Airway assembly for tracheal intubation
In some embodiments, an airway assembly may be used in a procedure that requires tracheal intubation. The airway assembly may include a first conduit, a sleeve, and a stent. The first conduit and the sleeve may be relatively flexible, facilitating insertion of the airway assembly in a body lumen (e.g., an air passage way). The first conduit may function to deliver gases (e.g., air) to the body lumen and consequently the patient. The first conduit may be positioned in the sleeve during use. The sleeve may be removably coupled to the first conduit. In certain embodiments, a sleeve may function to inhibit a stent from expanding until desired. In some embodiments, an elongated member may be positionable in the first conduit. The elongated member may be configurable to substantially retain a new shape upon deformation. The stent may be coupled towards the distal end of the first conduit. The stent may function to inhibit the body lumen from collapsing. In certain embodiments, a stent may function to inhibit the body lumen from collapsing without exerting unnecessary outward pressures on the inner surface of the body lumen.
1. A method for endotracheal intubation, the method comprising the steps of:
inserting at least a distal end of an airway assembly in an air passage selected from one of the trachea, right bronchus or left bronchus of a patient, wherein the airway assembly comprises:
a first elongated tubular conduit with a proximal end and a distal end, wherein the distal end of the first elongated tubular conduit is positionable within one of the trachea, right bronchus or left bronchus of the patient and the proximal end of the first elongated tubular conduit remains outside the patient's body, and wherein the first elongated tubular conduit is configurable to deliver gas to the patient's lungs;
a stent having at least a proximal end that is fixedly coupled to the distal end of the first elongated tubular conduit, wherein the stent is formed from a material that is less flexible than the first tubular conduit and is configurable to expand into contact with and to inhibit collapse of at least a portion of the trachea, right bronchus or left bronchus; and
a sleeve, wherein at least a portion of the distal end of the first elongated tubular conduit and at least a portion of the stent are positionable in the sleeve, and wherein the sleeve inhibits the stent from expanding until the sleeve is removed from the stent;
retracting at least a portion of the sleeve substantially surrounding the stent; and
delivering fluids through the proximal end of the first elongated tubular conduit into the air passage.
2. The method of claim 1 , further comprising the step of: positioning at least a portion of a stent expansion device in the stent.
3. The method of claim 1 , further comprising the step of: inserting the distal end of the airway assembly through a non-natural opening in the air passage.
4. The method of claim 1 , further comprising the step of: inserting the distal end of the airway assembly through a natural opening in the air passage.
5. The method of claim 1 , further comprising the steps of: positioning at least a portion of a stent expansion device in the stent; and expanding the stent.
6. The method of claim 1 , further comprising the step of: positioning an elongated member in the first elongated tubular conduit, wherein the elongated member is deformable from an original shape into a new shape and substantially retains the new shape upon deformation of the elongated member.
7. The method of claim 1 , further comprising the steps of: positioning an elongated member in the first elongated tubular conduit, wherein the elongated member is deformable from an original shape into a new shape and substantially retains the new shape upon deformation of the elongated member; and deforming the elongated member so as to facilitate insertion of the distal end of the first elongated tubular conduit in the air passage.
