Problems solved by technology

thus, such observation accessories are limited in their ability to reach target organizations
second, such systems do not provide location information that facilitates guidance to target organizations
Finally, such devices are of little or no use for guiding a medical device to a target location
If this observation accessory is removed to introduce the instrument into the working path, then it will inevitably make the manipulation of the instrument "blind" again, unable to ensure that the correct target tissue is reached

Embodiment Construction

[0110] The present invention provides endoscopic structures and corresponding techniques for navigating into a target in branched tissue such as the human lung and bringing a medical device to the target.

[0111] The operation and principles of the endoscope and guidance techniques of the present invention may be better understood with reference to the drawings and accompanying descriptions.

[0112] Before proceeding directly to the drawings, it is advantageous to understand that the present invention provides a system and corresponding method which include a number of features, each of which is believed to be patentable in its own right, except as stated herein Beyond what is described, many of these features may have utility independent of some other feature of the invention in context. For the sake of clarity, and to illustrate the synergy between the different aspects of the invention when combined, the different features will be described in the context of the combined ...

Abstract

Systems and methods employing a small guage steerable catheter (30) including a locatable guide (32) with a sheath (40), particularly as an enhancement to a bronchoscope (14). A typical procedure is as follows. The location of a target in a reference coordinate system is detected or imported. The catheter (30) is navigated to the target which tracking the distal tip (34) of the guide (32) in the reference coordinate system. Insertion of the catheter is typically via a working channel of a convention bronchoscope. Once the tip of the catheter is positioned at the target, the guide (32) is withdrawn, leaving the sheath (40) secured in place. The sheath (40) is then used as a guide channel to direct a medical tool to target.

Description

technical field [0001] The present invention relates to endoscopes, and more particularly to endoscopic structures and techniques for navigating to a target in branched structures such as the human lung and bringing a medical device to the target. Background technique [0002] Typically, a biopsy of suspiciously malignant tissue is taken from inside the bronchial tree using a bronchoscope. A bronchoscope is an endoscope, which is a flexible tube with a tiny camera at the end. By actuation of a handle at the proximal end of the bronchoscope, the tip of the bronchoscope can be deflected in two opposite directions so that the bronchoscope can be introduced inside the bronchial tree. Such bronchoscopes also have a working channel with an internal diameter of typically about 2.8 mm, allowing an instrument such as biopsy forceps to be inserted and actuated forward of the end of the bronchoscope. [0003] Once an unidentified lung mass is found on a CT scan, the lung mass should ...
