  • Publication number: 20150265257
    Abstract: A system for performing a surgical procedure includes a bronchoscope, monitoring equipment coupled to the bronchoscope, a tracking system, a positioning assembly, and a biopsy tool. The biopsy tool includes an elongated flexible body extending from a proximal end to a distal end and a biopsy member formed on the distal end of the elongated flexible body. The biopsy member includes a tissue-receiving portion defining an opening including sharpened edges. The sharpened edges are disposed on the interior perimeter of the opening and are capable of cutting tissue. A biopsy tool is also provided.

  • Publication number: 20150141869
    Abstract: A biopsy tool includes an elongated flexible body, a sensor assembly, and a screw member. The sensor assembly is disposed within the elongated flexible body towards the distal end thereof. The sensor assembly includes a location sensor(s) configured to enable detection of a location of the sensor assembly. The screw member is coupled to the distal end of elongated flexible body, extends distally from the elongated flexible body, and is positioned distally of the sensor assembly. The screw member defines a helical configuration having a hollow interior and is configured for simultaneous rotation relative to tissue and advancement into tissue to obtain a tissue sample.

  • Publication number: 20150141809
    Abstract: 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.
