Composition for a hydrogel dilator article of manufacture and method for making same

摘要: Composition, article of manufacture, and a method for forming hydrogel dilation device use internal the human body. An aqueous monomer solution, appropriate cross-linking agents, catalysts are inserted into mold tube having predetermined contour shape. inert gas is forced through mixture contained in tube. The sealed by inserting plugs at opposing open ends. then polymerized keeping controlled temperature environment length time. A resulting moisture containing hydrogen rod extruded from Water soluble impurities removed dialysis distilled water. dried stream air until percentage rod. placed vacuum heated time particular substantially all removed. absorbant material may be before polymerization. extends external to after formation aids transmitting body fluids
