Jan 18 (Reuters) - Stryker Corp said on Wednesday that federal prosecutors have agreed to dismiss thirteen felony charges against the medical device maker, but the company will plead guilty to one misdemeanor charge and pay a $15 million fine under a settlement with the Department of Justice.

A federal grand jury in 2009 indicted the company's Stryker Biotech unit and several of its top executives, alleging they participated in an illegal marketing scheme to promote medical devices during invasive surgeries.

The company and executives were accused of promoting devices known as OP-1 Implant and OP-1 Putty in unapproved and untested ways to stimulate bone growth in long bones and in the spine, thereby causing serious harm to a number of patients.

Stryker said it would take a fourth-quarter charge of three cents per share for its settlement with the U.S. Attorney's Office for the District of Massachusetts.
