Abstract

The present invention is directed to gastrointestinal or enteric (including biliary) anastomosis and the like. The anastomotic device of the invention i s a three dimensional woven tube (10) of wire preferably formed from a thermal , smart memory metal. The outer loops or ends (20) of the tube fold or loop ba ck on deployment in a manner which holds the luminal interface of the anastomot ic site into apposition at the deployment site. The women tube (10) is deployed using a canula (24) with a retractable outer sleeve (26).

Claims (5)

1. An anastomotic device for joining of lumens or hollow viscera which is adapted to be deployed at a luminal interface of two adjacent lumens , comprising a woven tube of wire with longitudinally spaced ends having an overlapping wire mesh design and having as unobstructed exterior end interior the tube being longitudinally extendable to cause the tube to become longer in length sad smaller is diameter, the tube being constructed from a thermal, shape memory alloy having circumferentially sparxd outer loops at each of the longitudinally spaced ends of the woven tube of was such that heat causes the tube to become larger is diameter sad to contract longitudinally and become axially compressed and flattened and the outer loops of the tube to deform and event after being inserted into holes of walls of the two adjacent lumens, the loops of the tube thermally deforming and evening to form petals is a manner directly opposed or interdigitated with each other which compresses and holds the walls of the two adjacent lemons in apposition, sufficient force being applied to the walls of the two adjacent lumens such that the holes between the two adjacent lumens are enlarged for drainage and leakage outside the two adjacent lumens is prevented.
2. The device of claim 1, wherein the thermal, shape memory alloy is a titanium-nickel alloy.
3. The device of claim 1, wherein the opposed petals ate interdigitated.
4. An anastomotic delivery device having a streamlined end, comprising a woven tube of wire with longitudinally spaced ends having an overlapping wire mesh design and having as unobstructed exterior and interior, the tube having circumferentially spaced outer loops at each of the longitudinally spaced ends of the woven tube of wire, a canula having as end designed to allow the tube to be slipped over the canula and pulled longitudinally causing the tuba to become longer in length and smaller is diameter, an outer sleeve adapted to be pushed ever the tube up to the streamlined end of the device thereby providing a smooth surface far inserting through walls of two adjacent lumens at a luminal interface in a body, and subsequently retracted, a wire having a tip, initially retracted in the canula, and adapted to be exposed at the tip to create holes in the walls of the two adjacent lumens to assist a surgeon when passing the device through the walls of the lumens, the tube being constructed from a thermal, shape memory alloy such that when the sleeve is retracted heat from the body causes the tube to become larger in diameter and to contract longitudinally and become axially compressed and flattened and causes the outer loops of the tube to deform and evert to foam petals in a manner directly opposed or interdigitated with each other which compresses and holds the walls of the two adjacent lumens in apposition, sufficient force being applied to the walls of the two adjacent lumens such that the holes between the two adjacent lumens are enlarged for drainage and leakage outside the two adjacent lumens is prevented.
5. The device of claim 4, wherein the thermal, shape memory alloy is a titanium-nickel alloy.

7. The device of claim 4, wherein tire opposed petals are interdigitated.

13. The device of claim 4, wherein the streamlined end is moveable in a direction opposed to the retractable sleeve when the sleeve is retracted to expose both of the longitudinally spaced ends of the woven tube of wire to the body heat.
