1. A delivery apparatus comprising:
a stented prosthesis; and
a delivery device configured to carry the stented prosthesis comprising:
a connector comprising a first aperture;
a first tension member comprising a first end portion forming a first tension loop and a third tension loop, and a second end portion forming a second tension loop, wherein the first tension loop, the second tension loop and the third tension loop are each configured to encircle the stented prosthesis, and the first tension member further comprising an intermediate segment positioned between the first end portion and the second end portion, wherein the intermediate segment is slidably disposed within the first aperture of the connector,
wherein the stented prosthesis is maintained in a collapsed orientation on a distal end portion of a shaft assembly of the delivery device by a tension in the first tension loop encircling the stented prosthesis, a tension in the second tension loop encircling the stented prosthesis, and a tension in the third tension loop encircling the stented prosthesis, and wherein slidably disposing the intermediate segment within the first aperture of the connector balances a tension between the first tension loop, the second tension loop, and the third tension loop.
