Title:
BIODEGRADABLE STENT AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/240255
Kind Code:
A1
Abstract:
The present invention relates to a biodegradable stent comprising: a stent material including biodegradable polymers; and a contrast medium containing iodine components and applied on the stent material. The stent according to the present invention is removed by being absorbed in the human body after a certain period of time, and thus has excellent biodegradability. Also, the stent has improved radiopacity via the iodine contrast medium coating and exhibits high imaging contrast even when a medical procedure is performed while performing radiography in real time, and thus is highly efficient. In addition, the stent can be useful when inserted into a small diameter blood vessel, an acute obstructive lesion, an imminent obstructive lesion, or the like due to having a low axial contraction rate and high flexibility, radial strength, and elastic restorability.
