Claim 9:
10. A device, comprising:
a flexible access cannula including a lumen extending therethrough, the flexible access cannula being sized and shaped to extend through a flexible endoscopic shaft to a target tissue within a living body;
a puncturing element sized and shaped to extend through the lumen of the access cannula and distally out a distal end of the access cannula;
a handle including a handle body and an advancement mechanism configured to advance 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;
a cap fixed to the puncturing element; and
a rotation hub fixed to the access cannula, the rotation hub having a living hinge that, in an extended position, resists longitudinal motion of the rotation hub relative to the handle body, the living hinge being depressible into a depressed position by a mechanism in the cap so that the rotation hub may move longitudinally relative to the handle body.
