Abstract
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.
