摘要:
Medical methods and devices for treating aortic dissections. A catheter-based cutting device permits cutting a septum of acute or chronic aortic dissections, in a retrograde manner. The catheter includes a base section having a central lumen therethrough, two flexible arms extending from a distal end thereof, where each arm has a channel therethrough for a passage of a guide wire. With distal ends of the two flexible arms separated, the two arms form a Y-shape with the base section. With distal ends of the two flexible arms together, the two arms have a longitudinal profile, about a periphery thereof, identical to a longitudinal profile of the base section. A non-mechanically actuated cutting component resides between the two arms in a vicinity of the distal end of the base section. The cutting component faces distally outward between the two arms with the distal ends of the two flexible arms separated.
摘要(中):
用于治疗主动脉夹层的医疗方法和装置。 基于导管的切割装置允许以逆行的方式切割急性或慢性主动脉夹层的隔膜。 该导管包括具有穿过其中的中央内腔的基部,从其远端延伸的两个柔性臂,其中每个臂具有穿过其中的用于导丝通道的通道。 两个柔性臂的远端分开时,两个臂与基部形成Y形。 通过两个柔性臂的远端在一起,两个臂具有围绕其外周的纵向轮廓,其与基部的纵向轮廓相同。 非机械致动的切割部件位于基部的远端附近的两个臂之间。 切割部件朝向两个臂之间的远端向外,两个柔性臂的远端分开。 p>
