A spokeswoman for former U.S. President Gerald Ford says he has undergone surgery to repair a blood vessel.
The spokeswoman says doctors performed an angioplasty on Mr. Ford, 93, Thursday at the Mayo Clinic in Minnesota. He is now reported to be resting comfortably.
The former president was admitted to the clinic in mid-August. He was fitted with a pacemaker Monday to regulate his heartbeat.
Mr. Ford is the oldest living U.S. president. He was appointed vice president in 1973 after his predecessor resigned. He became president the next year after the Watergate political scandal forced Richard Nixon from office.
Mr. Ford, a Republican, lost his bid for a full term as president to Democratic challenger Jimmy Carter in 1976.
