摘要：
An insertion sheath and related methods include a tube member and a shape memory feature. The tube member defines an insertion lumen. The shape memory feature is positioned at a distal end portion of the tube member. The shape memory feature provides a monofold shape in the tube member when in a first state, and a radially expanded shape in the tube member in a second state upon application of an expansion force. The shape memory feature returns the monofold shape after removal of the expansion force. The insertion sheath may function as an access to closure sheath that is suitable for use as a procedural insertion sheath when treating the patient and a closure insertion sheath when sealing closed the vascular puncture.
摘要（中）：
插入鞘和相关方法包括管构件和形状记忆特征。 管构件限定插入腔。 形状记忆特征位于管构件的远端部分。 当处于第一状态时，形状记忆特征在管构件中提供单倍形状，并且在施加膨胀力时在第二状态下在管构件中形成径向扩张形状。 形状记忆特征在去除膨胀力之后返回单峰形状。 插入护套可用作接近闭合护套，当封闭血管穿刺时，当治疗患者时，适合用作手术插入鞘，以及封闭插入鞘。
