Automated Surgical Navigation with Electro-Anatomical and Pre-Operative Image Data
First Claim
1. A method for navigating a medical device within a subject'"'"'s body with a magnetic navigation system and an electromagnetic localization system, the method comprising:
- importing a pre-operative three-dimensional data set of an anatomical surface within the subject'"'"'s body into a localization system for monitoring spatial location of the medical device;
applying one or more navigational control parameters to the magnetic navigation system for driving the medical device relative to the pre-operative anatomical surface to one or more points of contact with the actual anatomical surface within the subject'"'"'s body;
creating a geometric anatomical map from the three-dimensional location and sensed electrical activity associated with each of the one or more points of contact;
registering the geometric anatomical map with the pre-operative anatomical surface data;
selecting at least one other desired location from the pre-operative anatomical surface and using localization system data to provide location data to the magnetic navigation system for driving the medical device to the at least one other desired location; and
updating the geometric anatomical map to include the location data and sensed electrical activity associated with the at least one other desired location.

Abstract
A method for navigating a medical device to an anatomical surface within a subject to perform electro-anatomical mapping using a magnetic navigation system is provided that includes importing a pre-operative image data set of an anatomical surface in the subject'"'"'s body into a localization system. One or more control parameters are applied to the magnetic navigation system to drive the medical device to one or more points of tissue contact, from the locations of which a geometric anatomical map can be created and registered with the pre-operative anatomical image. The pre-operative anatomical surface image and a representation of the geometric anatomical map are displayed relative to one another, such that a user may select a location on the displayed pre-operative anatomical image to navigate the medical device towards. The localization system provides the location data to the magnetic navigation system to drive the medical device to the desired location, for enabling further electrophysiology mapping or ablation treatment.
