Item 1.

This Amendment No. 1 to Schedule 13D (“Amendment No. 1”) relates to the Common Stock, $0.001 par value per share (the “Common Stock”), of AtriCure, Inc., a Delaware corporation (the “Company”), which has its principal executive offices at 6217 Centre Park Drive, West Chester, Ohio 45069.  This Amendment No. 1 amends and supplements, as set forth below, the information contained in items 1, 2, 3, 5 and 6 of the Schedule 13D filed by the Reporting Persons with respect to the Company on September 10, 2010 (as so amended, the “Schedule 13D”).  All capitalized terms used herein but not defined herein have the meanings set forth in the Schedule 13D.  Except as amended by this Amendment No. 1, all information contained in the Schedule 13D is, after reasonable inquiry and to the best of the Reporting Persons’ knowledge and belief, true, complete and correct as of the date of this Amendment No. 1.
   
Item 2.
Identity and Background
   
 
Item 2 of the Schedule 13D is hereby amended by adding the following as the second line thereof:

Discovery Equity Partners, L.P. (“Discovery Equity Partners”) is an Illinois limited partnership primarily engaged in the business of investing in securities.
   
Item 3.
Source and Amount of Funds or Other Consideration
   
 
Item 3 of the Schedule 13D is hereby amended to read in its entirety as follows:

The total purchase price for the 1,460,708 shares of Common Stock beneficially owned by Discovery Group and Messrs. Donoghue and Murphy as of September 26, 2010 was approximately $9,823,700, and the total purchase price for the 1,247,037 shares of Common Stock beneficially owned by Discovery Equity Partners was approximately $8,412,642.  The source of such funds was the assets of Discovery Equity Partners and another private investment partnership (collectively, the “Partnerships”) over which Discovery Group exercises discretionary investment management authority, including proceeds of marg in loans under margin loan facilities maintained in the ordinary course of business by the Partnerships with a broker on customary terms and conditions.  The Partnerships are the legal owner of all of the Common Stock beneficially owned by Discovery Group and Messrs. Donoghue and Murphy.
 
 
 

 
 
Item 5.
Interest in Securities of the Issuer
   
 
Item 5 of the Schedule 13D is hereby amended to read in its entirety as follows:
   
 
The information concerning percentages of ownership set forth below is based on 15,562,949 shares of Common Stock reported outstanding as of August 6, 2010 in the Company’s most recent Quarterly Report on Form 10-Q, for the period ended June 30, 2010.
 
   
 
Discovery Equity Partners beneficially owns 1,247,037 shares of Common Stock as of September 26, 2010, which represents 8.0% of the outstanding Common Stock.
   
 
Discovery Group beneficially owns 1,460,708 shares of Common Stock as of September 26, 2010, which represents 9.4% of the outstanding Common Stock.
 
   
 
Mr. Donoghue beneficially owns 1,460,708 shares of Common Stock as of September 26, 2010, which represents 9.4% of the outstanding Common Stock.
 
   
 
Mr. Murphy beneficially owns 1,460,708 shares of Common Stock as of September 26, 2010, which represents 9.4% of the outstanding Common Stock.
 
   
 
Discovery Group is the sole general partner of one of the Partnerships and has sole discretionary investment authority with respect to the other Partnership’s investment in the Common Stock.  Messrs. Donoghue and Murphy are the sole managing members of Discovery Group.  As a consequence, Discovery Group and Messrs.
