An apparatus for facilitating the locating, everting, and closing of an opening
in a blood vessel. The apparatus can include a closure instrument having an elongated
member defining a longitudinal axis and proximal and distal ends. The elongated
member has a vacuum lumen extending at least a portion of the length thereof for
conveying a vacuum and terminating in a vacuum port adjacent the distal end of
the elongated member. The distal end of the elongated member is dimensioned to
be positioned proximal a vessel opening in a blood vessel whereby vessel edge portions
defining the vessel opening are at least partially drawn toward the vacuum port
in response to a vacuum conveyed through the vacuum lumen. At least one surgical
clip is mounted adjacent the distal end of the elongated member and is adapted
to be formed to an at least partially formed condition thereof. The one clip is
positioned with respect to the vacuum port so as to engage the vessel edge portions
drawn toward the vacuum port when the clip is moved to the formed condition, thus
at least partially closing the vessel opening. A method for locating, everting,
and closing an opening in a blood vessel is also disclosed.
