An implantable containment apparatus for receiving and retaining a plurality of cells for insertion into a patient, such as into a tissue bed, is disclosed. The device includes a chamber having structural spacers therein to maintain an average distance between the first interior surface and the second interior surface of the chamber and to define at least one reservoir space for the placement of cells within the chamber.

Polytetrafluoroethylene (PTFE) composite articles that have a macro textured surface. The composite articles include at least two different PTFE membranes in a layered or stacked configuration. The composite article has a macro textured surface characterized by a plurality of strands raised from the surface of the PTFE membrane. The strands may be formed of either interconnected nodes of PTFE or of at least one nodal mass of PTFE and have a length equal to or greater than about 1.5 mm. The macro textured surface provides a topography to the first PTFE membrane. The composite articles have a bubble point from about 3.0 psi to about 200 psi, a thickness from about 0.01 to about 3.0 mm, and a bulk density from about 0.01 g/cmto about 1.0 g/cm.
