DEVICE AND METHOD OF TREATING HEART VALVE MALFUNCTION
First Claim
1. An instrument assembly for treating heart valve malfunction, said instrument assembly comprising:
- at least one elongated chord and an introductory sheath, said sheath at least initially disposed in enclosing relation to said one chord and movable with said chord and along the length thereof,said sheath and said one chord cooperatively structured to concurrently enter the heart chamber through the heart wall and penetrate and pass through a predetermined heart valve leaflet,an anchor connected to a distal end of said one chord and disposable into an anchored relation with the heart wall substantially oppositely disposed to the predetermined valve leaflet,a securing assembly connectable to a proximal extremity of said one chord in an interconnecting position between said one chord and the predetermined valve leaflet, andsaid anchored relation of said anchor and said interconnecting position of said securing assembly collectively defining an operative length of one said chord within the heart chamber and a tensioning of the predetermined valve leaflet sufficient to restrict prolapsing of the predetermined valve leaflet, by said one chord.

Abstract
An assembly and method for treating heart valve malfunction typically including treating of mitral regurgitation wherein an instrument assembly includes an elongated chord movably disposed within an introductory sheath and including an anchor secured to a distal end thereof. An attendant method includes concurrently introducing the sheath and the chord into the heart chamber through an exterior wall and penetrating and passing the sheath and the chord through the anterior mitral valve leaflet. The sheath and the chord are then extended transversely across the heart chamber and the distal end of the chord is anchored to an opposing portion of the heart wall. The sheath is then withdrawn back along the length of the anchored chord and through the anterior mitral valve leaflet and a securing member connects the proximal end of the chord to the valve leaflet. The chord is secured between the valve leaflet and the opposing heart wall under sufficient tension to maintain an intended positioning of the valve leaflet to overcome mitral regurgitation.

18. A method of treating heart valve malfunction comprising:
-
passing an instrument into the heart chamber and into penetrating relation to a predetermined valve leaflet under the siege of prolapse, passing the instrument through the predetermined valve leaflet, extending at least one chord of the instrument from the predetermined valve leaflet across the heart chamber into anchored relation with a portion of the heart wall substantially opposing the predetermined valve leaflet, withdrawing a sheath of the instrument back along a length of the anchored one chord from the opposing portion of the heart wall and back through the predetermined valve leaflet, and securing a corresponding proximal extremity of the one chord to the predetermined valve leaflet. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
