Document Type and Number:
WIPO Patent Application WO/2018/113333
Kind Code:
A1
Abstract:
Disclosed are an artificial valvuloplasty ring (10) and a suturing method therefor. The artificial valvuloplasty ring (10) comprises a kernel tube (11), a flexible material layer (12) wrapping the kernel tube (11) and a fabric layer (13) wrapping the flexible material layer (12). The fabric layer (13) is in a closed-loop structure, and is provided with two end portions (131, 132) sutured by means of a suture thread. The two end portions (131, 132) are both provided with a plurality of ring-like structures (131A, 132A) arranged at intervals. The suture thread (18) successively passes through the ring-like structures (131A, 132A) of the two end portions (131, 132) alternately, thereby suturing the two ends. The fabric layer (13) of the artificial valvuloplasty ring (10) not only has a smaller impact on the blood flow speed, but also reduces the probability of a thrombus forming.
