How Alaxo Nasal Stents Work


There are two different product lengths which splint either the anterior nasal cavity only [AlaxoLito Nasal Stent 2”] or the full length nasal passage [AlaxoLito Nasal Stent 3” and AlaxoLito Sport Nasal Stent 3”] (see Figs. 1a+b).

The AlaxoLito nasal stents are medical devices for the improvement of nasal breathing. Potential causes of decreased nasal breathing are nasal alar collapse, nasal valve collapse or turbinate hyperplasia.


The design of the stent braid is made from shape memory metal nitinol. It has a ball-shaped widening that gets positioned at the nasal valve, while the cylindrical longer portion opens the turbinates. 

The stent has an opening force to support the nasal alar and valve, while splinting the turbinates.  This leads to a healthy diameter of the airway and an improvement in nasal breathing.  The nasal tissue does not get overstretched and there is no mucosal irritation. 

How to use

Prior to insertion, the AlaxoLito Nasal Stent is pulled into a thin introduction tube (see Fig. 2).  This is then introduced horizontally into the nose (in the middle or lower nasal passage).  Subsequent retraction of the introduction tube from the nose leads to self-expansion of the nitinol braid.  The ball-shaped widening is located at the nasal valve (see arrow in right photo in Fig. 3).  The cylindrical portion of the stent splints the anterior (AlaxoLito 2”) or the full (AlaxoLito 3”) nasal passage.  

Stents are used in both the right and left nostril. The stents are easily self-inserted by patients and the design makes the stents hardly visible in the nostrils. (see Fig. 3).

Patient Experience

The use of the AlaxoLito Nasal Stents leads to a significant improvement in nasal breathing, leading to a more relaxing sleep because of increased oxygen supply. 

Snoring is usually completely abolished.

A Natural Breathing Experience


The AlaxoStent is an FDA registered medical device.  It has been clinically tested to treat obstructive sleep apnea (OSA) and snoring.  This medical device can be inserted by the patient into his nose and throat at night, and removed in the morning. 

Complementing traditional treatments for OSA such as the CPAP, the AlaxoStent offers a new non-surgical and effective treatment.


The design of the stent braid is made from shape memory metal nitinol. It has a ball-shaped widening that gets positioned at the nasal valve, while the cylindrical longer portion opens the turbinates.

How to use

The nitinol braid [1] is compressed into a thin tube [2] (see Fig. 4) before introduction into one nostril. This tube is then slowly introduced through one nasal passage to the throat. When released from the introduction tube, the nitinol braid expands and attaches to the wall of the throat. This leads to the stent preventing collapse of the airway by mechanically splinting the throat. 

The AlaxoStent leads to a continuous air passage which enables unobstructed breathing and abolishes sleep apnea.  It is positioned at the soft palate, and prevents collapse of the soft tissue in the velopharynx. (see Fig. 5)

Patient Experience

The AlaxoStent was developed in conjunction with OSA patients, to enhance the patient experience. With the AlaxoStent, you can move freely with the stent inserted and it is visually inconspicuous.

PLUS the entire bedroom is peaceful without the noise of the CPAP pump.

Typically snoring is completely abolished, and the patient maintains the ability to breathe naturally, not artificially as it does with the CPAP.  There is no pump or electric current required, and the stent is quite small.  This offers a particular advantage when travelling. 

The emotional hurdle of introducing the stent through the nasal passage into the throat is comparable with using contact lenses for the first time.  With education and a short training by the doctor, the patient can self-insert the stent safely and quickly.
