The news, which broke shortly before a trading halt could be imposed, sent the company's shares reeling. Among the counts are nine for shipping misbranded products. The other count centers on a former employee who made false statements to the government. The felony counts were connected with a device Guidant's EndoVascular Technologies unit makes for aortic aneurysms called the Ancure. Under the terms of the agreement, EndoVascular agreed to pay $43.4 million and an additional $49 million civil settlement to the government. The expenses associated with the settlement were recorded in prior periods, Guidant said.
