Product Information
The PolarCath Peripheral Dilatation System delivers cryo therapy and is designed to initiate both mechanical and biological responses in order to produce beneficial vascular effects. CryoPlasty Therapy, through the use of the PolarCath Peripheral Dilatation System, combines a unique application of cold therapy with angioplasty for the results you want now and the benefits you may need later.
