APPARATUSES AND METHODS FOR REGISTERING A REAL-TIME IMAGE FEED FROM AN IMAGING DEVICE TO A STEERABLE CATHETER

摘要

A method of registering a real-time image feed from an imaging device inserted into a steerable catheter using a navigation system is provided. The method includes inserting the imaging device into a working channel of the steerable catheter and generating a real-time image feed of one or more reference points, wherein the orientation of the reference points is known. The method further includes orienting a handle of the steerable catheter to a neutral position, displaying the real-time image feed on a display of the navigation system, and registering the real-time image feed to the steerable catheter by rotating the displayed image so that the reference points in the real-time image feed are matched to the known orientation of the reference points.

1. A method of registering a real-time image feed from an imaging device inserted into a steerable catheter using a navigation system comprising a display, wherein the steerable catheter comprises an elongate flexible shaft having a proximal end portion, a distal end portion terminating in a tip, a working channel extending therebetween, and a handle attached to the proximal end portion of the flexible shaft, the method comprising:
inserting the imaging device into the working channel of the steerable catheter; generating a real-time image feed of one or more reference points, wherein the orientation of the reference points is known; orienting the handle of the steerable catheter to a neutral position; displaying the real-time image feed on the display; and registering the real-time image feed to the steerable catheter by rotating the displayed image so that the reference points in the real-time image feed are matched to the known orientation of the reference points.
