APPARATUS AND METHODS FOR SEALING A VASCULAR PUNCTURE
First Claim
1. An apparatus for sealing a puncture extending through tissue having an introducer sheath therein, comprising:
- a cartridge comprising a proximal end, a distal end sized for insertion through an introducer sheath within a puncture through tissue, a lumen extending between the proximal and distal ends;
a locking element on the cartridge comprising an extension sized for introduction into the proximal end of the introducer sheath when the cartridge is inserted into the introducer sheath;
a sealant disposed within the lumen of the cartridge; and
a pusher member disposed within the cartridge lumen for deploying the sealant distally from the cartridge lumen when the cartridge is retracted proximally relative to the pusher member.

Abstract
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.

4. A system for sealing a puncture extending through tissue, comprising:
-
an introducer sheath comprising a proximal end, a distal end sized for insertion through a puncture through tissue, and a lumen extending between the proximal and distal ends; a tubular member comprising a proximal end, a distal end sized for insertion into the introducer sheath lumen, a lumen extending between the tubular member proximal and distal ends; a sealant disposed within the tubular member lumen; and a locking element carried on the tubular member for coupling the introducer sheath to the tubular member when the tubular member is advanced into the introducer sheath lumen such that subsequent proximal movement of the tubular member causes corresponding proximal movement of the introducer sheath such that sealant is deployed beyond the introducer sheath distal end. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

12. An apparatus for sealing a puncture extending through tissue having an introducer sheath therein, comprising:
-
a cartridge comprising a proximal end, a distal end sized for insertion through an introducer sheath within a puncture through tissue, a lumen extending between the proximal and distal ends; a locking element carried on the cartridge sized for introduction into a proximal end of an introducer sheath and comprising one or more features for engaging the proximal end of the introducer sheath when the cartridge is inserted into the introducer sheath to thereby couple subsequent proximal movement of the introduced sheath to proximal movement of the cartridge; a sealant disposed within the lumen of the cartridge; and a pusher member disposed within the tubular member lumen for deploying the sealant distally from the tubular member lumen when the tubular member is retracted proximally relative to the pusher member. - View Dependent Claims (13, 14)

15. A method for sealing a puncture extending through tissue to a body lumen, comprising:
-
introducing an introducer sheath into the puncture; advancing a tubular member carrying a sealant therein into the introducer sheath until a locking element on the tubular member is received within and engages a proximal end of the introducer sheath to couple the introducer sheath to the tubular member; and retracting the tubular member at least partially from the puncture, thereby retracting the introducer sheath with the tubular member at least partially from the puncture and exposing the sealant within the puncture distally beyond the introducer sheath. - View Dependent Claims (16, 17, 18, 19)
