STENT WITH IMPROVED RESISTANCE TO MIGRATION

摘要

A modular mating stent is adapted to resist migration within a receiving stent. The modular mating stent has a substantially self-expandable first section of predetermined compressibility that is adapted to permit the first section to conform to the shape of a body lumen surrounding the first section. The modular mating stent also has a balloon-expandable second section that is less compressible than the first section, which is adapted to firmly engage a surface of the receiving stent surrounding the second section.
