Tissue opening locator and everter and method
First Claim
1. A device for precisely locating a wound in a blood vessel, comprising:
- an elongate tube having a proximal end, a distal end, and an elongate lumen, the tube being configured to slidably accommodate a guidewire therewithin; and
at least two indicator holes through an outer wall of the tube and communicating with the lumen, a distance between the distal end and each of the indicator holes being substantially the same.

Abstract
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.

12. A device for locating a vascular wound, comprising:
-
a retractor comprising two elongate members adapted to move relative to each other between open and closed positions, each member having a distal end and a proximal end, and the members are adapted to define a longitudinal channel therebetween when in the closed position; and
a catheter comprising;
a lumen connected to a source of negative pressure;
an opening formed through an outer wall of the catheter and communicating with the lumen; and
a guide point defined on an outer surface of the catheter proximal of the opening, a longitudinal distance between the opening and the guide point being at least the same as the thickness of a vascular vessel wall;
wherein the distal ends of the retractor members are positioned at or adjacent the guide point. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
