ZOLL Files Suit Against Alsius Over Induced Hypothermia Patents

February 5, 2009 - Resuscitation device maker ZOLL Medical Corp. said this week it filed a lawsuit against Alsius Corp. and Alsius Medical Corp. in the Central District of California alleging infringement of its patents for catheter-based induced hypothermia devices.

Zoll does not currently have any induced hypothermia products on the market using these patents, but alleges Alsius violated two Zoll patents for such a device. Induced hypothermia is used to help stabilize patients suffering from sever trauma or cardiac arrest.

ZOLL Medical develop technologies that help advance resuscitation, with products for pacing, defibrillation, circulation, ventilation, and fluid resuscitation. ZOLL also designs and markets software that automates the documentation and management of both clinical and non-clinical information.

Alsius offers the Intravascular Temperature Management (IVTM) Thermogard XP, which uses a catheter is inserted into the central venous system of a critically ill or surgical patient (femoral, subclavian, or internal jugular insertion). Temperature is regulated with cooled or warmed saline circulating through the catheter balloons.
