A medical device for installing sutures to close an incision in tissue or human skin is disclosed. The suturing device may provide first and second arcuate needles. Once properly positioned, the first and second arcuate needles are driven through the sub-dermal layer, or alternatively through a superficial surface, of two sections of skin to be joined. This is done in arcuate fashion and at identical and symmetrical rates of angular displacement. During the driving or retraction process of the first and second arcuate needles, a suture is positioned within both the first and second sections of skin and transformed from a planar or a multi-planar serpentine orientation to a helical orientation. The resulting suturing process is thus much faster than conventional or manual suturing and results in superior wound approximation / alignment that will lead to decreased scarring compared to prior art devices.
