Abstract
A stent for repairing post-anastomasis (e.g., bariatric) surgery leaks is formed by an elongated tube having a proximal flare-shaped flange, an enlarged middle section, and a distal flare-shaped flange, where an exterior surface of the elongated tube is substantially covered with a polymer.
Claims20
A method of manufacturing a stent, comprising:
- forming a stent having a bulge around a mandrel;
- and
- removing the mandrel from an interior of the stent;
- wherein the step of forming the stent having the bulge around the mandrel includes moving a first end portion of the mandrel toward a second end portion of the mandrel to radially displace a middle region of the stent.
1 more element
A method of manufacturing a stent, comprising:
- braiding a plurality of filaments into a braided tubular member around a mandrel, the mandrel having a first end region, a second end region opposite the first end region, and a middle region between the first end region and the second end region, the braided tubular member having a first outer diameter along the first end region, a second outer diameter along the second end region, and a third outer diameter along the middle region, the third outer diameter being greater than the first and second outer diameters;
- and
- removing the braided tubular member from the mandrel;
- wherein the third outer diameter of the braided tubular member is formed by moving the first end region toward the second end region.
1 more element
A method of manufacturing a stent, comprising:
- positioning a stent around a mandrel;
- moving a first end of the mandrel toward a second end of the mandrel to cause a middle region of the stent to radially expand to form a bulge in the middle region of the stent;
- heat treating the stent with the bulge;
- and
- thereafter, removing the mandrel from an interior of the stent.
