An exemplary surgical apparatus may include a guide catheter including a clip channel, at least one hook channel, and at least one sling channel defined therein; a clip applier movable within the clip channel, wherein the clip applier holds at least one clip; at least one hook movable within a corresponding hook channel; and at least one sling movable within a corresponding sling channel. An exemplary surgical method for treating a mitral valve may include providing a guide catheter; a clip applier held by the guide catheter, and a clip held by the clip applier; introducing the distal end of the guide catheter into the left atrium; engaging the anterior and posterior leaflets of the mitral valve with the clip; closing the clip; and disengaging the clip applier from the clip, whereby the clip remains in the mitral valve. Another exemplary surgical method for treating a valve may include providing a guide catheter; a clip applier held by the guide catheter, and at least one clip held by the clip applier; advancing the guide catheter into proximity to the valve; and applying at least one clip substantially in the middle of the valve to create two orifices, one on each side of the clip. |
