Wound closure apparatus and method
First Claim
1. A method for suturing a wound in a body wall having a near side and a far side, comprising the steps of:
- providing a wound closure apparatus including a proximal section, a distal section and an intermediate section;
providing a suture having two ends and a suture loop therebetween;
providing an expansion mechanism in the distal section of the apparatus, the expansion mechanism being operable to move the suture between a first position and a second position disposed radially outwardly of the first position,providing a finger tab in the proximal section of the apparatus;
inserting the distal section through the wound from the near side to the far side of the body wall;
deploying a pair of needles through the body wall surrounding the wound to form an associated pair of needle holes;
moving the finger tab in the proximal section of the apparatus to operate the expansion member and move the suture between the first and second positions to thread the needles on the far side of the body wall;
withdrawing the threaded needles through the needle holes to access the ends of the suture on the near side of the body wall; and
withdrawing the distal section of the apparatus through the wound.

Abstract
Apparatus for suturing a wound in a body cannula having an axis extending between a proximal end and a distal end. A handle is disposed at the proximal end and a pair of needles disposed at the distal end, the needles being movable between a proximal position and a distal position. A suture manipulator carried by the cannula is insertable through the wound and operable to manipulate the suture into an engaging relationship with the needles on the far side of the body wall. A finger tab is movable on the handle in a single distal direction through multiple stage. In a first stage the needles are deployed; in a second stage, the suture manipulator is activated to thread the needles; and in a third stage the suture is released from a tensioning mechanism. In an associated method the needles are threaded on the far side of the body wall and withdrawn from the wound providing access to the suture ends on the near side of the body wall. Tying the suture ends closes the wound.

3. A wound closure apparatus for suturing a wound in a body wall, comprising:
-
a cannula having an axis extending between a proximal end and a distal end; a handle disposed at the proximal end of the cannula; a catheter coupled to the distal end of the cannula, the catheter being sized and configured to extend through the wound in the body wall; a suture extending at least partially through the cannula and the catheter; a suture manipulator associated with the catheter and operable to manipulate the suture relative to the cat meter; a pair of needles extendable from the cannula into proximity with the catheter; and a finger tab movable relative to the handle to operate the suture manipulator in order to move the suture into threading engagement with the needles. - View Dependent Claims (4, 5, 6, 7)

8. A wound closure apparatus for a wound in a body wall, comprising:
-
a cannula having an axis extending between a proximal end and a distal end; a handle disposed at the proximal end of the cannula; a catheter coupled to the distal end of the cannula, the catheter being sized and configured to extend through the wound in the body wall; a pair of needles movable from a proximal position in proximity to the cannula to a distal position in proximity to the catheter; a suture having a first end and a second end, a suture manipulator associated with the catheter for moving the suture relative to the needles; an actuator movable in a first direction relative to the handle to move the needles from the proximal position to the distal position; and the actuator having properties for being moved in the direction to operate the suture manipulator and move the suture into threading with the needles. - View Dependent Claims (9, 10, 11, 12)
