In accordance with the present invention there is provided a suturing device. The suturing device includes a length of suture that will be delivered to the site of the PFO and placed through the tissue adjacent the opening to close the PFO. As described in greater detail below, the suture is advanced through the tissue surrounding the opening by a pair of needles that penetrate the tissue adjacent to the opening. A knot is then loosely tied with the length of suture and advanced to the site of the PFO. The tails of the suture extending from the knot are then cut and removed. It is also contemplated that a pre-formed or pre-tied knot may be disposed on the device, wherein after deployment of the suture through the tissue adjacent to the PFO and removal of the device a loop of suture having a pre-tied knot will remain, wherein the pre-tied knot may then be tightened to close the PFO. Further still it is contemplated that other means may be utilized to retain the sutures. For example, it is contemplated that a suture clip or other clip like device may be utilized to retain the suture in a position such that the PFO is closed.
