Sheath system for improving the efficiency of lower limb arterial occlusion recanalization

By using a combination of an adjustable-bend sheath and a channel to construct a balloon in minimally invasive interventional surgery, the problem of guidewire entry into the true lumen was solved, improving the efficiency of lower extremity arterial occlusion recanalization and ensuring the safety and controllability of the procedure.

Abstract

一种提高下肢动脉闭塞开通效率的鞘管系统，其包括鞘管及多个通道构建球囊。鞘管包括远端端部的可调弯段，可调弯段为锥度段，方便引导鞘管前移；通道构建球囊设置在鞘管远端靠近可调弯段的位置；通道构建球囊用于在假腔与闭塞段终止位置扩张假腔，通过可控的扩张实现内膜的安全突破，构建出鞘管自假腔进入真腔的通道；设置多个通道构建球囊，以保证根据需要逐渐对假腔进行扩张，最大程度地避免过度突破。通过可调弯段及多个通道构建球囊的配合，当内膜较薄时直接通过弯曲可调弯段完成突破构建通道，当内膜较厚时通过多个通道构建球囊配合完成内膜突破的通道构建，使得该器械可以满足各种情况的假腔到真腔的通道构建，提高闭塞开通效率。
