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. Catheters and stents are particular examples, and their composition, mechanical characteristics, and the significantly unique ability to conduct and allow fluids to pass from one end to the other without physiological rejection, inflammation, or manifestation of complications due to implant or otherwise undesirable outcomes when used for ambulatory and or therapeutic interventions is the purpose of the invention.
