The federal government can depose employees of Boston Scientific's star-crossed Guidant subsidiary for a whistleblower lawsuit alleging violations of the False Claims Act.

Boston Scientific's Guidant subsidiary

For Boston Scientific (NYSE:BSX) and its ongoing legal woes over the blockbuster acquisition of Guidant Corp. , you win some and you lose some.

The Natick, Mass.-based medical device company won a bid in December to compel the release of Medicare documents in a whistleblower lawsuit accusing Guidant and its corporate parent of concealing problems with Guidant's implantable cardiac defibrillators.

But last week a judge in Minnesota ruled that Boston Scientific must allow its employees to be deposed for the lawsuit, for testimony on the design and testing of the allegedly faulty implants, according to court documents.
