The Philips InnerCool RTx Endovascular System for cooling and warming provides advanced whole body temperature modulation therapy in a closed-loop system from the inside out.

The Philips InnerCool RTx Endovascular System for cooling and warming provides advanced whole body temperature modulation therapy in a closed-loop system from the inside out.

Dynamically modulates temperature (defined as a change in temperature of >4.0°C/hour) for rapid cooling, with the option of gradual warming.

Fastest cooling and warming rates in the industry

  • Average cooling rates of 4.0-5.0°C/hr¹
  • Average warming rates of 2.0-3.0°C /hr¹
  • Gradual warming of 0.1-1.2°C/hr

Cools non-paralyzed patients
As a matter of survival, our physiology resists being cooled. Shivering, the body’s natural defense to cooling, produces more body heat. Shivering also increases overall metabolic activity, dramatically increasing oxygen demand and consumption. This can have deleterious effects for patients who have suffered a global ischemic event. Overcoming this increase in metabolic heat is a daunting task which, for most cooling systems, requires that the physician paralyze the patient to eliminate shivering. Even then, time to target temperature is, at best, a few hours.
 
The challenge is to quickly get below the shivering threshold, where diminished shivering results in less resistance to cooling therapy and fewer complications. This unique approach to therapeutic hypothermia rapidly achieves maximum cooling for neuroprotection and is comfortable for the patient, while avoiding risks inherent with paralytic agents such as masking seizures or masking inadequate levels of sedation. The rapid cooling power of the InnerCool RTx enables clinicians to cool awake, non-paralyzed patients.²

Provides precise temperature control with the Accutrol™ Catheter, which is the only temperature modulation catheter with an integrated temperature sensor.  This innovative catheter design supports precise temperature control during the induction, maintenance, and reversal phases of therapeutic hypothermia.¹

Effectively cools across the full spectrum of patients, including those with high body mass index (BMI) (>30kg/m²), who often are considered difficult to cool.¹

Easy insertion and removal of the proprietary cassette enables effective heat exchange via a closed-loop system. The console has an intuitive user interface, and is compact and easy to move as needed.
