Post-ablation verification of lesion size
First Claim
1. A method for providing feedback regarding the results of tissue ablation, the method comprising:
- deploying one or more needles from a catheter into a target tissue;
delivering energy via at least one of the one or more needles to ablate at least a portion of the target tissue to form a lesion;
stopping energy delivery via the at least one of the one or more needles; and
measuring a tissue property via at least one of the one or more needles after the energy delivery has been stopped.

Abstract
This disclosure is directed to a method of providing feedback regarding the outcome of ablation therapy. Measuring one or more tissue properties after the ablation procedure may allow the clinician to verify the size of the lesion formed or other therapy results. In one embodiment, the invention is directed toward a method for providing feedback regarding the results of tissue ablation, the method comprising deploying one or more needles from a catheter into a target tissue, delivering energy via at least one of the one or more needles to ablate at least a portion of the target tissue to form a lesion, stopping energy delivery via the at least one of the one or more needles, and measuring a tissue property via at least one of the one or more needles after the energy delivery has been stopped. The measured tissue property may be temperature or impedance. Also, the measured tissue property may be used to determine a volume of the lesion formed by ablation therapy.

17. A system comprising:
-
a generator that generates energy to ablate at least a portion of a target tissue to form a lesion; one or more needles that deliver the energy to the target tissue, wherein at least one of the needles comprises a measurement device that measures a tissue property of the target tissue after the lesion is formed; and a processor that analyzes the measured tissue property and provides an indicator of therapy outcome based on the measured tissue property. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A computer-readable medium comprising instructions for causing a programmable processor to:
-
deliver energy via one or more needles to ablate at least a portion of a target tissue to form a lesion; receive a tissue property measurement, wherein the tissue property measurement is measured via at least one of the one or more needles after the energy delivery has been stopped; and analyze the measured tissue property and provide an indicator of therapy outcome based on the measured tissue property. - View Dependent Claims (32)
