Abstract
A vascular closure system includes a balloon location device, a bioadhesive delivery device, and a sealing tip. The balloon location device includes a balloon for temporarily sealing a vessel puncture internally and at least one lumen for delivering inflation fluid to the balloon. The bioadhesive delivery device includes at least one lumen for delivery of the balloon location device to the vessel puncture. One of the balloon location device and the bioadhesive delivery device includes a first lumen for delivery of a first volume of bioadhesive to the vessel puncture. The sealing tip is releasable within a channel formed in the first volume of bioadhesive upon withdrawal of the balloon. One of the balloon location device and the bioadhesive delivery device is configured for delivery of a second volume of bioadhesive to the vessel puncture after the sealing tip is released in the channel.
