Abstract
An apparatus for sealing a passage through tissue includes a bioabsorbable, threaded plug carried by a delivery device. A guide wire is receivable through lumens in the plug and delivery device that includes wings on a bioabsorbable distal portion. With the wings collapsed, the guide wire is advanced through the passage into a blood vessel, the wings expanding once located within the vessel, and the guide wire is withdrawn until the wings contact the vessel wall. The plug is threaded into the passage over the guide wire until the plug is disposed adjacent the wings. The distal portion of the guide wire is secured to the plug, e.g., by compressing a collet within the plug lumen that seals the lumen, and is severed from a proximal portion thereof. Thus, the plug and distal portion are deployed with the plug sealing the passage.
