Abstract
A device is provided for endoscopy or endosonography- guided transluminal interventions whereby two luminal structures in the body may be drawn toward each other and a fluid conduit formed in between. The device may have a penetrating member and a hollow central member to which is coupled a distal retention member and in one embodiment a proximal retention member. The retention members may each be positioned inside one of the luminal structures and expanded from a first condition to an expanded second condition having an increased radius. The length of the central member may be shortened and its diameter expanded to approximate the two retention members and thereby the luminal structures.
