Abstract

A computing system is provided. The computing system includes a memory storing processor executable code. The computing system includes processors executing the code. The code causes the computing system to generate a graphical user interface that includes topological maps constructed from a three-dimensional anatomical model of a portion of an anatomical feature. The topological maps include an interior map view of the portion of the anatomical feature from a perspective of a device inserted into a patient. The code causes the computing system to generate a device icon on each of the topological maps. The device icon presents a real time position of an ablating surface of the device in relation to each map view of the topological maps.

First claim

What is claimed is:

1 . A computing system for visualizing a treatment device during a cardiac procedure, the system, comprising:
a communication interface that is communicatively coupled to a sensor configured to collect positional data and electrophysiological data within a cardiac anatomical structure; a display; a memory; and one or more processors that are communicatively coupled to the communication interface and the memory, wherein the one or more processors are collectively configured to:
generate a graphical user interface comprising one or more topological maps constructed from a three-dimensional anatomical model of a portion of an anatomical feature, the three-dimensional anatomical model being constructed based on sensor data obtained from an intrabody device positioned within the anatomical feature, the sensor data comprising anatomical data and electrophysiological data collected during a medical procedure, wherein the one or more topological maps comprise at least one interior map view of the portion of the anatomical feature from a simulated viewpoint located within a lumen of the anatomical feature and corresponding to a position of the intrabody device; and
generate a device icon on each of the one or more topological maps, the device icon representing a real-time location and orientation of an ablating surface of the intrabody device within the anatomical feature, the device icon being rendered based on positional tracking data obtained from one or more sensors of the intrabody device.

2 . The computing system of claim 1 , wherein the one or more topological maps comprising at least one external map view.

3 . The computing system of claim 1 , wherein the one or more processors are further collectively configured to:
generate a cloud on each of the one or more topological maps indicating, in real time, at least one ablation area based on the real-time position of the ablating surface.

4 . The computing system of claim 3 , wherein the one or more processors are further collectively configured to:
generate a tint inside the cloud indicating one or more parameters.

5 . The computing system of claim 4 , wherein the one or more parameters comprises an intensity of an ablation.

6 . The computing system of claim 4 , wherein the tint is updated in real time during ablation.

7 . The computing system of claim 1 , wherein the intrabody device comprises a catheter comprising a plurality of electrodes, and
wherein the one or more processors are further collectively configured to: generate, in real time, an identifier for each electrode of the plurality of electrodes in contact with tissue of the portion of the anatomical feature.

8 . The computing system of claim 1 , wherein the one or more processors are further collectively configured to:
monitor the real-time position of the ablating surface of the intrabody device and update, in real time, the one or more topological maps based on the real-time position.

9 . The computing system of claim 1 , wherein the graphical user interface is rendered from a perspective of the intrabody device and comprises a view from a proximate end to a distal end or a view from the distal end to the proximate end.

10 . The computing system of claim 1 , wherein the at least one interior map view comprises shading, lines, or demarcations showing texture and depth.

11 . A non-transitory computer readable storage medium storing instructions for visualizing a treatment device during a cardiac procedure performed on a heart of a patient, the instructions when collectively executed by one or more processors of a console, cause the console to perform operations including:
generating a graphical user interface comprising one or more topological maps constructed from a three-dimensional anatomical model of a portion of an anatomical feature, the three-dimensional anatomical model being constructed based on sensor data obtained from an intrabody device positioned within the anatomical feature, the sensor data comprising anatomical data and electrophysiological data collected during a medical procedure, wherein the one or more topological maps comprise at least one interior map view of the portion of the anatomical feature from a simulated viewpoint located within a lumen of the anatomical feature and corresponding to a position of the intrabody device; and generating a device icon on each of the one or more topological maps, the device icon representing a real-time location and orientation of an ablating surface of the intrabody device within the anatomical feature, the device icon being rendered based on positional tracking data obtained from one or more sensors of the intrabody device.

12 . The non-transitory computer readable storage medium of claim 11 , wherein the graphical user interface comprises one or more topological maps each presenting an external map view of the heart.

13 . The non-transitory computer readable storage medium of claim 11 , wherein the interior map view provides a perspective from the treatment device inserted into the heart.

14 . The non-transitory computer readable storage medium of claim 11 , wherein the graphical user interface comprises a cloud the interior map view indicating, in real time, at least one ablation area based on the real-time position of the treatment device.

15 . The non-transitory computer readable storage medium of claim 11 , wherein the graphical user interface comprises a tint inside a cloud indicating one or more parameters corresponding to an intensity of an ablation.

16 . The non-transitory computer readable storage medium of claim 11 , wherein the graphical user interface comprises a tint inside a cloud is updated in real time during ablation.

17 . The non-transitory computer readable storage medium of claim 11 , wherein the treatment device comprises a plurality of electrodes, and wherein the device icon comprises an identifier for each electrode of the plurality of electrodes.

18 . The non-transitory computer readable storage medium of claim 11 , wherein the operations further include
monitoring the real-time position of the treatment device catheter and updates, in real time, the interior map view based on the real-time position.

19 . The non-transitory computer readable storage medium of claim 11 , wherein the interior map view presents a view from a proximate end to a distal end or a view from the distal end to the proximate end.

20 . The non-transitory computer readable storage medium claim 11 , wherein the interior map view presents one or more lines at predetermined distances presenting depth.
