VI of the Company&#8217;s Amended and Restated Bylaws, a copy of which is filed as

threatened, pending or completed action, suit or proceeding, by or in the right
of the Company, by reason of the fact that such person is or was an officer or

director, officer, employee or agent of another corporation, partnership, joint

DGCL.&#160;&#160;In addition, Article VI also provides for advancement to an
indemnitee of expenses (including attorneys&#8217; fees) incurred in defending the
proceeding in advance of its final disposition, subject to the delivery of any
required undertaking to repay the advancement in the event that the indemnitee
is ultimately found not entitled to such indemnification.</font></div>

145 of the DGCL authorizes, inter alia, a corporation to indemnify any person
(&#8220;indemnitee&#8221;) who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, by or in the right
of the corporation, by reason of the fact that such person is or was an officer
or director of such corporation, or is or was serving at the request of such
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. The amounts paid in
settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding, provided that he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. A Delaware corporation may
indemnify past or present officers and directors of such corporation or of
another corporation or other enterprise at the former corporation&#8217;s request, in
an action by or in the right of the corporation to procure a judgment in its
favor under the same conditions, except that no indemnification is permitted
without judicial approval if such person is adjudged to be liable to the
corporation. Where an officer or director is successful on the merits or
otherwise in defense of any action referred to above, or in defense of any
claim, issue or matter therein, the corporation must indemnify him against the
expenses (including attorney&#8217;s fees) which he actually and reasonably incurred
in connection therewith. Section 145 further provides that any indemnification
shall be made by the corporation only as authorized in each specific case upon a
determination by the (i) stockholders, (ii) board of directors by a majority
vote of a quorum consisting of directors who were not parties to such action,
suit or proceeding or (iii) independent counsel if a quorum of disinterested
directors so directs.&#160;&#160;Section 145 provides that indemnification
pursuant to its provisions is not exclusive of other rights of indemnification
to which a person may be entitled under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise.</font></div>

against such liability under the provisions of Section 145. Cyberonics intends

Indemnification of Directors and
Officers
Article
VIII of Cyberonics' Certificate of Incorporation, a copy of which is filed as
Exhibit 4.1, provides that the Company's directors shall be indemnified to the
fullest extent permitted by the Delaware General Corporation Law (the
"DGCL").
Article
VI of the Company's Amended and Restated Bylaws, a copy of which is filed as
Exhibit 4.2, provides that the Company shall indemnify any person (an
"indemnitee") who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, by or in the right
of the Company, by reason of the fact that such person is or was an officer or
director of the Company, or is or was serving at the request of the Company as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, to the fullest extent permitted by the
DGCL.  In addition, Article VI also provides for advancement to an
indemnitee of expenses (including attorneys' fees) incurred in defending the
proceeding in advance of its final disposition, subject to the delivery of any
required undertaking to repay the advancement in the event that the indemnitee
is ultimately found not entitled to such indemnification.
Section
145 of the DGCL authorizes, inter alia, a corporation to indemnify any person
("indemnitee") who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, by or in the right
of the corporation, by reason of the fact that such person is or was an officer
or director of such corporation, or is or was serving at the request of such
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. The amounts paid in
settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding, provided that he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. A Delaware corporation may
indemnify past or present officers and directors of such corporation or of
another corporation or other enterprise at the former corporation's request, in
an action by or in the right of the corporation to procure a judgment in its
favor under the same conditions, except that no indemnification is permitted
without judicial approval if such person is adjudged to be liable to the
corporation. Where an officer or director is successful on the merits or
otherwise in defense of any action referred to above, or in defense of any
claim, issue or matter therein, the corporation must indemnify him against the
expenses (including attorney's fees) which he actually and reasonably incurred
in connection therewith. Section 145 further provides that any indemnification
shall be made by the corporation only as authorized in each specific case upon a
determination by the (i) stockholders, (ii) board of directors by a majority
vote of a quorum consisting of directors who were not parties to such action,
suit or proceeding or (iii) independent counsel if a quorum of disinterested
directors so directs.  Section 145 provides that indemnification
pursuant to its provisions is not exclusive of other rights of indemnification
to which a person may be entitled under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise.
Section
145 of the DGCL also empowers Cyberonics to purchase and maintain insurance on
behalf of any person who is or was an officer or director of Cyberonics against
liability asserted against or incurred by him in any such capacity, whether or
not Cyberonics would have the power to indemnify such officer or director
against such liability under the provisions of Section 145. Cyberonics intends
to purchase and maintain a directors' and officers' liability policy for such
purposes.

