Abstract
A catheter based medical device including controlled refrigerant dispersion is disclosed. The device includes a fluid injection tube that carries refrigerant from a coolant supply to the distal portion of the device. An open distal end or one or more orifices may be provided on the injection tube for the refrigerant to be expelled into an expandable chamber such as a balloon disposed on the distal portion of the catheter. The dispersion of the refrigerant from the injection tube may be controlled or manipulable to direct the refrigerant to one or more target locations.
