Method and system for sealing percutaneous punctures

摘要

A puncture closure device operable to seal closed a vessel puncture in a vessel. The puncture closure device includes a delivery member insertable through a tissue tract to the vessel puncture, a sealing material, and an expandable member. The sealing material is deliverable through the delivery member to the vessel puncture and configured to seal closed the vessel puncture from outside the vessel. The expandable member is positionable within the vessel through a vessel access distinct from the vessel puncture and is operable to temporarily seal closed the vessel puncture from within the vessel to restrict passage of the sealing material into the vessel.
