Abstract

The present disclosure relates to implantable encapsulation devices for housing a biological moiety or a therapeutic device that contains a biological moiety. Particularly, aspects of the present disclosure are directed to an implantable apparatus that includes a distal end, a proximal end, a manifold including at least one access port positioned either at the distal end or the proximal end, and a plurality of containment tubes affixed to the manifold and in fluid communication with the at least one access port. Additionally, the encapsulation device may contain a flush port and a tube that are fluidly connected to the manifold. The containment tubes may contain therein a biological moiety (e.g., cells) or a therapeutic device (e.g. a cell encapsulation member).
