19 of the Russian's 21 victories have been won on hard surfaces
A revitalized the Russian player claimed his maiden trophy for 882 days with a win over Frenchman Moutet in the tournament championship match.
The Russian, a former world number one, has had a torrid season, managing just one win at the big events and suffering a setback at the American major.
Medvedev's varied form on the professional circuit - and difficulties with his serve in particular - led to him falling of the world's top 10 and finally splitting with long-time trainer Cervara.
Currently working with Johansson and his other coach, Medvedev has gradually improved in the past month - peaking in a closely contested competitive triumph over opponent Corentin Moutet.
This represents Medvedev's initial championship after the Rome competition and initial on a hardcourt from March of the previous year.
Success also means Medvedev has won twenty-one titles at 21 distinct competitions.
"This marks the first occasion I am participating in a tournament with my children together, so to win a trophy is especially meaningful," stated ranked player the champion.
"This title is in honour of my child my daughter, because the maiden victory I got when my first daughter my daughter was born was for her."
The tennis star, the former major winner, had failed in his last six championship matches, including in the German tournament earlier this year.
His defensive approach and recurring outbursts on the playing surface had led commentators to question if his skill to play at the top level was over.
But the athlete has altered his approach in recent weeks, making an effort to advance forward and compete positively, reinforced by an improved service.
Medvedev came back from a deficit in the initial set against the tricky opponent, taking four of the concluding five points to take the lead.
The pair exchanged break points in the following set before the Frenchman, attempting for his first tour championship, took control to force a third set.
He defended 4 initial chances in a tight third set before the champion won the break to that score to serve for the match.
Appropriately, he clinched the win with a rally at the net area, with the Frenchman incapable to control a volley after two hours and 38 minutes.
