摘要:
An intragastric balloon with a 12-month lifespan. The intragastric balloon has a shell made of a material with as good as or better than initial mechanical properties of previous materials; i.e. higher ultimate tensile strength (UTS) and elongation at break (Eb), lower stiffness (K), higher acid stability, and improved resistance to infection. The new materials in particular provide improved acid resistance. These new materials produce a device that has reduced adverse events and a longer lifespan in vivo. The materials may form the entire wall of the shell or may form just a barrier layer coupled with a scaffold layer of a different material.
