The AlaxoLito Nasal Stent is a medical device for
optimization of nasal breathing in case of nasal
congestion and for sports.
There are two different product lengths which splint
either the anterior nasal cavity only [AlaxoLito Nasal
Stent] or the full length nasal passage [AlaxoLito
Plus Nasal Stent and AlaxoLito Xtreme / Sport Nasal
Stent] (see Figs. 1a+b).

The product has been developed together with the ENT
physician Dr. Peter Renner (Cologne, Germany) and is
specifically adapted for application in the nasal cavity.
The smooth stent braid is made from the memory metal
nitinol. It has a ball-shaped widening which is positioned
at the nasal valve and a cylindrical longer section which
splints the turbinates. The AlaxoLito (top in photo) and
the AlaxoLito Plus, resp. (bottom in photo, see Fig. 2),
is self-applied to the nose by the patient, usually for
the period of sleep or e.g. during sports activities.

The stent has an opening force adapted to supporting the
nasal alar and nasal valve and to splinting of the
turbinates. Thereby a healthy diameter of the airway and a
very good therapeutic effect are achieved concurrent with
high wearing comfort. The nasal tissue is not
overstretched and no mucosal irritation occurs.
The AlaxoLito Xtreme / Sport Nasal Stent has a higher
opening force than the AlaxoLito Plus Nasal Stent and is
predominantly intended for use during sports.
The innovative concept of the AlaxoLito Nasal Stent for
the first time enables an efficient conservative therapy
of turbinate hyperplasia and also nasal alar collapse. As
a result wellness and health of a large number of patients
can be improved.
For application the AlaxoLito Nasal Stent is pulled into a
thin introduction tube (see Fig. 2) which then is
introduced horizontally into the nose (in the middle or
inferior nasal passage). Subsequent retraction of the
introduction tube from the nose leads to self-expansion of
the nitinol braid. The ball-shaped widening locates
directly at the nasal valve (see arrow in right photo in
Fig. 3). The cylindrical section splints the anterior
(AlaxoLito) or the full (AlaxoLito Pus), resp., nasal
passage. Usually each one stent is introduced into the
right and the left nostril. Simple handling of the
AlaxoLito Nasal Stent allows easy self-application by the
The nasal stent is optimized in its design so that it is
hardly visible in the nostril.

alar compared to nostril without AlaxoLito
Due to the shape of the nitinol braid stable
positioning within the nose, secured against shifting
during application and sleep, is achieved. The nasal
valve and the nasal alar are efficiently splinted
(Fig. 3) but without any expansion by strong pressure.
Therefore no uncomfortable feeling of pressure arises.

The AlaxoLito nitinol braid is well visible in magnetic
resonance imaging (MRI) in the nasal cavity and the nasal
passage (Fig. 5).

Dr. Peter Renner tested the AlaxoLito Nasal Stent by
rhinomanometry for its efficacy in increasing nasal
flow with 10 patients with decreased nasal breathing
Fig. 6: Results of rhinomanometric testing of the
AlaxoLito Nasal Stent with 10 patients suffering
from decreased nasal breathing
On average the nasal flow of 245 ml/s was improved
by 123% and a value of 546 ml/s – which is normal
condition – was achieved. The maximal value recorded
for a single nasal passage was plus 724%. These
results demonstrate the power of the AlaxoLito Nasal
Stent to increase the nasal flow of patients from a
severely reduced level to a normal level so that
healthy nasal breathing is enabled.
Another test with 11 healthy persons proved
increase even of normal nasal flow by 47% on average
by use of the AlaxoLito Nasal Stent (Fig. 7).

AlaxoLito Nasal Stent with 11 healthy persons
Application of the AlaxoLito Nasal Stent leads to a
significant improvement of nasal breathing and
reduction of flow noise. Sleeping becomes more
healthy and relaxing as a consequence of the
improved oxygen supply.
Testing of the AlaxoLito during sports (road racing,
cross country skiing, mountain hiking) resulted in a
strongly enhanced condition. Its application during
endurance sports may lead to severely enhanced
performance of the sportsperson due to the improved
nasal breathing. It is known that nasal breathing
compared to mouth breathing increases the
transcutaneous oxygen partial pressure by ca. 10%
and that it stimulates the parasympathetic nerve
Likewise, first application tests in case of a
swollen nose demonstrated that with AlaxoLito nasal
breathing can be well restored, allowing for a calm
sleep of the user.
