Implantable tissue scaffold

A biodegradable scaffold for wound closure including a central rod and two spaced-apart plates. The central rod may have an engagement block on top for stabilizing an implanting tool. The two spaced-apart plates include an upper plate connected to the central rod and a lower plate connected to the central rod. Each of the upper and lower plates may include perforations which may be useful for detachably connecting an implanting tool and which encourage ingrowth of the tissue. The biodegradable scaffold allows tension free anatomic alignment of tissue within the plates and facilitates wound healing. The upper and lower plate may have a helical portion, in which each plate may extend around the central rod. The helical portion serves to draw or pull tissue around the wound defect into the scaffold in the course of deploying the scaffold.
