Patent ID: 7621936

Claim:
A method of facilitating hemostasis of a blood vessel puncture, the method comprising: inserting a tubular device into a puncture in a blood vessel to establish access to the blood vessel; providing a vessel closure system around the tubular device; providing a proximal stop having a distal end adapted to be disposed within a space between the vessel closure system and the tubular device, the proximal stop defining a single chamber aperture sized to receive the tubular device; introducing a hemostasis promoting material into the space between the tubular device and vessel closure system, the hemostasis promoting material being situated distal to a distal end of the proximal stop; withdrawing the tubular device completely from the vessel closure system; inserting a pusher into the vessel closure system after the tubular device is withdrawn, the pusher being separate from the proximal stop and including a distal end sized for insertion into the single chamber aperture of the proximal stop; and effecting proximal movement of the vessel closure system with respect to the pusher to deliver the hemostasis material adjacent to the puncture and facilitate hemostasis of the puncture.
