Abstract
A vessel puncture closure device includes a balloon catheter and a sealant delivery device. The balloon catheter has an inflatable balloon positioned at a distal end thereof. The sealant delivery catheter has a sealant lumen configured to delivery a volume of sealant to a vessel puncture. The sealant delivery catheter is configured to move axially relative to the balloon between a first position in which the sealant delivery catheter delivers a first volume of sealant to the vessel puncture, and a second position spaced proximal of the first position to deliver a second volume of sealant to the vessel puncture.
