Nineteen of Medvedev's 21 victories have been won on hard surfaces
A comeback the Russian player won his maiden championship for over two years with success over Corentin Moutet in the tournament title decider.
The athlete, a former number one, has experienced a difficult season, achieving just one match at the Grand Slams and undergoing a setback at the US Open.
His inconsistency on the ATP Tour - and struggles with his service game in particular - resulted in him falling of the top ten and finally separating with long-term coach Cervara.
Now working with Johansson and his other coach, the tennis star has consistently improved in the recent weeks - peaking in a tightly fought competitive triumph over challenger Moutet.
This marks his maiden championship since the Rome competition and first on a hard surface from March of that year.
The win also means Medvedev has secured 21 championships at 21 distinct tournaments.
"This marks the first occasion I am participating in a tournament with my children together, so to get a trophy is particularly special," said tennis professional Medvedev.
"This title is in dedication of my child her name, because the maiden victory I achieved when my older daughter my daughter was born was for her."
The tennis star, the past champion, had failed in his past six finals, comprising in that event in the past months.
The player's defensive approach and regular reactions on court had prompted observers to doubt if his ability to play at the highest level was finished.
But the player has made changes in recent weeks, making an effort to approach the net and perform positively, backed up by an enhanced service.
Medvedev came back from a break down in the opening set against the difficult opponent, winning four of the concluding five points to gain the advantage.
Both players traded breaks in the following set before the challenger, striving for his maiden professional title, took control to force a third set.
He saved four initial chances in a tight final set before Medvedev won the break to 15 to serve for the match.
Appropriately, he clinched the win with a shot at the front of the court, with Moutet unable to handle a return after two hours and 38 minutes.
