Abstract

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.

Claims

1. A surgical apparatus, comprising:

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 said clip channel, wherein said clip applier holds at least one clip;

at least one hook movable within a corresponding said hook channel; and

at least one sling movable within a corresponding said sling channel.

2. The surgical apparatus of claim 1, wherein said hook channels and said sling channels are alternately positioned and substantially evenly spaced about the perimeter of said guide catheter.

3. The surgical apparatus of claim 1, wherein each said hook channel and each said sling channel is positioned radially outward from said clip channel.

4. The surgical apparatus of claim 1, wherein said guide catheter is a tube with a lumen defined therein;

wherein at least one of said hook channels and said sling channels is a discrete tube positioned within said lumen of said guide catheter.

5. The surgical apparatus of claim 1, wherein at least one sling includes a generally D-shaped broad section.

6. The surgical apparatus of claim 1, wherein said clip has at least three tines.

7. The surgical apparatus of claim 1, wherein said clip is splayable.
