DEVICES, SYSTEMS, AND METHODS FOR NAVIGATING A BIOPSY TOOL TO A TARGET LOCATION AND OBTAINING A TISSUE SAMPLE USING THE SAME

摘要

A biopsy tool includes an elongated flexible body defining a distal end and a distal biopsy member disposed at the distal end of the elongated flexible body. The biopsy member incorporates a sensor assembly configured to enable detection of a location of the sensor assembly within a patient's airways. The biopsy member has a tissue-receiving portion defining a window and including first and second longitudinally-extending faces disposed on either side of the window. The faces are angled inwardly and towards one another to define an acute interior angle therebetween. Each face defines a sharpened cutting edge. The sharpened cutting edges are disposed on either side of the window. The faces are positioned such that the sharpened cutting edges increasingly approximate one another in the proximal-to-distal direction and culminate at an apex point.

1. A biopsy tool, comprising:
an elongated flexible body defining a distal end; a distal biopsy member disposed at the distal end of the elongated flexible body, the distal biopsy member incorporating a sensor assembly including at least one location sensor configured to enable detection of a location of the sensor assembly within a patient's airways, the distal biopsy member having a tissue-receiving portion defining a window and including first and second longitudinally-extending faces disposed on either side of the window, the faces angled inwardly and towards one another to define an acute interior angle therebetween, each face defining a sharpened cutting edge, the sharpened cutting edges disposed on either side of the window, the faces positioned such that the sharpened cutting edges increasingly approximate one another in the proximal-to-distal direction and culminate at an apex point.
