1. An implantable combination comprisinga) a barrier (12);
- andb) a macromolecular bio-compatible material (14);
characterized in thatthe barrier (12) is porous to allow moieties of the macromolecular bio-compatible material (14), when implanted, to be exposed on and/or through the barrier, whereby the surface of the barrier is experienced by the body as an essentially non-foreign object.

Abstract
The invention relates to an implantable combination comprising a barrier (12), and a macromolecular bio-compatible material (14). The barrier (12) is porous to allow moieties of the macromolecular bio-compatible material (14), when implanted, to be exposed through the barrier, whereby the surface of the barrier is experienced by the body as an essentially non-foreign object. It also relates to an implant made from a barrier material and a bio-compatible material, the implant being suitable as e.g. a breast implant.

- and
- 16. An implant comprising a macromolecular bio-compatible material, enclosed in a pouch made of a barrier material which is porous to allow moieties of the hydrogel, when implanted, to be exposed through the barrier, whereby the surface of the barrier is experienced by the body as an essentially non-foreign object.
-
19. A depot device, for sustained or controlled release of a drug or other beneficial agent, comprising
a) a barrier; -
b) a macromolecular and bio-compatible material; c) a drug distributed in the macromolecular and bio-compatible material; wherein the barrier material is porous to allow moieties of the macromolecular and bio-compatible material, when implanted, to be exposed through the barrier, whereby the surface of the barrier is experienced by the body as an essentially non-foreign object, and to allow the drug to be released through the barrier.
