Transplantation chamber, method for producing transplantation chamber, implantation device, and fusion method for porous membrane

摘要

INDUSTRIAL APPLICABILITY According to the present invention, there is provided a transplantation chamber and a method for producing the same, which has high durability, efficiently secures an internal space, and enables long-term maintenance of a biological constituent contained therein. A joint part in which one or more immunoisolation membranes are provided at the boundary between the inside and the outside of the chamber for use, and each of the immunoisolation membranes includes a porous membrane containing a polymer, and the porous membranes are directly fused to each other. And a porous membrane containing a polymer selected from polysulfone and polyethersulfone, wherein one part of the porous membrane is directly contacted with another part of the porous membrane. And a method for manufacturing an implanting chamber, which comprises heat-sealing the two directly contacted portions at a temperature not lower than the glass transition temperature and lower than the melting point of the polymer. It is provided.
