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 medical device may comprise a tube including: a proximal portion; and a distal portion having a slotted section with a plurality of slots formed therein. A proximalmost slot of the plurality of slots may have a first length in a circumferential direction about the tube. A distalmost slot of the plurality of slots may have a second length in the circumferential direction about the tube. The first length may be smaller than the second length. The medical device may further comprise a hub coupled to a proximal portion of the tube. Rotation of the hub may be configured to rotate the proximal portion of the tube about a longitudinal axis of the proximal portion of the tube.
