1. An implant assembly for a host tissue comprising:
- a first member including wall means that define a chamber for holding a second member, the wall means including a membrane defining an interface with the host tissue, the membrane having a conformation that results in growth of vascular structures by the host tissue close to the interface; and
a second member that is removably received in the first member and including a cavity having cells and a membrane having a structure that isolates the cells within the cavity from the immune response of the host.

Abstract
An implant assembly for a host tissue is provided. The implant assembly comprises a pouch including wall means defining a chamber for holding a second member, the wall means including an outer vascularizing membrane having a conformation that results in growth of vascular structures by the host tissue close to an interface between the vascularizing membrane and host tissue. The assembly includes a second member that can be removably inserted in the chamber including an interior for receiving cells and wall means defining an immuno-isolating membrane that isolates the cells from the immune response of the host tissue.
