Abstract

An improved user interface system for an irreversible electroporation (IRE) system is provided. User interfaces are provided that dynamically display information provided by an operator or provided by the IRE system during setup, planning, and implementation stages of an IRE procedure in a more intuitive and efficient manner. As a result of being provided the user interfaces described herein, operators can plan and implement more effective IRE procedures to the benefit of a patient.

First claim

What is claimed is:

1 . A system comprising:
a generator coupled to a processor, the generator configured to deliver at least one electrical pulse to a target tissue to electroporate the target tissue; a display device in communication with the processor; and a memory in communication with the processor, the memory storing instructions that, when executed, cause the processor to perform operations including:
monitor, in real-time, a current and a voltage of the at least one electrical pulse delivered to the target tissue by the generator;
provide a user interface on the display device for displaying, in real-time, one or more graphs of the current and voltage of the at least one electrical pulse.

2 . The system of claim 1 , wherein the one or more graphs include a vertical line grid or bar graph of each of the current and voltage of the at least one electrical pulse.

3 . The system of claim 2 , wherein each individual bar of the one or more graphs represents a delivered pulse of the at least one electrical pulse.

4 . The system of claim 3 , wherein a height of each bar of the one or more graphs represents a corresponding current or voltage value of the delivered pulse.

5 . The system of claim 3 , wherein the operations further include a zoom in on the delivered pulse on the one or more graphs upon a user input.

6 . The system of claim 2 , wherein delivered pulses of the at least one electrical pulse are shown in sequence from left to right relative to an orientation of the one or more graphs.

7 . The system of claim 1 , wherein the operations further include a display, in real-time, of how much treatment time remains.

8 . The system of claim 1 , wherein the operations further include a display, in real-time, of whether a pulse of the at least one electrical pulse has been successfully delivered.

9 . The system of claim 1 , wherein the operations further include a display of an icon indicating which probe pair is currently delivering the at least one electrical pulse.

10 . The system of claim 1 , wherein the operations further include a display of a charging voltage.

11 . The system of claim 1 , wherein the operations further include a display of an indication of electrocardiogram (ECG) synchronization.

12 . The system of claim 1 , wherein the operations further include a display of a rate of treatment progress.

13 . A system comprising:
a generator coupled to a processor, the generator configured to deliver at least one electrical pulse to a target tissue to electroporate the target tissue; a display device in communication with the processor; and a memory in communication with the processor, the memory storing instructions that, when executed, cause the processor to perform operations including:
monitor, in real-time, a current and a voltage of the at least one electrical pulse delivered to the target tissue by the generator; and
display, in real-time, the current and the voltage of the at least one electrical pulse, wherein the display includes one or more graphs showing the current and voltage of each pulse of the at least one electrical pulse after each electrical pulse is delivered before a subsequent electrical pulse is delivered.

14 . The system of claim 13 , wherein the one or more graphs include a vertical line grid or bar graph.

15 . The system of claim 14 , wherein each individual bar on the one or more graphs represent a delivered pulse.

16 . The system of claim 14 , wherein the operations further include a zoom in on a delivered electrical pulse on the one or more graphs upon a user input.

17 . The system of claim 13 , wherein the operations further include a display, in real-time, of whether a pulse of the at least one pulse has been successfully delivered.

18 . The system of claim 13 , wherein the operations further include a display of a charging voltage.

19 . The system of claim 13 , wherein the operations further include a display of an indication of electrocardiogram (ECG) synchronization.

20 . The system of claim 13 , wherein the operations further include a display of a rate of treatment progress.
