Abstract
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.
