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 system for treating tissue includes a first fastener including a first anchoring element at a distal end thereof for anchoring the first fastener in a first target portion of tissue extending about a periphery of a tissue defect to be treated and a first suture extending from a proximal end thereof. The system also includes a second fastener including a second anchoring element at a distal end thereof for anchoring the second fastener in a second target portion of tissue extending about a periphery of a tissue defect to be treated and a second suture extending from a proximal end thereof. Furthermore, the system includes a cinch element disposed about both of the first and second sutures and slidable therealong such that a tension applied to the first and second sutures draws the first and second fasteners toward one another to close the tissue defect.
