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.

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 curled condition when in a fully deployed state, and the diameter of the lumen expands in response to an axial compression force applied when the penetrating member is proximally withdrawn from the lumen of the hollow central member, the proximal retention member having a first inner portion configured to run generally along a first inner surface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 reduces trauma 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 reduces trauma 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.

2. The central member of claim 1, wherein said central member is a stent.

3. The apparatus of claim 2 wherein the central member is adapted to permit the passage of the penetrating member adapted to penetrate tissue, and the distal retention member includes a first substantially straight leg member having first and second ends coupled to a distal portion of the central member at one end,

wherein said expansion from a first condition to an expanded condition comprises curling said substantially straight leg member radially to produce an increase in a distal radius of said leg member.

4. The apparatus of claim 3 wherein said proximal retention member can be expanded from a first condition to a second expanded condition having an increased radius,

the proximal retention member includes a first substantially straight leg member having first and second ends coupled to a proximal portion of the central member at one end, wherein said expansion from a first condition to a second expanded condition comprises curling said substantially straight leg member radially to produce an increase in a distal radius of said leg member.

6. The apparatus of claim 1, wherein the hollow central member comprise a mesh.

5. An apparatus to form an anastomosis between first and second luminal structures comprising:

a penetrating member;

a hollow central member having distal and proximal ends, said hollow central member being received over the penetrating member;

a distal anchor coupled to the distal end of said central member and adapted to be positioned in or about the second luminal structure after the penetrating member is advanced through a wall of the first luminal structure and a wall of the second luminal structure;

a proximal anchor coupled to the proximal end of said central member and adapted to be positioned in or about the first luminal structure after the penetrating member is advanced through the wall of the first luminal structure and the wall of the second luminal structure, the proximal anchor 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 reduces trauma to tissue of the first inner surface, the distal anchor 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 reduces trauma to tissue of the second inner surface; and

wherein the distal and proximal anchors are capable of assuming a curled condition when in a fully deployed state, moving toward each other, and approximating the two luminal structures, wherein a distal tip of the penetrating member is adapted to radially expand the hollow central member as said tip is drawn proximally through said member.

7. The apparatus of claim 5, wherein the curled proximal and distal anchors are configured to reduce trauma to tissue.
