Abstract
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.

A pump system for pumping a coolant fluid for cooled radiofrequency ablation treatment, comprising:
- a housing having a front side, a back side, a right side, a left side, a top surface, and a bottom surface;
- and
- a plurality of peristaltic pump assemblies;
- wherein 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;
- and
- wherein the top surface slopes down and away from the central channel towards the right side and the left side.
A cooled radiofrequency ablation system comprising:
- a generator, the generator comprising a housing having a front surface including a display, a back side, a right side, a left side, a top surface, and a bottom surface;
- and
- a pump system for pumping a coolant fluid for cooled radiofrequency ablation treatment, the pump system comprising a housing having a front side, a back side, a right side, a left side, a top surface, a bottom surface, and a plurality of peristaltic pump assemblies;
- wherein 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;
- wherein the top surface slopes down and away from the central channel towards the right side and the left side;
- and
- wherein the generator and the pump system have a generally matching footprint such that the pump system sits on the top surface of the generator.
