The DynamX Bioadaptor (Elixir Medical Corporation) is a novel coronary artery scaffold consisting of 3 helical strands connected by a bioabsorbable polymer. After 6 months, the polymer dissolves, restoring the physiological motion of the coronary artery as the interconnected (caged) structure of the scaffold disengages. Here we report the cases of 2 patients treated with the Bioadaptor who underwent intravascular imaging at the time of the index procedure and during follow-up periods of 30 and 36 months, respectively. The cross-sectional images of the scaffold were analyzed and compared with those obtained during the index procedure. At follow-up, the mean cross-sectional area of the scaffold was increased significantly in both cases, regardless of the degree of intimal hyperplasia. Such unique properties of the Bioadaptor make it a promising alternative to contemporary drug-eluting stents.
DynamX生物适配器（Elixir医疗公司）是一种新型冠状动脉支架，由3条螺旋线组成，通过生物可吸收聚合物连接。6个月后，聚合物溶解，随着支架相互连接（笼状）结构分离，冠状动脉的生理运动得以恢复。在此，我们报告2例接受生物适配器治疗的患者病例，这2例患者在初次手术时以及分别在30个月和36个月的随访期内接受了血管内成像检查。对支架的横截面图像进行了分析，并与初次手术时获得的图像进行了比较。随访时，无论内膜增生程度如何，两例患者支架的平均横截面积均显著增加。生物适配器的这种独特特性使其成为当代药物洗脱支架的一个有前景的替代方案。
