Abstract
A device includes an access cannula, a puncturing element, a handle. The access cannula includes a lumen extending therethrough. The access cannula is sized and shaped to extend through an endoscopic shaft to a target tissue within a living body. The puncturing element is sized and shaped to extend through the lumen of the access cannula and distally out a distal end of the access cannula. The handle includes a handle body and a mechanism for advancing the access cannula from a proximal position relative to the puncturing element, where a puncturing tip of the puncturing element is exposed distal to a distal end of the access cannula, to a distal position relative to the puncturing element, where the distal end of the access cannula covers the puncturing tip of the puncturing element.
