But it was the emotional effects that convinced Patty that he was doing the right thing. Exhibit A involved the first Lion's Den Room at Maria Fareri Children's Hospital in Westchester.
LaFontaine: "A patient in her pajamas dragged her IV pole to the door and asked if she could play a video game," LaFontaine revealed. "Within minutes a woman appeared at the door and she was sobbing.
"The woman said that the patient was her daughter, and she hadn't smiled in almost a week. 'Look at her laughing as if everything was normal,' the mother said. 'This is the best part of my day.'"
Then, a pause, and Pat added, "That's when we knew we had a success on our hands."
That "success" has been evident in many ways for innumerable patients. Among other benefits, Pat's foundation has designed and installed 20 Lion's Den rooms in hospitals across North America.
Meanwhile, the NHL has partnered to build legacy rooms during Winter Classics and All-Star Games.
"I also got football involved," Pat added. "CIC worked with the Heisman Trophy Trust to bring the top collegiate football players to the hospitals on our Lion's Den Network."
LaFontaine -- a permanent Long Islander who lives in Huntington -- eventually persuaded such industry giants as Microsoft and Google to get on the CIC bandwagon.
Microsoft built 400 mobile Xbox kiosks that could be wheeled to patient's besides. CIC helped distribute those units to 80 children's hospitals across North America.
And on Long Island, the Cohen Children's Medical Center teamed with the foundation to introduce 3D printers to further engage patients.
LaFontaine: "The printers had a profound effect on patients with eating disorders. By giving these patients control over something in their life, it started them on the path to healing."
As for Google, it partnered with CIC during COVID restrictions to provide Chromebooks and Pixel Slates to patients in an additional 42 hospitals so they could get homework assignments and stay connected to the outside world.
The beauty part for Patty takes place when he encounters someone who he'd once helped. One episode involved a patient who had a brain cyst removed and had a chance to thank LaFontaine for his personal involvement.
"You influenced my recovery," the former patient told the ex-hockey star. "That gesture showed me that you were more than a hockey player. You will always be part of our community."
The former Islander remains secure in the knowledge that he's made a major difference on the ice and off the rink as well.
More than 50,000 pediatric patients annually either visit a Lion's Den Room, play on a mobile Xbox unit or get their homework on a tablet that has been provided by LaFontaine's Companion In Courage Foundation.
As one of Pat's pals put it: "He's not only one of hockey's top all-time players but a top -100 human being as well!"
