Abstract

Methods, systems, and devices for marking the location of a biopsy are disclosed, including loading a navigation plan into a navigation system with the navigation plan including a CT volume generated from a plurality of CT images, inserting a probe into a patient's airways with the probe including a location sensor in operative communication with the navigation system, registering a sensed location of the probe with the CT volume of the navigation plan, selecting a target in the navigation plan, navigating the probe and location sensor to the target, storing a position of the location sensor in the navigation system as a biopsy location, and performing a biopsy at the stored biopsy location.

First claim

What is claimed is:

1 . A method for marking a biopsy location in a patient's airways, the method comprising:
loading a navigation plan into a navigation system, the navigation plan including a CT volume generated from a plurality of CT images; inserting a probe into a patient's airways, the probe including a location sensor in operative communication with the navigation system; registering a sensed location of the probe with the CT volume of the navigation plan; selecting a target in the navigation plan; navigating the probe and location sensor to the target; storing a position of the location sensor in the navigation system as a biopsy location; and performing a biopsy at the stored biopsy location.

2 . The method according to claim 1 , further comprising placing a virtual marker corresponding to the biopsy location in at least one of a 3D model of the patient's airways generated from the CT volume or a local view of the patient's airways generated from a slice of the CT volume.

3 . The method according to claim 1 further comprising inserting the probe through an extended working channel.

4 . The method of according to claim 3 , further comprising locking the probe relative to the extended working channel.

5 . The method of claim 4 , further comprising inserting the extended working channel and probe into a bronchoscope, and navigating them together to the target

6 . The method of claim 5 , further comprising locking the extended working channel in position at the target when the location sensor is navigated to the target.

7 . The method according to claim 5 , further comprising removing the probe from the extended working channel and inserting a biopsy tool through the extended working channel to the target to perform the biopsy.

8 . The method according to claim 1 , further comprising:
adjusting a position of the probe relative to the target, storing a second position of the location sensor in the navigation system as a second biopsy location, and performing a second biopsy at the second biopsy location.

9 . The method according to claim 1 , further comprising:
selecting a second target in the navigation plan; navigating the probe and location sensor to the second target; storing a second position of the location sensor in the navigation system as a second biopsy location; and performing a biopsy at the stored second biopsy location.

10 . The method according to claim 9 , further comprising providing tissue from at least one of the biopsy location or the second biopsy location for rapid on-site evaluation.

11 . The method according to claim 10 , further comprising:
receiving results from the rapid on-site evaluation clinician indicating a need to return to at least one of the biopsy location or the second biopsy location; presenting a pathway to at least one of the biopsy location or the second biopsy location as a return target in the navigation plan based on the rapid on-site evaluation; navigating the location sensor to the return target; storing a return position of the location sensor in the navigation system as a return biopsy location; and performing at least one of an additional biopsy or a treatment at the stored return biopsy location.

12 . The method according to claim 1 , further comprising storing a distance to a center of the target and a biopsy position number with the biopsy location.
