SAN DIEGO, Feb. 12 Cardium Therapeutics (NYSE Alternext US: CXM) and its operating unit InnerCool Therapies today reported that InnerCool's CoolBlue surface temperature modulation system was highlighted in a television segment that aired on Chicago's NBC 5 News. The story can be viewed at nbcchicago.com/health/tips_info/This_is_Your_Brain_on_Ice_Chicago.html. The segment features a maternity patient who suffered cardiac shock while delivering her baby at Rush University Medical Center in Chicago. The baby was saved as a result of physicians performing an emergency Caesarean section surgery - however the mother was clinging to life in a coma and was considered likely to be "brain dead." Over 40 minutes and a series of electric shocks the mother was resuscitated while she was simultaneously cooled with InnerCool's CoolBlue surface cooling system. Months later, she appears fully recovered and with normal neurological function. The attending physicians, Drs. Richard E. Temes and Omar Lateef, expressed their belief that hypothermia can improve brain recovery in post-cardiac patients and should be widely used. Dr. Temes noted that "hypothermia is perhaps the most powerful neuroprotecting agent out there." Dr. Richard Bernstein who heads Northwestern's Therapeutic Cooling Program stated, "80 percent of hospitals that should be doing this are not. It takes a champion and some pressure from patient advocacy groups to make it happen."
"There has been increasing interest in patient temperature modulation therapy as a result of the growing number of hospitals and EMS providers adopting cooling protocols for out-of-hospital and in-hospital cardiac arrest patients. This recent news story is yet another example of how a patient recovered neurological function following an in-hospital cardiac arrest who was provided an opportunity to potentially benefit from our cooling technology," stated Christopher J. Reinhard, Chairman and Chief Executive Officer of Cardium Therapeutics and InnerCool Therapies. "We believe InnerCool is the only company positioned to offer a comprehensive portfolio of best-in-class endovascular and surface cooling solutions to the growing number of hospitals and healthcare providers in this rapidly expanding therapeutic area."
CoolBlue(TM) Surface Temperature Modulation System
InnerCool's CoolBlue surface temperature modulation system, which includes a console and a disposable CoolBlue 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 1C 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. InnerCool's CoolBlue nurse-friendly and cost-effective surface temperature modulation system is also now available for sale in Europe and Australia through recently-completed distributorship agreements.
RapidBlue(TM) Endovascular Temperature Modulation System
InnerCool's RapidBlue system for high-performance endovascular temperature modulation includes a programmable console with an enhanced user-friendly interface and touch panel screen and powers the low profile flexible Accutrol(R) catheter to quickly modulate patient temperature at cooling rates of 4-5 degrees Celsius per hour or warming rates of 2-3 degrees Celsius per hour. The Accutrol catheter, which has a flexible metallic temperature control element (TCE(R)) and a built-in temperature feedback sensor to provide fast and precise patient temperature control, can accurately measure core body temperature within 0.1 degree Celsius. Its novel software control algorithm provides automated and precise body temperature control, eliminating the use of peripheral temperature probes which are generally slow in responding to core temperature changes.
The RapidBlue console and Accutrol catheter can quickly and accurately modulate whole body temperature without introducing or exchanging any fluid within the body. The system functions by programmably circulating cold or warm saline in a closed circuit within the catheter to either cool or warm its outer metallic surface, which effectively conducts heat out of or into the surrounding bloodstream. The unique design of InnerCool's TCE(R), which is both thermally conductive and includes alternating surface helices to promote mixing around the TCE, further enhances heat transfer and enables rapid patient temperature modulation, even in obese patients. The catheter and TCE have a covalently-bonded heparin coating for hemo-compatibility and the catheter can be readily inserted intravenously while the patient is in an operating room or intensive care setting without the need for continuous fluoroscopy. The integrated temperature sensor allows for automated temperature management, and also eliminates the need to place bladder or other patient temperature probes which can be slow to react to changes in core body temperature, and may be uncomfortable to the patient and time-consuming to place.
Other currently-marketed endovascular systems rely on plastic-based balloon catheters that are inflated after placement in the bloodstream. Although expansion of the balloons increases their overall surface area for heat transfer, it also tends to make the catheters fairly large and rigid. In addition, they do not contain integrated temperature feedback sensors and heat transfer is limited by the very poor conductive nature of plastic. In terms of performance, a medium-sized balloon-based catheter which inflates to about 8 mm (24 French) has been reported to cool anesthetized intubated (i.e. surgical) patients at a rate of around 1 degree Celsius per hour. In comparison, InnerCool's RapidBlue System combines an ultra-thin flexible metallic catheter of only 3.5 mm (10.7 French) or 4.6 mm (14 French) with the potential to achieve cooling rates that are approximately 4-fold faster, i.e. about 1 degree Celsius per 15 minutes. Rapid cooling is considered to be particularly important for preserving tissue and organ function under conditions of acute ischemia, which result from reduced blood flow to critical tissues and organs.
The RapidBlue System can be used in inducing, maintaining and reversing mild hypothermia in neurosurgical patients, both in surgery and in recovery or intensive care. The system can also be used for 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 may include endovascular cooling for cardiac arrest (resuscitation), acute ischemic stroke, myocardial infarction (heart attack) and trauma.
Cardium Therapeutics, Inc. and its subsidiaries, InnerCool Therapies, Inc. and the Tissue Repair Company, are medical technology companies primarily focused on the development, manufacture and sale of innovative therapeutic products and devices for cardiovascular, ischemic and related indications.
Cardium's InnerCool Therapies subsidiary is a San Diego-based medical technology company in the emerging field of temperature modulation therapy to rapidly and controllably cool the body in order to reduce cell death and damage following acute ischemic events such as cardiac arrest or stroke, and to potentially lessen or prevent associated injuries such as adverse neurological outcomes.
