A former fen-phen client of Fleming & Associates has sued the Houston-based firm and partner George Fleming, alleging they took too much expense money out of her fen-phen settlement, including a share of $29 million for echocardiograms performed on prospective clients.

Plaintiff Sandra Karnes, who hired Fleming & Associates to seek damages from pharmaceutical company Wyeth for heart-valve injury she allegedly sustained after taking the diet-drug combination known as fen-phen, seeks class certification in the suit filed in the U.S. District Court for the Southern District of Texas.
