Abstract
A closure assembly includes an insertion sheath insertable into a tissue puncture and a tissue puncture closure device insertable through the insertion sheath and into the tissue puncture. The tissue puncture closure device includes a dual lumen delivery tube, a first sealing sleeve, and a second sealing sleeve. The dual lumen delivery tube has a first lumen configured to deliver a volume of sealing material to the tissue puncture, and a second lumen sized for insertion of a balloon location device. The first sealing sleeve is positioned between an outer surface of the dual lumen delivery tube and an inner surface of the insertion sheath to limit backflow of the sealing material into the insertion sheath. The second sealing sleeve is positioned between an outer surface of the balloon location device and an inner surface of the second lumen to limit backflow of the sealing material into the second lumen.
