Patent ID: 7361183

Claim:
A device for sealing a puncture in the wall of a body lumen comprising an elongate member having a lumen therein and a distal port in a distal region thereof and a proximal port in a proximal region thereof, each of said ports communicating with said lumen in said elongate member, an obturator housed in said elongate member, a distal portion of said obturator having a relatively large external dimension which is coupled to a shaft which extends proximally from the distal portion thereof, said obturator being provided with a central lumen which extends from the distal end of said obturator proximally through said shaft, a groove in the external surface of the distal portion of the obturator, and a guidewire extending through said lumen in said elongate member and through said groove, said guidewire having a distal region capable of resisting proximal movement, but being sufficiently flexible to be withdrawn proximally through said groove.
