A valve repair device and method of repair for the mitral valve of the heart is disclosed. The valve repair device includes a leaflet portion, a muscle portion, and a plurality of chords connecting the leaflet portion to the muscle portion. The valve repair device is attached to the diseased valve by suturing the leaflet portion to the affected leaflet and suturing the muscle portion to the affected muscle. The leaflet portion and muscle portion are constructed of cloth made from expanded polytetraflouroethylene. The chords are sutures also constructed from expanded polytetraflouroethylene. The suture position for the muscle portion is determined by positioning the valve repair device adjacent to a normal marginal chord. The valve repair device may be employed to repair the anterior leaflet or posterior leaflet of the mitral valve.

The device of claim 1, wherein said first portion comprises a cloth made of expanded polytetraflouroethylene. 3. The device of claim 1, wherein said at least one chord is a plurality of chords, each of said chords having opposite ends, one of each said ends being attached to said first portion, the other of each said ends being attached to said second portion. 4. The device of claim 3, wherein said chords being attached at one of each said ends to said first portion adjacent said outer periphery. 5. The device of claim 4, wherein said outer periphery is rounded. 6. The device of claim 3, wherein said chords are sewn to said first portion and to said second portion. 7. The device of claim 3, wherein said second suture is affixed at a first end to said second portion. 8. The device of claim 1, wherein said at least one chord are made of expanded polytetraflouroethylene. 9. The device of claim 1, wherein said outer periphery of said first portion is rounded. 10. The device of claim 1, wherein said second portion comprises a cloth made of expanded polytetraflouroethylene. 11. A method for repairing a heart valve, comprising: providing a device for repairing a heart valve, said device having a first portion, said first portion comprising a flexible element, said flexible element having an outer periphery, said outer periphery having an attachment area, a second portion, said second portion comprising a flexible element, at least one chord, said chord having opposite ends, one of said ends being attached to maid first portion, the other of said cads being attached to said second portion; suturing said first portion at least partially along said outer periphery to the native leaflet of a valve at said attachment area, wherein said first portion at least partially covers an opening, wound or defect in said leaflet; and suturing said second portion to a papillary muscle. 12. The method of claim 11 further comprising removing part of said first portion prior to suturing said first portion to the leaflet. 13. The method of claim 11 further comprising removing part of said chord prior to suturing said first portion to the leaflet. 14. The method of claim 11, wherein said first portion comprises a cloth made of expanded polytetraflouroethylene. 15. The method of claim 11, wherein said at least one chord is a plurality of chords, each of said chords having opposite ends, one of each said ends being attached to said first portion, the other of each said ends being attached to said second portion. 16. The method of claim 11, wherein said at least one chord being attached at one of each said ends to said first portion adjacent said outer periphery. 17. The method of claim 11, wherein said at least one chord are sewn to said first portion and to said second portion. 18. The method of claim 11, wherein said second portion comprises a suture having a first end attached to said second portion and a second end having a needle attached thereto. 19. The method of claim 11, wherein said first portion includes a rounded edge, said edge being attached adjacent to the scalloped edge of the leaflet. 20.
