Claim 16:
17. A system for sealing a puncture extending through tissue, comprising:
an introducer sheath comprising a proximal end, a distal end sized for insertion through the puncture extending through tissue, and a lumen extending between the proximal end and the distal end of the introducer sheath;
a positioning member comprising a proximal end, a distal end sized for insertion into the lumen of the introducer sheath, and a lumen extending between the proximal end of the positioning member and the distal end of the positioning member;
a sealant disposed within the positioning member lumen; and
a locking element carried on the positioning member for coupling the introducer sheath to the positioning member when the positioning member and the locking element are advanced into the lumen of the introducer sheath such that subsequent proximal movement of the positioning member causes a corresponding proximal movement of the introducer sheath such that the sealant is deployed beyond the distal end of the introducer sheath wherein the locking element comprises a sleeve and an extension extending distally therefrom, the extension having at least one locking feature extending radially outwardly therefrom, the extension and the at least one locking feature being in a contracted position when the positioning member is inserted into the sleeve but not the extension, and wherein the at least one locking feature is selected from the group comprising a flange, a catch, and a detent.
