Method and apparatus for guiding an instrument to a target in the lung
First Claim
1. An apparatus for guiding a medical instrument to a target in a lung of a patient, wherein one or more positions of a tracked navigation instrument within the lung are sampled and used to produce a display of the tracked navigation instrument in the lung, the apparatus comprising:
- a lumen for insertion into the lung;
a tracked navigation instrument for insertion into the lung through the interior of the lumen, wherein a tip of the tracked navigation instrument is advanced to the target using the display of the tracked navigation instrument in the lung, and wherein the lumen is advanced over the tracked navigation instrument to the target; and
a medical instrument for insertion through the lumen to the target.

Abstract
The invention provides methods and apparatus for navigating a medical instrument to a target in the lung. In one embodiment, the invention includes inserting a bronchoscope into the lung, inserting a catheter into the lung through the working channel of the bronchoscope, inserting a tracked navigation instrument wire into the lung through the catheter, navigating the tracked navigation instrument through the lung to the target, advancing the catheter over the tracked navigation instrument to the target, removing the tracked navigation instrument from the catheter, and inserting a medical instrument into the catheter, thus bringing the medical instrument in proximity to the target.

26. A method for guiding a medical instrument to a target in a lung of a patient, the method comprising:
-
performing a registration of the lung using at least one image of the lung and position information regarding one or more positioning indicating elements within the lung;
inserting a bronchoscope having a working channel into the lung;
verifying the registration;
inserting a catheter into the lung through the working channel of the bronchoscope;
inserting a tracked navigation instrument into the lung though the catheter;
navigating the tracked navigation instrument to the target using a display of the tracked navigation instrument within the lung relative to the target on the at least one image of the lung;
advancing the catheter over the tracked guidewire to the target;
navigating the medical instrument to the target through the catheter.
