Accounting Policies [Abstract]
Consolidated Condensed Financial Statements	CONSOLIDATED CONDENSED FINANCIAL STATEMENTS The consolidated condensed balance sheet as of November 30, 2015, the consolidated condensed statement of stockholders’ equity and the consolidated condensed statement of cash flows for the six months ended November 30, 2015 and the consolidated condensed statements of income (loss) and the consolidated condensed statements of comprehensive income (loss) for the three and six months ended November 30, 2015 and 2014 have been prepared by us without audit. The consolidated condensed balance sheet as of May 31, 2015 was derived from audited consolidated condensed financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary to state fairly the financial position, changes in stockholders’ equity and comprehensive income, results of operations and cash flows as of and for the period ended November 30, 2015 (and for all periods presented) have been made. The unaudited interim consolidated condensed financial statements for the three and six months ended November 30, 2015 and November 30, 2014 include the accounts of AngioDynamics, Inc. and its wholly owned subsidiaries, collectively, the “Company”. All intercompany balances and transactions have been eliminated. Recent Developments During the second quarter of fiscal 2016, Mark Frost resigned as Executive Vice President and Chief Financial Officer (CFO). Michael Trimarchi, Vice President and Global Controller, will assume the responsibilities as principal accounting officer of the company and will serve as interim CFO. The Company is in the process of identifying a permanent successor. On December 18, 2015, President Obama signed into law H.R. 2029, the “Consolidated Appropriations Act, 2016”, which includes a two-year moratorium on the medical device excise tax, effective January 1, 2016. The 2.3 percent tax on sales of medical devices (except certain devices sold at retail) was enacted as part of the Affordable Care Act in 2010 and applied to device sales beginning on January 1, 2013. Absent further legislative action, the tax will be automatically be reinstated for medical device sales starting on January 1, 2018. As presented on our Statements of Income (Loss) we have incurred $11.6 million cumulatively since the enactment of the tax on January 1, 2013 through the November 30, 2015, our second quarter of fiscal 2016. Our third quarter will include one month of the tax prior to the two year moratorium. In the absence of this tax, the company will seek opportunities to further invest in growth drivers to create long-term shareholder value. On November 17, 2015, the Company received a letter from the FDA closing out the warning letter the Company received from FDA in January 2011 regarding certain promotional activities related to the NanoKnife System. On November 25, 2015, the Company received letters from the FDA closing out the warning letters the Company received from FDA in May 2011 related to the Company’s Queensbury facility and in November 2014 related to the Company’s Glens Falls facility. These close out letters resolved all outstanding warning letters against the Company.
