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.

Abstract: A clip for reducing a dimension of an opening in tissue may include a continuous member having a plurality of legs and a plurality of preformed bends connecting adjacent legs, wherein the plurality of legs form: a first group having two protrusions; a second group having two protrusions; and a third group having two protrusions, wherein each protrusion of each group includes two legs of the continuous member and a corresponding preformed bend connecting the two legs, and each protrusion of each group extends from a region adjacent a first end of the clip to a region adjacent a second end of the clip.
