An inflatable balloon cuff comprising: a proximal opening and a distal opening in a wall of the balloon cuff ; a first tapered section along an imaginary axis connecting the proximal opening and the distal opening of the inflated balloon cuff; and a second tapered section along an imaginary axis connecting the proximal opening and the distal opening of the inflated balloon cuff, wherein the second tapered section is disposed distally on the cuff relative to the first tapered section , wherein the first tapered section and the second tapered section taper away from one another or taper towards one another, wherein the first tapered section and the second tapered section (41b. 46a) each comprise: a respective sealing portion comprising a fully inflated cuff diameter that is substantially equal to a tracheal diameter when the cuff is fully inflated such that at least one of the respective sealing portions is configured to form a wrinkle-free sealing band at least 1 millimeter in length against a patient's tracheal wall when fully inflated; and a respective wrinkled portion wherein a widest fully inflated diameter of the wrinkled portion of the first tapered section and a widest fully inflated diameter of the wrinkled portion of the second tapered section are greater than the tracheal diameter such that at least one of the respective wrinkled portions is configured to form a wrinkled band against a patient's tracheal wall when inflated. a proximal opening and a distal opening in a wall of the balloon cuff ; a first tapered section along an imaginary axis connecting the proximal opening and the distal opening of the inflated balloon cuff; and a second tapered section along an imaginary axis connecting the proximal opening and the distal opening of the inflated balloon cuff, wherein the second tapered section is disposed distally on the cuff relative to the first tapered section , wherein the first tapered section and the second tapered section taper away from one another or taper towards one another, wherein the first tapered section and the second tapered section (41b. 46a) each comprise: a respective sealing portion comprising a fully inflated cuff diameter that is substantially equal to a tracheal diameter when the cuff is fully inflated such that at least one of the respective sealing portions is configured to form a wrinkle-free sealing band at least 1 millimeter in length against a patient's tracheal wall when fully inflated; and a respective wrinkled portion wherein a widest fully inflated diameter of the wrinkled portion of the first tapered section and a widest fully inflated diameter of the wrinkled portion of the second tapered section are greater than the tracheal diameter such that at least one of the respective wrinkled portions is configured to form a wrinkled band against a patient's tracheal wall when inflated. a respective sealing portion comprising a fully inflated cuff diameter that is substantially equal to a tracheal diameter when the cuff is fully inflated such that at least one of the respective sealing portions is configured to form a wrinkle-free sealing band at least 1 millimeter in length against a patient's tracheal wall when fully inflated; and a respective wrinkled portion wherein a widest fully inflated diameter of the wrinkled portion of the first tapered section and a widest fully inflated diameter of the wrinkled portion of the second tapered section are greater than the tracheal diameter such that at least one of the respective wrinkled portions is configured to form a wrinkled band against a patient's tracheal wall when inflated. <EOS>
