Protective sheath assembly for a polymer scaffold

用于聚合物骨架的保护性鞘组件

Abstract

医疗装置包含卷曲至具有扩展球囊之导管的聚合物骨架。在卷曲之后,在卷曲的骨架外放置鞘,以在将骨架递送至体内的靶点时,减小卷曲的聚合物骨架的回弹并且保持赖以将骨架保持至球囊的骨架-球囊接合。该鞘由医疗专业人员通过直接移除鞘或者利用包含导管的管来移除。
A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. A sheath is placed over the crimped scaffold after crimping to reduce recoil of the crimped polymer scaffold and maintain scaffold-balloon engagement relied on to hold the scaffold to the balloon when the scaffold is being delivered to a target in a body. The sheath is removed by a health professional either by removing the sheath directly or using a tube containing the catheter.
