Method for implanting tissue in a host
First Claim

1. A method for implanting cells into a host tissue comprising the steps of:
- implanting an implant assembly for holding cells including wall means for forming a porous boundary between the host tissue and the implanted cells in the device, the pore size of the boundary being sufficient to isolate the implanted cells from the immune response, the assembly being implanted without the cells into a host tissue;
allowing the assembly to be prevascularized; and
adding to an interior of the assembly the cells by use of a cannula, by inserting the cannula from a first end of the chamber to a position near a second end of the chamber and adding cells to the chamber as the cannula is removed therefrom.

Abstract
A method for implanting cells into a host tissue is provided. The method comprises the steps of: creating an implant assembly for holding cells including wall means for forming a porous boundary between the host tissue and the implanted cells in the device, the pore size of the boundary being sufficient to isolate the implanted cells from the immune response; implanting the assembly without the cells into a host tissue; and accessing an interior of the assembly to add the cells thereto.

2. A method for implanting select therapeutic cells in a host tissue comprising the steps of:
-
implanting an implant assembly including wall means having an interior surface defining a chamber for holding select therapeutic cells for implantation and an exterior surface defining an interface with the host tissue, the exterior surface having a confirmation that results in growth of vascular structures by the host tissue close to the interface, the assembly being implanted in host tissue without the select therapeutic cells; and adding, after implantation, to the assembly the select therapeutic cells using a cannula, by inserting the cannula into the chamber for an entire length of same and adding select therapeutic cells to the chamber as the cannula is removed therefrom.
