Abstract
Cooling systems for medical probe assemblies are provided. For example, a cooling system comprises a pump assembly including a control unit having a controller, a motor, and a pump head driven by the motor; a fluid reservoir; a lumen for delivering a cooling fluid to the medical probe assembly distal end; tubing extending through the pump head for conveying the cooling fluid from the fluid reservoir to the lumen; and a flow sensor for sensing the cooling fluid flow rate. The pump head is disposed between the fluid reservoir and the medical probe assembly to pump the cooling fluid from the fluid reservoir to the lumen. The flow sensor is disposed between the pump head and the medical probe assembly to sense the cooling fluid flow rate. Methods for controlling fluid flow rate through a cooling circuit and systems for using a plurality of medical probe assemblies also are provided.
