Philips Healthcare has launched its InnerCool RTx endovascular system for cooling and warming, which provides whole-body temperature modulation therapy in a closed-loop system from the inside out.

The InnerCool RTx can raise and lower the body temperature of certain non-paralyzed, awake patients of all sizes in the intensive care setting, according to the Andover, Mass.-based company. The RTx cools and warms patients with a temperature sensor catheter, which is placed below the heart via the femoral vein. The catheter design supports precise temperature control during the induction, maintenance, and reversal phases of therapeutic hypothermia and helps to avoid the lag in core temperature measurement inherent in rectal and bladder sensors.

Once in place, the closed-loop system modulates whole-body temperature without fluid introduction or exchange by circulating cool or warm saline.

The InnerCool RTx includes a programmable console with a touch screen interface, said Philips, which can be used with both a standard catheter and the Accutrol catheter. The average cooling rates for the RTx are 4-5 degrees C/hour and the average warming rates are 2-3 degrees C/hour.

Published studies are providing insights into an expanding range of potential therapeutic modulation therapy applications, including stroke, acute MI and sudden cardiac arrest, according to Philips. These studies demonstrate the clinical impact of temperature modulation therapy for protecting critical organs following cardiac arrest, MI (prior to revascularization) and other traumatic injury.
