Description CryoCath Technologies has catheter-based cardiac therapies down cold. The company creates cryotherapy products that use extremely cold temperatures to treat diseased tissue while leaving surrounding tissue largely unaffected. Cryotherapy use has been limited by the difficulty of delivering it to the right place in a minimally invasive manner. However, CryoCath has developed a steerable catheter-based system to deliver cold therapy to almost any location in the body that is accessible through the blood vessel system. CryoCath concentrates its efforts on developing products that address cardiovascular disease, through cardiac ablation and other means. The company is a subsidiary of Medtronic.
