Abstract
A bioptic device of the cannula and internal stylet type wherein the stylet includes a sharp tip with a gutter adjacent to the tip for obtaining a tissue sample within a larger body of tissue. The cannula, stylet tip, and gutter bear threading to better enable the bioptic device to fix tissue when the bioptic device is rotationally advanced within the body of tissue. The cannula and stylet may additionally bear complementary threading to ensure that they can only be rotationally actuated with respect to each other.
