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.
Claims30
A medical device comprising:
- an inner layer including a coagulated hydrogel polymer material defining a lumen of the medical device;
- and
- one or more additional layers encircling the inner layer, a first of the one or more additional layers including a coagulated hydrogel polymer material fused with the underlying coagulated hydrogel polymer material of the inner layer at an interface;
- the interface having a structural configuration corresponding to the hydrogel polymer material of the inner layer in a dehydrated state fused to the coagulated hydrogel polymer material of the first additional layer in a solvated state;
- wherein the coagulated hydrogel polymer material of the inner layer and the coagulated hydrogel polymer material of the first of the one or more additional layers encircling the inner layer are structurally stable so that the medical device does not require a substrate or scaffold to maintain its mechanical characteristics.
