Pump assemblies and systems are provided. For example, a pump assembly comprises a pump head, a bezel surrounding an outer perimeter of the pump head, a motor, and tubing. The bezel comprises a bezel upper side, a bezel lower side opposite the bezel upper side, a bezel inlet side extending from the bezel upper side to the bezel lower side, and a bezel outlet side opposite the bezel inlet side and extending from the bezel upper side to the bezel lower side. The bezel defines an inlet channel on the bezel inlet side and an outlet channel on the bezel outlet side, each of the inlet channel and the outlet channel guiding the tubing into the pump head. An exemplary pump system comprises a plurality of pump assemblies that each supply a fluid to a cooling circuit and a base for supporting the plurality of pump assemblies.

Peristaltic pump assembly and system

Pump heads for peristaltic pump assemblies are provided. For example, a pump head for a peristaltic pump comprises an occlusion bed, a rotor guide, a rotor assembly positioned between the occlusion bed and the rotor guide, and a pathway for tubing. The pathway comprises an inlet portion, an outlet portion, and a connecting portion that connects the inlet and outlet portions. The inlet portion is defined between the occlusion bed and the rotor guide, the outlet portion is defined between the occlusion bed and the rotor guide, and the connecting portion is defined between the occlusion bed and the rotor assembly. Further, the occlusion bed is movable with respect to the rotor guide and the rotor assembly. In exemplary embodiments, the pump head urges fluid flow through the tubing to supply a cooling fluid to a medical probe assembly for delivering energy to a patient's body.

Pump head for a peristaltic pump

A pump system for pumping a coolant fluid for cooled radiofrequency ablation treatment includes a housing having a front, a back, a right side, a left side, a top surface, and a bottom surface, and a plurality of peristaltic pump assemblies. The top surface of the housing includes a central channel between at least two of the peristaltic pump assemblies configured to drain fluid away from the front of the housing. A cooled radiofrequency ablation system additionally includes a pump system and a generator having mating surfaces such that the pump system can sit stably on top of the generator.
