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.
Claims12
A method for manufacturing a medical device, comprising:
- depositing an inner layer material comprising a hydrogel on a rotating, horizontally-disposed mandrel;
- coagulating the inner layer material comprising the hydrogel in place on the mandrel;
- dehydrating the inner layer material;
- depositing a second layer of material comprising a hydrogel on the inner layer material such that the medical device is produced without thermoplastic processing;
- and
- placing the medical device in a solution having a predetermined osmolarity.
