Claim 11:
12. A device, comprising:
an access cannula including a lumen extending therethrough, the access cannula being sized and shaped to extend through an 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 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; and
a rotation hub fixed to the access cannula and coupled to a proximal end of the handle body, the rotation hub being rotatable relative to the handle body and slidable a first predetermined distance relative to the handle body, wherein the rotation hub includes a first proximal flange and a second distal flange with a shaft extending therebetween, the shaft having a washer and a first spring slidable thereover and constrained between the first and second flanges.
