Abstract
The present invention relates generally a manufacturing process which results in a completely hydrogel polymer device that maintains lumen patency which allows for numerous applications. One or more physical post-implantation dimensions of the device can be controlled by placing it in a solution that has a predetermined osmolarity and/or pH. In addition, the device can deliver an absorbed therapeutic agent to a target anatomical site. Alternatively, the device can function as a selective membrane to selectively absorb one or more target molecules from a body fluid.
