In late 2016, CEO Howard Root decided he was done running a medical products company.
He and his board sold Vascular Solutions, the public company Root had started and led for 20 years, for about $1 billion.
Root, 58, had been acquitted earlier in 2016 by a federal jury in Texas that found Root and Vascular were not guilty of federal charges of unauthorized use of a Vascular Solutions product.
"I feel vindicated, but outraged by the obscene legal process that I had to endure and the public trashing that my company had to take," Root said at the time.
Root, a lawyer by training, also wrote a book about the five-year legal fight called "Cardiac Arrest."
Root, who sold 650-employee Vascular at a premium to larger Teleflex, had assumed that he would work until 65 in the medical products business.
"I went through that trial and I didn't want to run a [publicly held medical-device company] anymore," Root recalled last week. "I was too young to stay home. I wasn't wired to play golf all day. I did charitable things and worked on criminal justice reform and educational things."
Root, a Lake Minnetonka resident, whose stake in Vascular Solutions was valued at about $40 million, also decided to pursue a recreational interest.
