E-Z-EM (Lake Success, New York) said that the Tyco Healthcare Group , part of Tyco International (Pembroke, Bermuda), had filed a lawsuit against the company in the federal district court in Texas alleging patent infringement related to E-Z-EM’s Empower CT and Empower CTA injector systems. This lawsuit alleges infringement of a single U.S. patent concerning medical fluid injectors.

Commenting on the lawsuit, Anthony Lombardo, president/CEO of E-Z-EM, said, “The company respects the intellectual property rights of others and intends to vigorously defend against this action.”

E-Z-EM makes contrast agents for gastrointestinal radiology. The company is the developer of VoLumen—a patent-pending, next generation low density barium sulfate suspension for use as an oral contrast in Multidetector CT (MDCT) and Positron Emission Tomography (PET/CT) studies.
