摘要:
One embodiment is directed to a system for deploying a device to a distal location across a vessel, comprising an elongate introducer sheath tubing member comprising open-cell fibrous wall material defining a lumen therethrough, wherein in a collapsed configuration the sheath has a first cross-sectional outer diameter and a first lumen inner diameter, and in an expanded configuration, the sheath has a second cross-sectional outer diameter and a second lumen inner diameter and a substantially non-porous expandable layer coupled to a proximal portion of sheath and configured to prevent fluids present in the lumen from crossing the fibrous wall material.
