APPARATUSES AND METHODS FOR ENDOBRONCHIAL NAVIGATION TO AND CONFIRMATION OF THE LOCATION OF A TARGET TISSUE AND PERCUTANEOUS INTERCEPTION OF THE TARGET TISSUE

摘要

A method of confirming the location of a target tissue within a patient using a navigation system is provided. The navigation system displays images from a pre-acquired image dataset and provides location information of a medical device within a patient in relation to a patient tracking device affixed to the patient. The method includes determining an initial location of the target tissue, navigating a steerable catheter through the airway of the patient to a position proximate the initial location, tracking the location of the steerable catheter in the airway using the navigation system, generating information regarding the presence of the target tissue using a tissue sensing device inserted into the steerable catheter, and determining a confirmed location of the target tissue in relation to the patient tracking device using the generated information regarding the presence of the target tissue and the tracked location of the steerable catheter.

主权项

1. A method of confirming the location of a target tissue within a patient using a navigation system, the navigation system comprising a localization device, an electromagnetic field generator, a display, and a pre-acquired image dataset of an airway of the patient, the navigation system being adapted to display images from the image dataset and to provide location information of a medical device within the patient in relation to a patient tracking device comprising a plurality of localization elements, the method comprising:
affixing the patient tracking device to an external surface of the patient; tracking the location of the patient tracking device using the navigation system; displaying an image from the image dataset on the display, wherein the displayed image is registered to the patient tracking device; determining an initial location of the target tissue in the image dataset; navigating a steerable catheter through the airway of the patient to a position proximate the initial location, the steerable catheter having a proximal end portion and a distal end portion terminating in a tip, a working channel extending there between, and a localization element disposed proximate the distal end portion thereof; tracking the location of the localization element of the steerable catheter in the airway using the navigation system; generating information regarding the presence of the target tissue using a tissue sensing device inserted into the working channel of the steerable catheter; determining a confirmed location of the target tissue in relation to the patient tracking device using the generated information regarding the presence of the target tissue and the tracked location of the localization element; recording the confirmed location of the target tissue; and displaying the confirmed location of the target tissue on the display of the navigation system in an image from the image dataset.
