Abstract

System for electrically ablating tissue of a patient through a plurality of electrodes includes a memory, a processor and a treatment control module stored in the memory and executable by the processor. The treatment control module generates an estimated treatment region based on the number of electrical pulses to be applied.

First claim

What is claimed is:

1. A device for delivery of electrical energy to a target tissue during a treatment procedure, the device comprising:
a generator, a processor, a memory, a display unit coupled to the processor, and a treatment control module, the processor coupled to the generator, the memory, and the treatment control module; the generator to deliver a number of electrical pulses to the target tissue during the treatment procedure, when executed by the processor, the treatment control module:
receives identification of a target region;
generates an enlarged target region comprising a margin surrounding the identified target region;
generates an estimated treatment region; and
generates a resulting estimated treatment area by adjusting an at least one treatment parameter such that the resulting estimated treatment area sufficiently covers the enlarged target region while minimizing ablation of good tissue; and

wherein the display unit to display the resulting estimated treatment area superimposed over the estimated treatment region.

2. The device of claim 1 , wherein the treatment procedure is irreversible electroporation.

3. The device of claim 1 , wherein the generator to operatively couples to at least two probes.

4. The device of claim 3 , wherein the at least one treatment parameter is a number of the at least two probes to be used during the treatment procedure.

5. The device of claim 3 , wherein the treatment control module further selects the number of the at least two probes to be used during the treatment procedure.

6. The device of claim 5 , wherein the estimated treatment region is enlarged to the enlarged target region by changing the number of the at least two probes to be used during the treatment procedure.

7. The device of claim 1 , wherein the at least one treatment parameter is the number of electrical pulses generated by the generator to be delivered during the treatment procedure.

8. The device of claim 1 , wherein the estimated treatment region is enlarged to the enlarged target region by changing the number of electrical pulses to be used during the treatment procedure.

9. The device of claim 8 , wherein the generator generates the changed number of electrical pulses to be used during the treatment procedure.

10. The device of claim 1 , wherein a user selects a treatment parameter.

11. The device of claim 1 , wherein a user adjusts the margin.

12. A device for delivery of electrical energy to a target tissue site during an ablation procedure, the device comprising:
a treatment console comprising a generator, a processor, a memory, and a treatment control module, the processor coupled to the memory, and the treatment control module;
the generator to deliver a number of electrical pulses to the target tissue site during the ablation procedure, the generator coupled to the processor; and
the treatment control module to be stored in the memory, and when executed by the processor, the treatment control module to:
receive identification of a target region;
generate an enlarged target region comprising a margin surrounding the identified target region;
generate an estimated treatment region;
generate a resulting estimated treatment area by adjusting at least one treatment parameter so that the resulting estimated treatment area sufficiently covers the enlarged target region while minimizing ablation of good tissue;
generate a plurality of resulting estimated treatment regions by adjusting an at least one treatment parameter; and
select, from the plurality of resulting estimated treatment regions, the resulting estimated treatment area with the smallest size that covers the enlarged target region.

13. The device of claim 12 , wherein the generator to operatively couple to at least two electrodes.

14. The device of claim 13 , wherein the at least one treatment parameter is the number of the at least two electrodes.

15. The device of claim 12 , wherein the treatment control module is further configured to determine if the resulting estimated treatment region does not sufficiently cover the enlarged target region.

16. The device of claim 15 , further comprising a display unit coupled to the processor, the display unit to display the at least one treatment parameter.

17. The device of claim 16 , wherein the display unit to display the target region superimposed with the estimated treatment region.

18. The device of claim 12 , wherein the at least one treatment parameter is the number of electrical pulses to be delivered to the target region.

19. A device for delivery of pulsed electrical energy to a target tissue during a treatment procedure, the device comprising:
a processor, a memory, and a treatment control module, the processor coupled to the memory and the treatment control module;
the treatment control module to be stored in the memory and when executed by the processor the treatment control module to:
receive identification of a target region; and
generate an enlarged target region comprising a margin surrounding the identified target region;
generates an estimated treatment region;
generate a resulting estimated treatment area by adjusting at least one treatment parameter so that the resulting estimated treatment area sufficiently covers the enlarged target region while minimizing ablation of good tissue;
determine if the estimated treatment region does not sufficiently cover the enlarged target region;
generate a plurality of estimated treatment regions based on a plurality of electrical energy pulse counts; and
select a minimum number of electrical energy pulses to be delivered that covers the enlarged target region.
