The CryoConsole

The CryoTherapy Console: Safety, Ease of Use, and Convenience

Our CryoTherapy system uses catheters that are controlled by an advanced microprocessor-based electromechanical refrigeration console. The console processes the refrigerant, which when vaporized within the distal tip of the catheter, creates cryogenic temperatures.

The refrigerant is delivered as a liquid via a small hair-like injection tube to the catheter tip. The resultant vapor is returned to the console through an outer lumen maintained under vacuum.

Thermocouples, placed in the catheter tip, feed temperature information back to the microprocessor, which modulates the flow under which the refrigerant is delivered to affect temperatures.

Other design features provide the electrophysiologist signals to help map electrically the area of the heart to be treated with CryoTherapy. The console incorporates several features unique to CryoCath. The microprocessor-based system controls refrigerant pressure and flow, allowing for precise energy delivery and temperature control. The user interface also allows all patient and procedure information to be stored within the console for later retrieval and use.

Intuitive touch-screen operation

The cryoconsole is controlled through an easy-to-use touch-screen interface. From this interface, the user can choose CryoMapping or CryoAblation mode and set the time and temperature for the procedure.

The system automatically recognizes the connected catheter and loads the appropriate interface software and pre-set configurations for that catheter, but these pre-sets are also adjustable by the operator.

Once an ablation site is confirmed, the operator can easily proceed from CryoMapping to CryoAblation by pressing the "Go to Ablation" button. The cryoconsole can also be connected to any commercial EP signal-recording system to provide electrogram signals.

A robust safety system

Multiple features are built into our catheter-console system to ensure safety. First, the system is always under vacuum. This is a safety feature that enables the system to detect fluid ingress and stop the procedure.

Multiple connector checks confirm that everything is properly connected prior to an injection being enabled. And a sophisticated flow-monitoring algorithm monitors the flow of the refrigerant and return vapor and halts the injection if the flow is outside normal parameters.

A vent system in the console draws back the liquid refrigerant after each injection.
