Abstract
The present invention provides a hybrid stent for a blood vessel, the stent including: a plurality of first wires configured to form a plurality of rows in one direction and maintain the shape thereof inside a human body; a plurality of second wires configured to intersect the first wires and form a plurality of rows; and connectors configured to connect portions where the first wires and the second wires intersect each other; wherein a plurality of hollow holes are formed by the first wires and the second wires, and one or more of the plurality of second wires are degraded inside the human body after a predetermined period of time. Accordingly, the effect of enabling the stent to be easily removed can be expected because the second wires made of the biodegradable polymer are gradually degraded by body fluids.
