Patent 10512455 was granted and assigned to Access Closure on December, 2019 by the United States Patent and Trademark Office.
Apparatus and methods for sealing a puncture through tissue includes an introducer sheath sized for introduction into a puncture, cartridge sized for insertion into the introducer carrying a sealant, and a locking element for coupling the introducer sheath to the cartridge. When the cartridge is advanced into the introducer sheath, the locking element couples the introducer sheath to the cartridge such that subsequent retraction of the cartridge causes the introducer sheath to retract, thereby deploying the sealant from the cartridge within the puncture beyond the introducer sheath.
