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.
