Device, System, and Method for Imaging and Tissue Characterization of Ablated Tissue
First Claim
1. A system for ablating and characterizing tissue, the system comprising:
- an ablation element configured to emit ablative energy toward a tissue of interest;
an imaging apparatus configured to emit energy and collect imaging data including reflected signals from the tissue of interest; and
a characterization application comprising;
a signal analyzer for analyzing the imaging data and determining one or more signal properties from the reflected signals; and
a correlation processor configured to associate the one or more signal properties to pre-determined tissue signal properties of different tissue components through a pattern recognition technique wherein the pre-determined tissue signal properties are embodied in a database, the correlation processor further configured to identify a tissue component and an ablation level of the tissue of interest based on the pattern recognition technique.

Abstract
Disclosed herein is a system for ablating and characterizing tissue. The system comprises an ablation element configured to emit ablative energy toward a tissue of interest, an imaging apparatus configured to emit energy and collect imaging data including reflected signals from the tissue of interest, and a characterization application. The characterization application comprises a signal analyzer for analyzing the imaging data and determining one or more signal properties from the reflected signals, and a correlation processor configured to associate the one or more signal properties to pre-determined tissue signal properties of different tissue components through a pattern recognition technique. The pre-determined tissue signal properties are embodied in a database, and the correlation processor is configured to identify a tissue component and an ablation level of the tissue of interest based on the pattern recognition technique.

19. A method of ablating and characterizing one or more tissue components of a scanned object in a patient, the method comprising:
-
positioning a catheter including an ablative element and an imaging apparatus adjacent a region of interest of the scanned object; directing ablative energy from an ablative element toward the region of interest; receiving reflected signals from an imaging apparatus scanning the region of interest; determining one or more signal properties of the region of interest from the reflected signals; associating the one or more signal properties to pre-determined signal properties of tissue components of an object similar to the scanned object wherein the pre-determined signal properties comprise classification conditions stored in a data structure; and identifying one or more tissue components and their corresponding levels of ablation based on the associating. - View Dependent Claims (20, 21, 22, 23, 24)
