19 of Medvedev's twenty-one titles have been earned on hard courts
A resurgent Medvedev secured his initial title for 882 days with success over Corentin Moutet in the competition championship match.
The Russian, a ex- number one, has experienced a torrid season, achieving just one match at the Grand Slams and undergoing a meltdown at the American major.
Medvedev's varied form on the tennis tour - and struggles with his serve in specific - led to him exiting of the world's top 10 and ultimately parting ways with former coach Cervara.
Now working with Johansson and his other coach, he has gradually advanced in the past month - climaxing in a closely contested 7-5 4-6 6-3 victory over Frenchman Moutet.
It is the player's maiden trophy following the 2023 Rome Masters and initial on a hardcourt from March of 2023.
The win also indicates the Russian has secured 21 titles at twenty-one distinct events.
"This marks the first occasion I have attended a competition with my children simultaneously, so to win a trophy is really nice," said tennis professional the champion.
"This title is in tribute of my younger daughter her name, because the first title I achieved when my child Alisa was born was for her."
The athlete, the former major winner, had lost his last six title deciders, featuring in Halle earlier this year.
His defensive strategy and regular outbursts on the tennis court had led observers to wonder if his skill to compete at the elite level was finished.
However the athlete has implemented adjustments in the last few weeks, striving to come to the net and play assertively, backed up by an improved serve.
Medvedev recovered from a deficit in the initial set against the challenging Frenchman, securing four of the concluding five games to go ahead.
The pair swapped service breaks in the following set before the challenger, bidding for his first ATP Tour victory, seized the initiative to force a final set.
The opponent rescued four early opportunities in a competitive third set before the Russian broke to 15 to serve for the match.
Appropriately, the winner clinched the title with a shot at the front of the court, with the Frenchman failing to control a volley after over two and a half hours.
