摘要：
Assemblies and methods for occluding a vascular vessel are disclosed. An assembly can include a removable outer member, an elongate expandable member, a porous cover member, and optionally, one or both of a removable inner tubular member or a seal member. The elongate expandable member and the porous cover member can be positioned in a radially compressed form between the removable outer members and, if present, the inner tubular member, with the porous cover member surrounding an outer surface of the elongate expandable member. The elongate expandable member can be configured to expand the porous cover member and occlude a vascular vessel following removal of the removable outer member. Mechanical stability and migration resistance of the elongate expandable member can be aided by the porous cover member. The seal member can be positioned at a distal end of the elongate expandable member to inhibit its expansion during vessel insertion.
