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.

Abstract: A medical device may comprise a tube including: a proximal portion; and a distal portion having a slotted section with a plurality of slots formed therein. A proximalmost slot of the plurality of slots may have a first length in a circumferential direction about the tube. A distalmost slot of the plurality of slots may have a second length in the circumferential direction about the tube. The first length may be smaller than the second length. The medical device may further comprise a hub coupled to a proximal portion of the tube. Rotation of the hub may be configured to rotate the proximal portion of the tube about a longitudinal axis of the proximal portion of the tube.
