Peristaltic pump assembly and system

A pump system comprising:

• a plurality of pump assemblies, each pump assembly of the plurality of pump assemblies supplying a fluid to a cooling circuit;
• and
• a base for supporting the plurality of pump assemblies, wherein each pump assembly of the plurality of pump assemblies comprises:
• a motor;
• tubing;
• and
• a pump head comprising:
• an occlusion bed;
• and
• a rotor guide having a rotor guide inlet side defining a rotor guide inlet groove and a rotor guide outlet side defining a rotor guide outlet groove, where the occlusion bed and the rotor guide together define at least a portion of a pathway for the tubing through the pump head;
• and
• a fixed bezel surrounding an outer perimeter of the pump head,
• wherein the bezel defines a fixed opening that is shaped to accept a pump head cover through the fixed opening of the bezel, the bezel defining an inlet channel and an outlet channel,
• wherein the inlet channel has a first inlet width adjacent an inner surface of a bezel inlet side and a second inlet width adjacent to an outer surface of the bezel inlet side, the second inlet width being wider than the first inlet width such that the inlet channel flares away from the pump head,
• wherein the outlet channel has a first outlet width adjacent to an inner surface of a bezel outlet side and a second outlet width adjacent an outer surface of the bezel outlet side, the second outlet width being wider than the first outlet width such that the outlet channel flares away from the pump head,
• wherein an inlet bracket is attached to the inner surface of the bezel inlet side and an outlet bracket is attached to the inner surface of the bezel outlet side, and
• wherein the inlet bracket defines an inlet bracket groove that aligns with the rotor guide inlet groove and receives the tubing on the bezel inlet side, and the outlet bracket defines an outlet bracket groove that aligns with the rotor guide outlet groove and receives the tubing on the bezel outlet side.

A peristaltic pump assembly comprising:

• a motor:
• tubing;
• and
• a pump head comprising:
• an occlusion bed;
• and
• a rotor guide having a rotor guide inlet side defining a rotor guide inlet groove and a rotor guide outlet side defining a rotor guide outlet groove, where the occlusion bed and the rotor guide together define at least a portion of a pathway for the tubing through the pump head;
• a bezel surrounding an outer perimeter of the pump head;
• wherein 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, the medical probe assembly comprising:
• at least one probe comprising an electrically non-conductive outer circumferential portion, and
• an electrically and thermally-conductive energy delivery device extending distally from the electrically non-conductive outer circumferential portion for delivering one of electrical and radiofrequency energy to the patient's body, the energy delivery device comprising a conductive outer circumferential surface and one or more internal lumens for circulating the cooling fluid to a distal end of the energy delivery device,
• wherein the bezel defines a fixed opening that is shaped to accept a pump head cover through the fixed opening of the bezel and the tubing is guided between the pump head and the medical probe assembly by at least a portion of the bezel, the bezel defining an inlet channel and an outlet channel,
• wherein the inlet channel has a first inlet width adjacent an inner surface of a bezel inlet side and a second inlet width adjacent to an outer surface of the bezel inlet side, the second inlet width being wider than the first inlet width such that the inlet channel flares away from the pump head,
• wherein the outlet channel has a first outlet width adjacent to an inner surface of a bezel outlet side and a second outlet width adjacent an outer surface of the bezel outlet side, the second outlet width being wider than the first outlet width such that the outlet channel flares away from the pump head,
• wherein an inlet bracket is attached to the inner surface of the bezel inlet side and an outlet bracket is attached to the inner surface of the bezel outlet side, and
• wherein the inlet bracket defines an inlet bracket groove that aligns with the rotor guide inlet groove and receives the tubing on the bezel inlet side and the outlet bracket defines an outlet bracket groove that aligns with the rotor guide outlet groove and receives the tubing on the bezel outlet side.
