Title:
CAROTID ARTERY 3D PRINTING DEGRADABLE STENT
Document Type and Number:
WIPO Patent Application WO/2023/178937
Kind Code:
A1
Abstract:
Disclosed is a carotid artery 3D-printed degradable stent, comprising a supporting block, a supporting rod, and a connecting rod. The supporting rod is arranged in the supporting block, and the connecting rod is fixed to the side of the supporting block; the supporting block comprises a movable cavity formed in the supporting block, a plurality of first latches are fixed to an inner wall of the movable cavity, and a through hole is formed on the surface of the supporting block; the supporting rod comprises a plurality of second latches fixed to the surface of the supporting rod. The present invention provides support for a diseased blood vessel immediately after implantation, and effectively inhibits restenosis. Meanwhile, in the degradation process, a drug in a drug storage cavity can carry out staged treatment on the blood vessel, the therapeutic effect is improved, and after the blood vessel is repaired, the stent is directly and completely degraded, and the normal physiological function of the blood vessel is recovered. By means of the supporting block, the supporting rod, and the connecting rod, after being expanded by a balloon, the supporting block and the supporting rod are subjected to plastic deformation, so that the blood vessel wall is expanded and the expanded state is maintained, thereby enabling blood circulation to be smooth.
