Abstract
An endoscopic needle device having a handle and a catheter sheath connected to the handle, wherein the catheter sheath has at least one lumen, for example a needle lumnen and a stabilization lumen, extending there through. A needle is selectively movable within the needle lumen between a needle retracted position and a needle extended position and a stabilization element is selectively movable within the stabilization lumen between a stabilizer retracted position and a stabilizer extended position. A linking mechanism may operatively connect the needle and the stabilization element so that when the needle is in the needle retracted position the stabilization element is in the stabilizer extended position and when the needle is in the needle extended position the stabilization element is in the stabilizer retracted position.
