1. A method of manufacturing a balloon cuff comprising:
loading a tube into a mold assembly, wherein the mold assembly comprises a tapered shape;
stretching the tube loaded into the mold assembly;
applying pressure to the stretched tube loaded into the mold assembly to achieve positive pressure within the tube;
relaxing stretching of the tube loaded into the mold assembly while increasing the positive pressure within the tube; and
removing the tube from the mold assembly subsequent to increasing the positive pressure within the tube, wherein the tube, when removed, comprises a balloon cuff that comprises a tapered section that, when inflated, conforms to the tapered shape, wherein at least a portion of the tapered section is configured to form a wrinkle-free sealing band at least 1 millimeter in length against a patient's tracheal wall only when the balloon cuff is inflated and wherein at least a portion of the tapered section is configured to form a wrinkled band against the patient's tracheal wall, wherein the wrinkled band is longer than the wrinkle-free sealing band when the balloon cuff is inflated within the trachea.
