Debt Disclosure [Abstract]
Long Term Debt	NOTE F – LONG TERM DEBT New Credit Agreement On September 19, 2013, we entered into a Credit Agreement (the “Credit Agreement”) with the lenders party thereto, JPMorgan Chase Bank, N.A., as administrative agent, Bank of America, N.A. and Keybank National Association as co-syndication agents, and J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Keybank National Association as joint bookrunners and joint lead arrangers. The Credit Agreement provides for a $100 million senior secured term loan facility (“Term Loan”) and a $100 million senior secured revolving credit facility, which includes up to a $20 million sublimit for letters of credit and a $5 million sublimit for swingline loans (the “Revolving Facility”, and together with the TermLoan, the “Facilities”). The proceeds of the Term Loan and a portion of the proceeds of the Revolving Facility were used to repay our Credit Agreement (the “Existing Credit Agreement”) dated as of May 22, 2012 with the lenders party thereto, JPMorgan Chase Bank, N.A., as administrative agent, Bank of America, N.A. and Keybank National Association as co-syndication agents, and J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Keybank National Association as joint bookrunners and joint lead arrangers. The proceeds of the Revolving Facility may be used for general corporate purposes of AngioDynamics and its subsidiaries. The Facilities have a five year maturity. The Term Loan has a quarterly repayment schedule equal to 5%, 5%, 10%, 15% and 65% of its principal amount in years one through five. Interest on both the Term Loan and Revolving Facility will be based on a base rate or Eurodollar rate plus an applicable margin which increases as our total leverage ratio increases, and with the base rate and Eurodollar rate having ranges of 0.50% to 1.25% and 1.50% to 2.25% respectively. After default, the interest rate may be increased by 2.0%. The Revolving Facility will also carry a commitment fee of 0.20% to 0.35% per annum on the unused portion. Our obligations under the Facilities are unconditionally guaranteed, jointly and severally, by our material direct and indirect domestic subsidiaries (the “Guarantors”). All obligations of AngioDynamics and the Guarantors under the Facilities are secured by first priority security interests in substantially all of the assets of AngioDynamics and the Guarantors. In June 2012, we entered in an interest rate swap agreement, (the “Swap Agreement”), with an initial notional amount of $100 million, to limit the effect of rising of interest rates. The Swap Agreement, which qualified for hedge accounting under authoritative guidance, was a contract to exchange floating interest rate payments for fixed interest rate payments on the outstanding balance of the loan over the life of the agreement without the exchange of the underlying notional amounts. The Swap Agreement provides for a fixed rate of 0.74% above the applicable rate provided for in the Credit Agreement. On September 19, 2013, we borrowed $100 million under the Term Facility and approximately $41.4 million under the Revolving Facility to repay the Existing Credit Agreement. As of November 30, 2013, $98.8 million and $41.4 million were outstanding under the Term Facility and Revolving Facility, respectively. The Credit Agreement includes customary representations, warranties and covenants, and acceleration, indemnity and events of default provisions, including, among other things, two financial covenants. The first financial covenant requires us to maintain, as of the end of each of our fiscal quarters, a ratio of (i) consolidated EBITDA minus consolidated capital expenditures to (ii) consolidated interest expense paid or payable in cash plus scheduled principal payments in respect of indebtedness under the Credit Agreement of not less than 1.35 to 1.00. The second financial covenant requires us to maintain, as of the end of each of our fiscal quarters, a ratio of consolidated total indebtedness to consolidated EBITDA of not greater than 3.75 to 1.00. We were in compliance with both covenants as of November 30, 2013. On September 19, 2013, we repaid all amounts owed under the Existing Credit Agreement, and as a result, the Existing Credit Agreement was terminated. Pursuant to the terms of the Existing Credit Agreement, we had the option to repay this facility at any time prior to the maturity date without penalty.
