Nineteen of Medvedev's 21 titles have been won on hard surfaces
A resurgent the Russian player claimed his initial championship for over two years with a win over Corentin Moutet in the competition title decider.
Medvedev, a ex- number one, has experienced a challenging period, managing just a single victory at the Grand Slams and undergoing a setback at the US Open.
The player's unpredictability on the professional circuit - and issues with his serving in particular - resulted in him dropping out of the world's top 10 and ultimately parting ways with former mentor Gilles Cervara.
Now collaborating with Johansson and his other coach, he has gradually progressed in the last few weeks - culminating in a closely contested three-set triumph over Frenchman Moutet.
This marks the player's first title since the 2023 Rome Masters and initial on a hard surface from that period of 2023.
Success also means the Russian has achieved 21 victories at 21 distinct competitions.
"This marks the first occasion I am participating in a competition with my both daughters together, so to secure a championship is really nice," commented world number 14 the champion.
"This victory is in dedication of my younger daughter Victoria, because the initial championship I won when my child my daughter was born was for her."
Medvedev, the former major winner, had failed in his past six title deciders, featuring in that event in the past months.
Medvedev's defensive play style and regular reactions on court had led commentators to question if his skill to compete at the elite level was concluded.
But the 29-year-old has made changes in the past month, attempting to come to the net and play positively, reinforced by an better service.
Medvedev recovered from a deficit in the initial set against the difficult opponent, winning 4 of the last five games to gain the advantage.
Both players swapped break points in the following set before the Frenchman, striving for his initial ATP Tour championship, seized the initiative to push for a third set.
The opponent saved 4 early opportunities in a competitive third set before Medvedev secured a break to that score to serve for the match.
Fittingly, he secured the win with a point at the net, with his opponent failing to handle a shot after a lengthy match.
