Havana , Cuba ( CNN ) -- Alan Gross , a U.S. State Department contractor jailed in Cuba , received his first visit by American doctors , Gross ' attorney said Thursday . `` A U.S. medical team did visit Alan in early July , '' Gross ' attorney , Scott Gilbert , wrote CNN in an e-mail . `` The family has received the results and , at least at this time , does not have any plans to release them to the public . '' The doctors ' visit was not previously disclosed . Gross , 64 , is serving a 15-year sentence for bringing banned communications equipment to Cuba as part of a State Department program to increase access to the internet and spread democracy on the island . Gross ' family has said that his health is failing and had asked that Cuban authorities allow American doctors to examine him . Cuban authorities had said that Gross was being adequately cared for in the military hospital where he is imprisoned , but in June said they had granted permission for doctors to visit . The change in course comes as Cuba intensifies its campaign to secure the release of Cuban intelligence agents serving lengthy prison sentences in the United States . Cuban officials argue that the men infiltrated hard-line Cuban exile groups to prevent terrorist attacks on the island . But U.S. prosecutors called the men spies , and they were convicted in 2001 . Four of the agents remain in U.S. federal prison . The fifth man , Rene Gonzalez , returned to Cuba in May after serving 14 years in prison and on supervised release . Cuba 's talks of a possible prisoner trade have been dismissed by U.S. officials , who say Gross should be released immediately . In May , Gross settled with his employer for an undisclosed sum . He and his wife , Judy , had sued Development Alternatives Inc. , and the U.S. government for $ 60 million , saying that Gross had not been properly trained to carry out his work in Cuba . The settlement did not include the government . The company hired Gross to fulfill a U.S. Agency for International Development contract to connect private citizens to the Internet in Cuba , a scarce commodity on the island . He arrived in Cuba in 2009 .
