Abstract:
1. A tracheostomy device, comprising: a handle; an inflating tube; a wire guide tube; an intermediate portion to sustain the inflating tube and the wire guide tube; a tracheal tube surrounding the intermediate portion; and a dilating balloon, being inflatable through the inflating tube, the balloon having a proximal portion and a distal portion, each of the balloon, the proximal portion of the balloon and the distal portion of the balloon having a respective proximal end and a respective distal end, the distal end of the proximal portion and the proximal end of the distal portion being separated by a major diameter, the proximal portion being active during dilation such that the proximal portion of the balloon forms a reverse truncated cone shape, wherein, when the balloon is inflated, the balloon has a base diameter at the major diameter which is larger than the proximal portion of the balloon, the shape of the balloon is tightly connected to the tracheal tube such that the proximal portion of the balloon is partially inside a lumen of the tracheal tube, and the proximal portion of the balloon outside the tracheal tube is larger in diameter than the tracheal tube such that, when the balloon is inflated, the dilating balloon causes a thrust to move forward the device in a trachea of a patient, a distal portion of the inflating tube is connected to the distal end of the balloon; and the distal portion of the balloon has a base diameter at the major diameter which is larger than a base diameter at a remainder of the distal portion of the balloon when the balloon is inflated; wherein the inflating tube has an end forming an opening through which a dilation force is first delivered to the distal portion of the balloon to inflate the balloon; wherein, outside of the tracheal tube, the balloon is devoid of a tubular section of constant diameter when the balloon is inflated.
