A port site closure instrument comprising: a body defining a central longitudinal axis ("A"), a first plane ("B"), and a second plane ("C") perpendicular to the first plane, the first and second planes intersecting along the central longitudinal axis, the body having: a proximal portion defining a first proximal suture aperture, a first needle aperture, and a second needle aperture, the first and second needle apertures offset from the central longitudinal axis; a central portion defining a third needle aperture and a fourth needle aperture, a first needle channel defined through the body communicating the third needle aperture with the first needle aperture, a second needle channel defined through the body communicating the fourth needle aperture with the second needle aperture, the first and second needle channels positioned in the first plane; and a distal portion; and a pair of wings pivotally supported by the distal portion of the body, the pair of wings being pivotable between an open position and a closed position, wherein the body defines distal suture apertures in the first plane ("B") on opposite sides of the central portion, the distal suture apertures being located distally of the third and fourth needle apertures and proximally of the pair of wings, a first suture channel defined by the body communicating the distal suture apertures with the first proximal suture aperture; and an outer surface of each of the wings defining a suture slot positioned along the first plane ("B") such that a suture exiting a respective one of the distal suture apertures and positioned in the suture slots is aligned with a respective one of the first or second needle channels. a body defining a central longitudinal axis ("A"), a first plane ("B"), and a second plane ("C") perpendicular to the first plane, the first and second planes intersecting along the central longitudinal axis, the body having: a proximal portion defining a first proximal suture aperture, a first needle aperture, and a second needle aperture, the first and second needle apertures offset from the central longitudinal axis; a central portion defining a third needle aperture and a fourth needle aperture, a first needle channel defined through the body communicating the third needle aperture with the first needle aperture, a second needle channel defined through the body communicating the fourth needle aperture with the second needle aperture, the first and second needle channels positioned in the first plane; and a distal portion; and a proximal portion defining a first proximal suture aperture, a first needle aperture, and a second needle aperture, the first and second needle apertures offset from the central longitudinal axis; a central portion defining a third needle aperture and a fourth needle aperture, a first needle channel defined through the body communicating the third needle aperture with the first needle aperture, a second needle channel defined through the body communicating the fourth needle aperture with the second needle aperture, the first and second needle channels positioned in the first plane; and a distal portion; and a pair of wings pivotally supported by the distal portion of the body, the pair of wings being pivotable between an open position and a closed position, wherein the body defines distal suture apertures in the first plane ("B") on opposite sides of the central portion, the distal suture apertures being located distally of the third and fourth needle apertures and proximally of the pair of wings, a first suture channel defined by the body communicating the distal suture apertures with the first proximal suture aperture; and an outer surface of each of the wings defining a suture slot positioned along the first plane ("B") such that a suture exiting a respective one of the distal suture apertures and positioned in the suture slots is aligned with a respective one of the first or second needle channels.
