Abstract
A stent device including a stent cover having differing porosity ratio is disclosed. The stent covers the stent body comprising of stent wires and stent cells enclosed by the stent wires. The stent cover differs in porosity ratio for areas covering the stent wires and the areas covering the stent cells. The porosity ratio for areas covering the stent wires may have a higher porosity rate in order to promote endothelialization of the stent device. A bilayer stent cover differing in porosity ratio may be used to cover the stent body, as well as stent cover not covering the entirety of the stent body.
