BIOCOMPATIBLE, THERAPEUTIC, IMPLANTABLE DEVICE

摘要

This invention relates to an implantable, biocompatible device possessing at least one cavity within which live cells can be introduced and maintained such that when the device is implanted into a subject, the cells are in continuous interaction with the subject's bodily fluids to provide a therapeutic or prophylactic effect to the subject that requires a direct interactive contact with the body's fluids, wherein at least one portion of the outside thereof comprises a non-porous, semi-permeable, biocompatible film formed from a copolymer comprising about 5 to 45 wt % of at least one hard segment, and about 95 to 55 wt % of at least one soft segment, substantially impermeable to cells and particulate matter. Multiple embodiments of the device of this invention are provided.
