Methods, devices, and kits for treating mitral valve prolapse
View Patent ↗Described here are methods, devices, and kits for treating a prolapsed valve leaflet. The devices generally comprise a flexible cord, a first anchor attached to the cord at its distal end, and a second anchor slidably attached to the cord. The first anchor may be configured to secure the cord to cardiac tissue located below a prolapsed valve leaflet and the second anchor may be configured to secure into the prolapsed valve leaflet. Also described are methods for treating a prolapsed valve including the steps of securing a first anchor to cardiac tissue located below the prolapsed mitral valve leaflet, securing a second anchor to the prolapsed mitral valve leaflet, tensioning a cord connecting the two anchors and securing the cord. Kits including the described devices are also provided.
1. A method for treating a prolapsed mitral valve leaflet comprising:
advancing a flexible cord, having a first anchor attached at its distal end to the proximity of the prolapsed mitral valve leaflet;
securing the first anchor to cardiac tissue located below the prolapsed mitral valve leaflet;
securing a second anchor slidably attached to the cord into the prolapsed mitral valve leaflet;
tensioning the cord after the second anchor has been secured into the prolapsed mitral valve leaflet; and
cutting the cord comprising advancing a looped cutting wire over the cord; positioning the looped cutting wire proximal of the second anchor; and pulling on the cutting wire to cut the cord.
2. The method of claim 1 further comprising fixing the cord in its tensioned position.
3. The method of claim 2 wherein fixing the cord further comprises applying a fastener to the cord.
4. The method of claim 1 wherein the cardiac tissue is selected from the group consisting of a papillary muscle and a ventricular wall.
