An implantable device for encapsulating cells includes one or more cell encapsulation layers. Each of the cell encapsulation layers includes a first membrane that is semipermeable, a second membrane that is semipermeable, and a first plurality of weld lines. The second membrane is attached to the first membrane by the first plurality of weld lines. The first membrane, the second membrane, and the first plurality of weld lines define at least one cell channel for encapsulating cells. The cell encapsulation device is configurable between a collapsed configuration and an inflated configuration.

A cell encapsulation device for implantation in a body includes one or more cell encapsulation layers, each of the one or more cell encapsulation layers including at least one membrane and a guide tube. The at least one membrane is semipermeable. The least one membrane forms a chamber for encapsulating cells and at least one access port through the at least one membrane. The guide tube extends into the chamber from the at least one access port. The guide tube includes a porous wall along at least a portion of its length. The guide tube is capable of guiding movement of a catheter within the chamber.
