Patent ID: 8308758

Claim:
A closure device assembly for sealing an incision channel extending from a tissue surface of a patient, through a wall of a vessel and into the vessel, in conjunction with an introducer whose proximal end is outside the tissue surface, said closure device assembly comprising: the introducer, the introducer having an open distal end, a cylindrical outer surface, and a cylindrical inner surface defining a lumen configured for passing a medical instrument therethrough and through the open distal end of the introducer; and a closure device including: a body comprising a non-fluid haemostatic material; and at least one attachment mechanism, connected to the body, the attachment mechanism including: a side opening dimensioned and configured such that the attachment mechanism is connectable to the introducer by approaching the introducer from a side, while longitudinal axes of the introducer and closure device are substantially parallel to each other, and applying force in at least a transverse direction to thereby snap the attachment mechanism on to a side of the introducer such that the body is off-set to a side of the introducer, and a sliding surface configured such that the closure device is slidable along the cylindrical outer surface of the introducer, wherein the assembly is configured such that, when the closure device is initially attached to the introducer, both the haemostatic material and the attachment mechanism are located within at least a distal end portion of the body of the closure device.
