Abstract
The present invention relates to tracheal tubes which are used to introduce gasses or vapors along the trachea, such as by an anesthesiologist during the administration of anesthesia to a patient undergoing surgery. In particular, the present invention relates to a tracheal tube which includes a flexible portion that allows for movement of the proximal end relative to the distal end of the tracheal tube without creating stress at the proximal or distal ends. The tracheal tube according to the present invention allows 360.degree. access to the head and neck area of a patient, and allows for movement of the proximal end of the tracheal tube during a surgical procedure without requiring re-intubation.
