CHOKE ARTIST.(The Talk of the Town)(Heimlich maneuver)

Dr. Henry J. Heimlich, the recently embattled octogenarian inventor (his younger son is campaigning to discredit many of his contributions to medicine), has at least one thing to feel good about this year: his most abiding innovation, the Heimlich maneuver, just saved the life of the actor Mandy Patinkin, who lately found himself in the dire position of having an insufficiently masticated bit of Caesar salad lodged in his windpipe.

It was a sunny afternoon at Louie's, a cafe on the Upper West Side. Patinkin, his wife, Kathryn Grody, their teen-age son, Gideon Grody-Patinkin, and a friend were having a convivial lunch. "I was laughing, and all of a sudden something went down the wrong way and got stuck," Patinkin said. "First, I'm in complete shock--'I'm choking!' "

The movie, which is showing at the Tribeca Film Festival this week, is called "Choking Man."

Patinkin had spent weeks researching asphyxiation scenarios, and they were now turning into real life, like some kind of reverse-Method nightmare. The others at the table had no idea about the nature of Patinkin's latest role or the correct first-aid procedure. "We've been in therapy," Grody explained, "and we don't talk about work at home."