Undertakings
The
undersigned registrant hereby undertakes:
(1)
To
      file, during any period in which offers or sales are being made, a
      post-effective amendment to this Registration
  Statement:
(a)
To
      include any prospectus required by Section 10(a)(3) of the Securities
      Act;
(b)
To
      reflect in the prospectus any facts or events arising after the effective
      date of this Registration Statement (or the most recent post-effective
      amendment thereof) which, individually or in the aggregate, represent a
      fundamental change in the information set forth in this Registration
      Statement.  Notwithstanding the foregoing, any increase or
      decrease in volume of securities offered (if the total dollar value of
      securities offered would not exceed that which was registered) and any
      deviation from the low or high end of the estimated maximum offering range
      may be reflected in the form of prospectus filed with the Commission
      pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
      price represent no more than a 20 percent change in the maximum aggregate
      offering price set forth in the "Calculation of Registration Fee" table in
      the effective registration statement;
and
(c)
To
      include any material information with respect to the plan of distribution
      not previously disclosed in this Registration Statement or any material
      change to such information in this Registration
  Statement;
provided, however
, that
paragraphs (1)(a) and (1)(b) do not apply if the information required to be
included in a post-effective amendment by those paragraphs is contained in
periodic reports filed with or furnished or furnished to the Commission by the
registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934 (the "Exchange Act") that are incorporated by reference in this
Registration Statement.
(2)
That,
      for the purpose of determining any liability under the Securities Act,
      each such post-effective amendment shall be deemed to be a new
      registration statement relating to the securities offered therein, and the
      offering of such securities at that time shall be deemed to be the initial
      bona fide offering thereof.
(3)
To
      remove from registration by means of a post-effective amendment any of the
      securities being registered which remain unsold at the termination of the
      offering.
(4)
That,
      for purposes of determining any liability under the Securities Act, each
      filing of the registrant's annual report pursuant to Section 13(a) or
      Section 15(d) of the Exchange Act (and, where applicable, each filing of
      an employee benefit plan's annual report pursuant to Section 15(d) of the
      Exchange Act) that is incorporated by reference in the Registration
      Statement shall be deemed to be a new registration statement relating to
      the securities offered therein, and the offering of such securities at
      that time shall be deemed to be the initial bona fide offering
      thereof.
(5)
Insofar
      as indemnification for liabilities arising under the Securities Act may be
      permitted to directors, officers and controlling persons of the
      registrant, the registrant has been advised that in the opinion of the
      Commission such indemnification is against public policy as expressed in
      the Securities Act and is, therefore, unenforceable.  In the
      event that a claim for indemnification against such liabilities (other
      than the payment by the registrant of expenses incurred or paid by a
      director, officer or controlling person of the registrant in the
      successful defense of any action, suit or proceeding) is asserted by such
      director, officer or controlling person in connection with the securities
      being registered, the registrant will, unless in the opinion of its
      counsel the matter has been settled by controlling precedent, submit to a
      court of appropriate jurisdiction the question whether such
      indemnification by it is against public policy as expressed in the
      Securities Act and will be governed by the final adjudication of such
      issue.

Pursuant
to the requirements of the Securities Act of 1933, the registrant certifies that
it has reasonable grounds to believe that it meets all of the requirements for

Cyberonics,
Inc.
100
Cyberonics Boulevard
Houston,
Texas 77058
RE:
Registration Statement on Form S-8
Ladies
and Gentlemen:
We have
acted as counsel for Cyberonics, Inc., a Delaware corporation (the "
Company
"), with respect to
certain legal matters in connection with the registration by the Company under
the Securities Act of 1933 of the offer and sale of up to 2,100,000 shares of
common stock, par value $0.01 per share (the "
Shares
"), pursuant to the
Cyberonics, Inc. 2009 Stock Plan (the "
Plan
").
In
connection with the opinion expressed herein, we have examined, among other
things, (i) the Company's Amended and Restated Certificate of Incorporation
and Amended and Restated Bylaws, (ii) the records of corporate proceedings
that have occurred prior to the date hereof with respect to the Shares, and
(iii) the registration statement on Form S-8 filed in connection with the
Shares (the "
Registration
Statement
").  We have also reviewed such questions of law as we
have deemed necessary or appropriate.  As to matters of fact relevant
to the opinion expressed herein, and as to factual matters arising in connection
with our examination of corporate documents, records and other documents and
writings, we relied upon certificates and other communications of corporate
officers of the Company, without further investigation as to the facts set forth
therein.
Based
upon the foregoing, we are of the opinion that (i) the issuance of the Shares
has been duly authorized by the Company and (ii) when the Shares have been
issued in accordance with the provisions of the Plan, the Shares will be validly
issued, fully paid and nonassessable.
The
foregoing opinions are limited in all respects to the General Corporation Law of
the State of Delaware (including the applicable provisions of the Delaware
Constitution and the reported judicial decisions interpreting these laws) and
the federal laws of the United States of America, and we do not express any
opinions as to the laws of any other jurisdiction.
We hereby
consent to the statements with respect to us under the heading "Legal Matters"
in the prospectus incorporated by reference in the Registration Statement and to
the filing of this opinion as an exhibit to the Registration Statement, but we
do not thereby admit that we are within the class of persons whose consent is
required under the provisions of the Securities Act of 1933 or the rules and
regulations of the Securities and Exchange Commission issued
thereunder.
Very
      truly yours,
