Abstract: A suture rigging assembly for use with a prosthetic heart valve delivery device includes a coupling ring having a plurality of apertures, and at least one tether coupled to the apertures of the coupling ring and extending distally therefrom. Each tether is formed by two lengths of suture thread, the lengths of suture thread joined together at a position spaced from the coupling ring, and a second joining of the lengths of suture thread forming an attachment loop at the distal end of the tether. The first connection in the tethers collectively define the shortest and longest lengths of each of the tethers, and the attachment loops provide a mechanism to releasably attach the tethers to a prosthetic heart valve. Optionally, knots can be used to join the tethers and one or more tethers may include a radiopaque marker secured thereon between two knots.
