Tracheal tube and methods related thereto
First Claim
1. A tracheal tube for insertion into the trachea of a patient, comprising a tube portion having a distal end and a permanent magnet associated with the tube portion, wherein the permanent magnet is associated with the tube portion at a distance from the distal end such that, when the tube portion is inserted into the trachea of the patient and the permanent magnet is positioned immediately posterior to the patient'"'"'s cricothyroid ligament, the distal end is positioned within the trachea at a proper depth.

Abstract
There is disclosed a tracheal tube for insertion into the trachea of a patient. The tracheal tube includes a tube portion having a distal end, and a signal source associated with the tube portion at a predefined distance from its distal end. The tracheal tube is inserted into the trachea such that the signal source is immediately posterior to the patient'"'"'s cricothyroid ligament. Methods related to confirming proper placement of the tracheal tube by detecting the signal source immediately posterior to the patient'"'"'s cricothyroid ligament are also disclosed.
