Abstract:
1. An endoscopic needle device, comprising: a catheter having a proximal end and a distal end and a lumen extending therethrough; a needle at least partially disposed within the lumen and selectively movable between a needle retracted position and a needle extended position; a stabilization mechanism for holding tissue at an injection site while simultaneously penetrating the tissue at the injection site with the needle; and means for connecting the needle and the stabilization mechanism, wherein movement of the needle or the stabilization mechanism over at least a part of a range of movement in a first direction causes the other of the needle or the stabilization mechanism to move in a second direction opposite to the first direction; wherein the needle and stabilization mechanism are adapted such that both the needle and the stabilization mechanism may simultaneously extend distal to the distal end of the catheter.
