Abstract

The present invention relates to a device 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 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.

Claims

1. A system to form a fluid pathway between a first and a second hollow body comprising:

a penetrating member;

a hollow central member forming a lumen received over the penetrating member and having distal and proximal end portions, a length, and a diameter;

a distal retention member coupled to the distal end portion and a proximal retention member coupled to the proximal end portion, the distal retention member adapted to anchor inside the second hollow body and the proximal retention member adapted to anchor inside the first hollow body, such that the length of the central member decreases, the distal and proximal retention members assume a condition when in a fully deployed state, the proximal retention member having a first inner portion configured to run generally along a first inner surface of the first hollow body, a first outer portion spaced apart from the first inner portion and the first inner surface when in the fully deployed state, and a first intermediate portion spanning between the first inner portion and the first outer portion generally transverse to the first inner surface, the configuration of the first inner portion, the first outer portion and the first intermediate portion thereby presenting an anchor interface with the first inner surface that to tissue of the first inner surface, the distal retention member having a second inner portion configured to run generally along a second inner surface of the second hollow body, a second outer portion spaced apart from the second inner portion and the second inner surface when in the fully deployed state, and a second intermediate portion spanning between the second inner portion and the second outer portion generally transverse to the second inner surface, the configuration of the second inner portion, the second outer portion and the second intermediate portion thereby presenting an anchor interface with the second inner surface that to tissue of the second inner surface, the first and second hollow bodies being drawn toward each other by the first and second inner portions pushing against the first and second inner surfaces, respectively.
