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 In an associated method the needles are threaded on the far side of the body wall and withdrawn from the wound providing access to the suture ends on the near side of the body wall.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.

[ We 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;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;inserting a suture having two ends and a suture loop extending therebetween directly into and through the wound from the near side to the far side of the body wall;manipulating the suture into threading engagement with the needles;withdrawing the threaded needles through the needle holes to access the ends of the suture on the near side of the body wall; andwithdrawing the distal section of the apparatus through the wound.
