Patent ID: 6994689

Claim:
A device for occluding a vascular segment, comprising: a tubular member having a proximal end portion and a distal end portion and a lumen extending therethrough; an expandable member at the distal end portion of the tubular member, the expandable member being formed at least in part from a braided structure; an elongate member having a proximal end portion and a distal end portion, wherein the distal end portion is connected to the expandable member, and the elongate member extends longitudinally within the lumen of the tubular member, the elongate member being longitudinally moveable between a first position wherein the expandable member is in a collapsed configuration, and a second position wherein the expandable member is in an expanded configuration, and wherein the elongate member moves proximally longitudinally with respect to the tubular member as the expandable member moves from its collapsed configuration to its expanded configuration; and an occluding membrane encapsulating the expandable member, the occluding membrane being configured to completely occlude blood flow in the vascular segment.
