.
"This victory is in honour of my second daughter her name, because the first title I won when my first daughter Alisa was born was for her."
Medvedev, the past champion, had been defeated in his previous six championship matches, including in Halle earlier this year.
The player's retrieving play style and recurring reactions on the playing surface had led observers to doubt if his ability to play at the top level was over.
Yet the athlete has made changes in recent weeks, making an effort to advance forward and play positively, reinforced by an enhanced serving game.
The champion recovered from a deficit in the opening set against the difficult Frenchman, securing four of the concluding five games to go ahead.
The competitors swapped break points in the middle set before the Frenchman, attempting for his maiden professional championship, took control to create a decider.
He rescued four early-game opportunities in a competitive deciding set before the champion won the break to 15 to serve for the match.
Appropriately, he secured the win with a point at the net, with his opponent unable to control a shot after a lengthy match.
