Abstract
The present invention provides devices for safely closing an opening in tissue using suture. In one embodiment, the device includes an elongated main body constructed to permit visualization longitudinally through the main body from the proximal end to the distal end, the distal end defining a support surface to support the suture and protect distal body structures. A flange is connect to the main body adjacent the proximal end and projects laterally therefrom in first and second lateral directions. First and second guide holes extend longitudinally through the flange, and are structured to direct a suturing instrument longitudinally towards the support surface for passing the suture.
