   2.                                                   We note your statement
on page 2:    We continue to develop a substantial body of clinical
                                                        evidence to demonstrate
the safety and efficacy of the Genio system    and your statement
                                                        on page 4 referring to
the Genio system as a clinically proven solution. You also refer on

Page 2
         page 5 to the Genio system being a    [s]afe, effective and
patient-centric therapeutic
         option    that    demonstrated compelling safety and effectiveness
data.    Please revise these
         statements and all similar statements throughout your prospectus that
state or imply that
         your product candidates are safe or effective as these determinations
are solely within the
         authority of the FDA and comparable regulatory bodies in other
jurisdictions.
3.       On page 2 you state:    We believe that positive results from this
trial may eliminate the
         need for Genio system patients to undergo the DISE procedure prior to
implantation of the
         Genio system, thereby leading to a potential indication expansion in
Europe.    Please
         revise to balance these statements concerning the need to undergo the
DISE
         procedure given on page 103 you indicated a different procedure would
still be required
         with the Genio system, specifically that a post-surgery sleep study
will need to be
         conducted to optimize the Genio system device, or advise.
4.       We note your statement on page 3 that you plan to investigate and
provide new
         neurostimulation technologies for OSA patients through your
partnership with Vanderbilt
         University. Please revise to describe this partnership.

5.       Please revise page 3 to explain how you calculated an $11 billion
European, Australian

         Additionally, explain how you estimated non-compliance rates. Lastly,
you state that
            approximately 70% of those non-compliant patients are eligible for
hypoglossal nerve
         stimulation based on their anatomical characteristics.    Please also
revise to explain in the
         Summary the anatomical limitations of your device or hypoglossal nerve
stimulation
         devices generally.
