Item  1.  Security  and  Issuer

     The  Schedule  13D  filed  with  the  Securities and Exchange Commission on
January  7,  2007,  by  the  Reporting Persons (together with the amendments set
forth below, the "Schedule 13D") with respect to the shares of Common Stock, par
value  $0.01  (the  "Shares"),  issued  by  Cyberonics,  Inc. (the "Issuer"), as
amended  by  the  First  Amendment  to Schedule 13D dated April 26, 2011 and the
Second Amendment to Schedule 13D dated May 9, 2011, is hereby further amended to
furnish  the  additional  information  set forth herein. This Third Amendment to
Schedule  13D  reports  that  the  Reporting Persons ceased to be the beneficial
owner  of  more  than  five  percent  (5%)  of  the  Shares on June 1, 2011. All
capitalized  terms  contained  herein  but  not otherwise defined shall have the
meanings  ascribed  to  such  terms  in  the  Schedule  13D.

Item 3. Source and Amount of Funds or Other Consideration

     Item  3  of  the  Schedule  13D  is  hereby  amended by replacing it in its
entirety  with  the  following:

     The  Reporting  Persons  hold,  in  the  aggregate,  1,266,409  Shares. The
aggregate  purchase  price  of  the  Shares  purchased  by the Reporting Persons
collectively  was  $24.6  million  (including  commissions  and premiums for the
options  to  purchase  Shares).  The  source of funding for the purchase was the
general working capital of the respective purchasers. The Shares are held by the
Reporting Persons in margin accounts together with other securities. Such margin

of  the  Shares  purchased  by the Reporting Persons was obtained through margin
borrowing.

     Item  5  of  the  Schedule  13D  is  hereby  amended by replacing it in its
entirety  with  the  following:

     (a)  The  Reporting  Persons  may  be  deemed  to  beneficially own, in the
