Title (EN) ABSORBABLE STENT
(FR) STENT ABSORBABLE
(ZH) 可吸收支架
Abstract:
(EN) An absorbable stent (100) comprises an absorbable matrix. The matrix comprises a plurality of wave-shaped rings (01) connected by means of connection units (02) and arranged in an axial direction. The wave-shaped ring (01) comprises a plurality of waves (011) arranged in a circumferential direction. A peak (A), a valley (C) and a support (B) connecting the peak (A) and the valley (C) constitute the wave (011). Two adjacent wave-shaped rings (01) and the connection unit (02) form a closed side supporting unit (03). The matrix has a volume of [4, 40] μm per unit blood vessel area. The absorbable stent (100) has sufficient radial supporting strength for clinical application. Moreover, the volume of the matrix per unit blood vessel area is less than volumes of existing stents. When the absorbable stent (100) and existing stents are made of the same material, the absorbable stent (100) has a shorter degradation and absorption cycle.
(FR) L'invention concerne un stent absorbable (100) comprend une matrice absorbable. La matrice comprend une pluralité de bagues en forme d'onde (01) reliées au moyen d'unités de connexion (02) et agencées dans une direction axiale. La bague en forme d'onde (01) comprend une pluralité d'ondes (011) agencées dans une direction circonférentielle. Un pic (A), un creux (C) et un support (B) reliant le pic (A) et le creux (C) constituent l'onde (011). Deux bagues en forme d'onde (01) adjacents et l'unité de connexion (02) forment une unité de support (03) côté fermé. La matrice a un volume de [4, 40] μm par unité de surface de vaisseau sanguin. Le stent absorbable (100) a une force de support radiale suffisante pour une application clinique. De plus, le volume de la matrice par unité de surface de vaisseau sanguin est inférieur à des volumes de stents existants. Lorsque le stent absorbable (100) et les stents existants sont constitués du même matériau, le stent absorbable (100) a un cycle de dégradation et d'absorption plus court.
(ZH) 一种可吸收支架(100),包括可吸收基体。基体包括多圈通过连接单元(02)连接且轴向排列的波圈(01),波圈(01)由多个周向排列的波形(011)组成。波形(011)由波峰(A)、波谷(C)和连接波峰(A)与波谷(C)的支撑杆(B)组成。相邻的两个波圈(01)与连接单元(02)形成封闭的侧支单元(03)。单位血管面积的基体的体积为[4,40]μm。这种可吸收支架(100)的径向支撑强度能够满足临床应用、且单位血管面积的基体的体积比现有支架的更低。使用相同材料时,这种可吸收支架(100)相对现有支架具有更短的腐蚀和吸收周期。
