Patent ID: 8491628

Claim:
An assembly for closing a vascular wound comprising: a hemostatic material; a delivery tube having a proximal end and a distal end, an inner wall of the delivery tube defining a chamber that accommodates the hemostatic material therewithin, the chamber tapering along its length so that at a first point along its length the chamber has a first diameter, at a second point spaced proximally from the first point the chamber has a second diameter, and at a third point spaced proximally from the second point the chamber has a third diameter, the first diameter being less than the second diameter, the second diameter being less than the third diameter; a catheter extending through the delivery tube, the chamber being defined between the catheter and the inner wall, the distal end of the delivery tube engaging the catheter; an apparatus configured to position the distal end of the delivery tube at or near a vascular wound; a pusher member having an engagement portion configured to fit within the chamber, the engagement portion of the pusher member having an engagement portion diameter approximating the second diameter; and the hemostatic material being within the chamber between the first point and the third point, the chamber enclosing the hemostatic material therewithin, the engagement portion of the pusher member being proximal of the hemostatic material; wherein the pusher member and chamber are configured so that when the pusher member is moved distally relative to the delivery tube, the hemostatic material remains enclosed within the chamber and generally distal of the pusher member engagement portion until the pusher member engagement portion engages the inner wall and deforms the delivery tube so that at least one opening is created in the chamber, and the pusher member dispatches the hemostatic material through the at least one opening created when the pusher member deforms the delivery tube.
