A Medical Device Daily
Zoll Medical (Chelmsford, Massachusetts) said that it had filed a lawsuit against Alsius and Alsius Medical (both Irvine, California) in the Central District of California alleging patent infringement.
Zoll said the patents concern a device that controls a patient's body temperature using a catheter inserted into the bloodstream. Zoll does not currently market any products using that technology, but the company said Alsius is in violation of two patents covering such a device.
Zoll Medical specializes in technologies that help advance the practice of resuscitation. Zoll also designs and markets software that automates the documentation and management of both clinical and non-clinical information. Alsius makes temperature management devices.
