DETACHABLE SEALING PLUG WITH SAFETY RELEASE MECHANISM AND METHODS

摘要

A vascular closure system includes a carrier tube, an expandable anchor, a bioadhesive material, a sealing tip, and a filament. The expandable anchor is mounted to the carrier tube and configured to extend through a vessel puncture to temporarily seal the vessel puncture from within a vessel. The bioadhesive material is disposed outside of the vessel and configured to seal the vessel puncture. The sealing tip is mounted to the carrier tube distal of the expandable anchor. The filament is connected to and extends proximally from the sealing tip. Applying tension in the filament maintains connection of the sealing tip to the carrier tube, and releasing the tension in the filament permits release of the sealing tip within a channel formed in the bioadhesive material upon removal of the anchor through the bioadhesive material to seal the channel.
