PVA Microspheres ( Dead Block) Bead Block PVA Microspheres 为生物相容性聚乙烯醇水凝胶(biocompatible polyvinyl alcohol hydrogel)制作的非吸收性栓塞微粒,球形,可变形压缩。微球的颜色为蓝色,经微导管注射容易,经过精确校准的直径。不同的颜色...
Tris-Acryl Microspheres,或 embosphere。原Biosphere Medical 生产,现为Merit 收购。 Embosphere Embosphere 微粒的弹力特性,允许被暂时压缩到33%,所以存在通过导管的最小直径。 Tris-Acryl Microspheres 被压缩的Tris-Acryl Microspheres 导管直径 (in...

为什么需要球形栓塞微粒? 这是因为非球形栓塞微粒直径不一,形态不规则。在经导管注射栓塞血管的过程中容易发生凝聚,即在导管或血管中发生嵌顿,导致微粒在血管中发生拥塞,不能预期微粒栓塞的水平,导致栓塞效率下降。而球形栓塞微粒是PVA等非球形栓塞微...
