Cardium Reports on Science Channel Series Featuring InnerCool's Endovascular Cooling During Brain Surgery at Stanford University

SAN DIEGO, April 29 /PRNewswire-FirstCall/ -- Cardium Therapeutics (Amex: CXM) and its operating unit InnerCool Therapies announced today that InnerCool's endovascular Celsius Control System was featured on Science Channel's "Cool Stuff: How It Works." The segment (episode 5) aired April 25, 2008, and is scheduled to be rebroadcast at 8:30 p.m. and 11:30 p.m. (ET/PT) on May 9, 2008.

The episode featured InnerCool's Celsius Control(TM) endovascular system during a 6-hour brain surgery at Stanford University School of Medicine in Palo Alto, California, during which Dr. Gary K. Steinberg and his surgical team cooled a patient with InnerCool's endovascular temperature modulation system.

"InnerCool's endovascular systems are well designed to meet the high performance needs of the operating room. We are pleased that our Celsius Control System was profiled on Science Channel's 'Cool Stuff' series highlighting the importance of our endovascular temperature modulation system in neurologic surgeries. We believe our low-profile, high-performance endovascular cooling system has the capacity to rapidly achieve and maintain cooling of patients undergoing these critical brain surgeries, such as the one performed in the segment," stated Christopher J. Reinhard, Chairman and Chief Executive Officer of Cardium Therapeutics and InnerCool Therapies.

"Although the precise mechanism of mild cooling's protective effect on the brain is unclear, it appears to blunt the detrimental cascade of events at the cellular level that occurs during the minutes, hours, and sometimes even days after an adverse neurologic event," stated Dr. Steinberg, Lacroute-Hearst Professor and Chairman of the Department of Neurosurgery at Stanford. "Hypothermia therapy is increasingly being used for neuroprotection during neurovascular surgery to improve neurologic function and decrease disability." Dr. Steinberg has been using therapeutic hypothermia in the clinic since 1991 and since that time has used it in more than 2,500 patients with cerebrovascular problems intended to minimize the high risk of stroke and ischemic brain damage.

Patient temperature modulation is a rapidly-advancing field focused on preserving ischemic tissue and improving patient outcomes following major medical events such as stroke, cardiac arrest and heart attack, as well as in the management of patients experiencing trauma or fever. Temperature modulation is intended to cool patients in order to reduce cell death and damage caused by ischemic events in which blood flow to critical organs such as the heart or brain is restricted, and to prevent or reduce associated injuries such as adverse neurologic outcomes.

InnerCool's Patient Temperature Modulation Systems

InnerCool's endovascular approach to patient temperature modulation is based on a single-use flexible metallic catheter and a fully-integrated cooling system, which allows for rapid and controlled cooling and re-warming. InnerCool's endovascular system integrates a number of desirable features including a slim catheter profile, a highly efficient flexible metallic thermal transfer element, a built-in temperature monitoring sensor, and a programmable console capable of rapidly and controllably inducing, maintaining and reversing therapeutic cooling. The Celsius Control System powers InnerCool's Accutrol(TM) catheter, which has a flexible metallic temperature control element and a built-in temperature feedback sensor to provide fast and precise patient temperature control. The Celsius Control System has received FDA 510(k) clearance for use in inducing, maintaining and reversing mild hypothermia in neurosurgical patients, both in surgery and in recovery or intensive care. The system has also received FDA clearance for use in cardiac patients in order to achieve or maintain normal body temperatures during surgery and in recovery / intensive care, and as an adjunctive treatment for fever control in patients with cerebral infarction and intracerebral hemorrhage. Potential additional applications of the technology include endovascular cooling for cardiac arrest, acute ischemic stroke and myocardial infarction (heart attack).

InnerCool's next-generation RapidBlue(TM) system for high-performance endovascular temperature modulation is expected to receive FDA clearance in the second quarter 2008, and to initially have the same clearance as the Celsius Control System. The RapidBlue system includes a programmable console with an enhanced user interface and a catheter designed to quickly modulate patient temperature in association with surgery or other medical procedures. The RapidBlue system powers InnerCool's Accutrol(TM) catheter, which has a flexible metallic temperature control element and a built-in temperature feedback sensor to provide fast and precise patient temperature control.

InnerCool's CoolBlue surface temperature modulation system, which includes a console and a disposable CoolBlue(TM) vest with upper thigh pads, is designed to provide a complementary tool for use in less acute patients or in clinical settings best suited to prolonged temperature management. InnerCool's CoolBlue vest and thigh pads wrap the body without requiring any adhesives to stick to the skin and produce cooling rates of around 1 degree Celsius per hour, i.e. similar to those of currently-marketed surface cooling systems and endovascular systems using inflatable balloon-based catheters. InnerCool's CoolBlue external or surface-based temperature modulation system is designed to cool or warm patients from outside of their bodies and is intended for use in less acute settings such as in-hospital fever management.
