Abstract: A device includes a hollow needle with a lumen extending therethrough. The needle is sized and shaped to extend through an endoscopic shaft to a target tissue within a living body. The needle has a distal end with a sharpened distal tip for puncturing the target tissue and removing a portion of the tissue in the lumen. The device further includes a cylindrical stylet having a shaft sized and shaped to extend through the lumen of the needle and a distal end with a pointed distal tip for puncturing the target tissue. When the stylet is extended, the pointed distal tip of the stylet extends distally a predetermined distance past the sharpened distal tip of the needle.
