Abstract

The present disclosure relates to devices and methods for the cooling of ablation technology used to treat tissue. The devices and methods disclosed herein utilize a multiple use generator assembly which includes an integrated cooling system, and a disposable, single-use subassembly which includes a disposable pump head and ablation device.

Claims

1. A system for ablating tissue and the cooling of ablation probes, the system comprising:

a multiple-use housing, the multiple use housing comprising;

a first electrical connection point;

a pump having a pump motor and a drive shaft;

an energy generator; and

a single-use pump head, the single-use pump head comprising;

a rotor, the rotor having a connection point that aligns with the drive shaft of the pump;

at least one roller attached to the rotor, the at least one roller comprising up to 6 rollers;

a pump tubing track, the entirety of the pump tubing track being within the single-use pump head;

a first tube connector and a second tube connector;

a second electrical connection point;

a pump tubing, the pump tubing having a first end and a second end, the first end is connected to the first tube connector and the second end is connected to the second tube connector, the pump tubing aligning with the pump tubing track, the pump tubing contained entirely within the pump head;

a fluid source line, the fluid source line having a first end and a second end, the first end is connected to an external fluid source and the second end is connected to the first tube connector;

a probe fluid line, the probe fluid line comprising a first end and a second end, the first end is connected to the second tube connector and the second end is connected to an ablation probe handle;

a return lumen, the return lumen having a first end and a second end, the first end is connected to the ablation probe handle and the second end is connected to the fluid source, the return lumen being situated within the pump head and bypassing the pump tubing track and the at least one roller attached to the rotor; and

an ablation probe.

2. The system of claim 1, wherein the multiple-use housing further comprises a faceplate having at least one additional electrical connection point on the housing.

3. The system of claim 2, wherein the faceplate has a securement keyhole.

4. The system of claim 1, wherein the multiple-use housing further comprises a pump faceplate.

5. The system of claim 1, wherein the pump head further comprises a securement latch.

6. The system of claim 1, wherein the first electrical connection point aligns with and connects to the second electrical connection point when the pump head is attached to the housing.

7. The system of claim 1, the probe fluid line further comprising 5 lumens at the second end.

8. The system of claim 1, wherein the energy generator is capable of producing microwave energy.

9. The system of claim 1, wherein the energy generator is capable of producing irreversible electroporation energy.

10. The system of claim 1, wherein the energy generator is capable of producing radiofrequency energy.
