Abstract

The present invention relates to comprehensive systems and methods for delivering energy to tissue for a wide variety of applications, including medical procedures (e.g., tissue ablation, resection, cautery, vascular thrombosis, treatment of cardiac arrhythmias and dysrhythmias, electrosurgery, tissue harvest, etc.). In certain embodiments, systems and methods are provided for identifying and treating a target tissue region adjusting for ablation-related anatomical changes (e.g., tissue contraction).

Claims

1. A system comprising an energy delivery device and a processor, wherein the processor is configured to identify a target tissue region adjusted for ablation-related anatomical changes,

wherein identifying the target tissue region adjusted for expected ablation-related anatomical changes comprises:

a) receiving information regarding the tissue region and the energy delivery device,

b) computing a contraction region within the tissue region,

c) determining contraction points within the tissue region,

d) computing contraction deformations within the tissue region,

e) applying the computed contraction deformations, and

f) identifying the target tissue region adjusted for ablation-related anatomical changes.

2. The system of claim 1, wherein the processor is in communication with the energy delivery device.

3. The system of claim 2, wherein the processor is configured to guide positioning of the energy delivery device to a desired tissue region.

4. The system of claim 3, wherein the desired tissue region is the identified target tissue region.

5. The system of claim 1, further comprising a power supply electrically connected to the energy delivery device.

6. The system of claim 2, wherein the contraction deformations comprise contraction point distances and contraction point directions for each contraction point.

7. The system of claim 6, wherein the contraction point directions for each contraction point comprises one or more direction changes.

8. A method of ablating a tissue region comprising providing a system as described in claim 1, identifying a target tissue region adjusted for ablation-related anatomical changes, positioning the energy delivery device at the identified target tissue region, and ablating the tissue region.

9. The method of claim 8, wherein the tissue region is within a subject.

10. The method of claim 9, wherein the subject is a human subject.

11. The method of claim 8, wherein the ablated tissue region does not include tissue not included in the identified target tissue region.
