Method of replacing a defective atrio-ventricular valve with a total atrio-ventricular valve bioprosthesis
First Claim
1. A method of replacing a defective atrio-ventricular valve in a heart of a patient with a replacement atrio-ventricular valve from, a donor heart, the replacement atrio-ventricular valve having an annulus, a plurality of chordae and papillary muscles attached thereto, and an elongated membrane extending from each papillary muscle, the method comprising:
- removing the defective valve from the patient'"'"'s heart;
inserting each elongated membrane of the replacement valve longitudinally through a papillary muscle of the patient'"'"'s heart so that the membrane extends through the heart wall of the patient'"'"'s heart;
securing the annulus of the replacement valve to the annulus of the patient'"'"'s heart; and
securing the elongated membranes of the replacement valve to the exterior of the heart wall of the patient.

Abstract
The method of replacing a defective atrio-ventricular valve in a patient'"'"'s heart with a tissue atrio-ventricular valve bioprosthesis is provided. The replacement atrio-ventricular valve from the donor heart includes an annulus, a plurality of chordae, and papillary muscles attached thereto. The surgical operation includes removal of the defective valve from the patient'"'"'s heart, and the insertion of each papillary muscle of the replacement valve longitudinally into a corresponding papillary muscle in the patient'"'"'s heart. The papillary muscles of the replacement valve are secured in position within the patient'"'"'s heart and the annulus of the replacement valve is secured to the annulus of the patient'"'"'s heart. An introducer is utilized for inserting the papillary muscles of the replacement valve into the papillary muscle of the patient'"'"'s heart, using the Seldinger technique.
