Title:
IMPLANT FOR NON-LUMINAL AREA
Document Type and Number:
WIPO Patent Application WO/2020/196777
Kind Code:
A1
Abstract:
A non-luminal area implant with improved corrosion resistance, and a manufacturing method thereof are provided. (1) A magnesium alloy surface having a prescribed shape is fluorinated to form a fluorinated layer and a parylene layer is formed on the fluorinated layer to form this non-luminal area implant, which, on the magnesium alloy surface, has (a) a magnesium fluoride layer and (b) a parylene layer. (2) In a manufacturing method of this non-luminal area implant, (a) a magnesium alloy surface having an arbitrary shape is fluorinated to form a magnesium fluoride layer, and thereafter, (b) a para-xylylene resin is vapor deposited on the magnesium fluoride layer to form the parylene layer.
