An embodiment includes an artificial chordae tendineae system comprising: a first needle; a flexible first chord coupled to a proximal end portion of the first needle; a first proximal pledget coupled to a proximal end portion of the first chord; a first distal conduit coupled to the first chord between the first proximal pledget and the first needle; wherein: the first distal conduit includes first and second faces; one of the first and second faces includes a first aperture; a sidewall of the first conduit, located between the first and second faces, includes a sidewall aperture that does not directly connect to the first aperture; the sidewall aperture is configured to include a portion of the first chord when the first distal conduit is permanently implanted adjacent tissue but not when the first distal conduit is traversing the tissue before being permanently implanted adjacent the tissue.

Pull-through chordae tendineae system

An embodiment of the invention includes a sewing cuff for aortic heart valves that better approximates native anatomy by better mating with the crown-like anatomical annulus. Limiting distortion of the crown-like annulus provides better blood flow and overall valve function and provides a physician greater ease of implantation since native anatomy is not flattened. Thus, the surgeon may attach sutures to the fibrous tissue of the crown-like anatomical annulus without distorting the shape of the native anatomy. An embodiment includes a scalloped sewing cuff assembly (with semilunar arches) that tracks the crown-like annulus. Another embodiment provides a sewing cuff positioned over the majority of the valve's length, thus allowing the surgeon greater flexibility as to where he or she can attach sutures to the surgical annulus. Conventional valves, which are primarily 'low-profile' devices, do not offer such ability. Other embodiments are described herein.
