Abstract:
1. A vasculature closure device, comprising: an expandable support frame deployable within a vessel; a sealing membrane at least partially supported by the expandable support frame; a cross-member support extending across at least a portion of the sealing membrane and attached to opposing sides of the support frame; and an anchoring tab or a pull string fixedly attached to at least one of the support frame, the sealing membrane, and the cross-member support; wherein, upon deploying the support frame within the vessel, the device is positioned entirely within the vessel except for the anchoring tab or the pull string; and wherein, upon expanding the support frame within the vessel, the device is configured to intraluminally push the sealing membrane against a puncture site existing in a vessel wall, such that the sealing membrane prevents fluid blood leakage through the puncture site.
