Abstract
Artificial chordae having a strand member and a first and second pair of sutures at either longitudinal end of the strand member. The artificial chordae is preferably a unitary unit, formed from inelastic flexible material. In one embodiment, the artificial chordae comprises multiple strand members joined together at a joined end. Different sized artificial chordae are provided sized to fit the patient'"'"'s heart. The appropriately sized artificial chordae is chosen by using a chordae sizing gauge having a shaft and a transverse member, to measure the space within the patient'"'"'s heart where the artificial chordae is attached. The artificial chordae

22. A method of attaching an artificial chordae in a heart, comprising:
-
a) providing an artificial chordae, comprising;
at least one strand member having a first end and a second end, and configured to extend from a papillary muscle to a location on the heart valve; and
a first pair of sutures extending from the first end of the strand member and a second pair of sutures extending from the second end of the strand member; and
b) attaching the sutures to the papillary muscle and to the heart valve, to attach the artificial chordae in the heart. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)

32. An artificial chordae for a heart valve of a patient'"'"'s heart, comprising:
-
a) a suture having a first end and a second end; and
b) a first stopping member on the first end, and a second stopping member on the second end, each securing member being configured to secure to the suture, to thereby secure the suture within the patient'"'"'s heart. - View Dependent Claims (33, 34)

35. A method of attaching an artificial chordae in a patient'"'"'s heart, comprising:
-
a) providing an artificial chordae comprising a suture having a first end and a second end; and
a first stopping member on the first end and a second stopping member on the second end, each stopping member being configured to secure to the suture for securing the suture within the patient'"'"'s heart;
b) attaching the first end of the suture to a papillary muscle of the patient'"'"'s heart by stitching the first end of the suture through the papillary muscle from a first side of the muscle to a second side of the muscle, and positioning the stopping member at a location on the suture adjacent the second side of the papillary muscle, and securing the stopping member to the suture to thereby prevent the displacement of the suture from the second side to the first side of the papillary muscle; and
d) attaching the second end of the suture to a valve leaflet edge of the patient'"'"'s heart by stitching the second end of the suture through the valve leaflet edge at a location on the valve leaflet edge from a first side of the valve leaflet edge to a second side of the valve leaflet edge so that a length of suture conforms to a length between the papillary muscle and the location on the valve leaflet edge, and positioning the stopping member at a location on the suture adjacent the second side of the valve leaflet edge, and securing the stopping member to the suture to thereby prevent the displacement of the suture from the second side to the first side of the valve leaflet edge.
