Seamless expandable introducer sheath

An introducer sheath assembly (10) includes an expandable introducer sheath (12) including an expandable braided portion (16) defining an elongate tubular member movable between a contracted configuration for delivery and an expanded configuration for deployment, the expandable braided portion having a first length when in the contracted configuration, and the expanded braided portion having a second length when in the expanded configuration. And has a reduced second length when in the expanded configuration. The introducer sheath assembly includes a dilator (14) adapted to releasably hold the expandable introducer sheath in its contracted configuration for delivery until the dilator is actuated to release the expandable knit from the dilator, thereby allowing the expandable knit to expand to its expanded configuration. 一种导引器鞘套组件(10)，其包括可扩张的导引器鞘套(12)，该可扩张的导引器鞘套包括限定细长管状构件的可在用于递送的收缩构造和用于展开的扩张构造之间移动的可扩张的编织部(16)，可扩张的编织部在处于收缩构造时具有第一长度，并且在处于扩张构造时具有缩小的第二长度。导引器鞘套组件包括扩张器(14)，该扩张器适于将可扩张的导引器鞘套可释放地保持在其收缩构造以用于递送，直到扩张器被致动以
