        AngioDynamics Reports Fiscal First Quarter 2010 Financial Results

o     Net Sales Increase 13% to $50.1 Million
o     Net Income of $2.1 Million, or $0.09 EPS vs. $0.09 EPS in Q1FY09
o     Conference Call Begins Today at 4:30 p.m. Eastern Time


QUEENSBURY, N.Y. October 6, 2009 -- AngioDynamics (NASDAQ: ANGO), a leading
provider of innovative medical devices for minimally-invasive treatment of
cancer and peripheral vascular disease, today reported financial results for the
fiscal first quarter ended August 31, 2009.

Net sales in the first quarter were $50.1 million, a 13% increase over the $44.3
million reported in the first quarter a year ago. Gross margin was 60.2%
compared with 61.9% a year ago, with the decline primarily attributable to
product mix, material cost increases, a competitive pricing environment and
utilization factors. Operating income was $3.6 million in the quarter compared
with $3.8 million a year ago. Net income in the first quarter was $2.1 million
or $0.09 per share compared with $2.2 million, or $0.09 per share a year ago.
The decline in net income is primarily attributable to increased operating
expenses associated with sales and marketing programs and the Company's
continuing investment in irreversible electroporation (IRE) technology.

AngioDynamics reported cash and investments of $68.8 million and long-term debt
of $6.7 million at August 31, 2009.

Peripheral Vascular sales increased by 14% from the first quarter a year ago to
$21.1 million, and included sales of the Benephit(R) renal infusion system
acquired from FlowMedica in January 2009, as well as the sales from the
acquisition of Diomed assets since June 17, 2008. Access sales were $16.2
million in the quarter, an increase of 3% from the first quarter a year ago, and
Oncology/Surgery sales grew 25% to $12.8 million from the first quarter a year
ago.

"We made early progress in some of the areas of focus we established for the
company, yet have hard work ahead of us," said Jan Keltjens, President & CEO.
"Our sales growth for the quarter was driven by our Oncology/Surgery business
unit, as well as our laser vein ablation, or VenaCure EVLT(TM), product line.
VenaCure EVLT sales benefited from the increased focus of our commercial team
and the fundamental strength of our NeverTouch(R) technology.

"Our gross margin was impacted by sales mix, pricing pressures and cost
increases on certain purchased products," continued Mr. Keltjens. "We are
addressing this through our stated focus on manufacturing excellence and
inventory management. We believe this focus will result in gross margin
improvement and lower inventory levels beginning in the second half of the
fiscal year. In addition, our focus on innovation keeps us on schedule to launch
an additional seven new products, for a total of 11, by the end of the fiscal
year."

Highlights of the quarter and more recent activities include the following:

o     Shawn P. McCarthy was named Senior Vice President and General Manager of
      the Company's Peripheral Vascular Business Unit. Mr. McCarthy was formerly
      Vice President of Marketing at Cordis, a division of Johnson & Johnson.

o     NanoKnife(R) continues to be utilized by physicians at various
      institutions who have treated an additional 20 patients since mid-July.
      The total number of patients treated to date by the NanoKnife at eight
      centers now stands at 86. Procedures have been performed in five organs
      (prostate, liver, lung, kidney and lymph nodes). In all cases the safety
      profile for this non-thermal ablation technology remains impressive.
      NanoKnife IRE sales were $74,000 in the first quarter.

o     The IRE development program is making steady progress with an
      investigational device exemption (IDE) application for a focal prostate
      cancer study submitted to the FDA and for which we are in the process of
      responding to additional questions from the agency. In addition, an IDE
      application for a pancreatic cancer study is scheduled for FDA submission
      before the end of this calendar year. Pre-clinical work on lung and whole
      gland prostate are underway while pre-clinical work for pancreatic, focal
      prostate and liver studies are either complete or in the process of being
      completed this calendar year.

o     Launched the Benephit PROVIDE registry, an independently managed
      comprehensive clinical registry. It is designed to gather data on the
      clinical use of the Benephit renal infusion system by approximately 2,100
      patients during the next several years.

o     Commenced commercial shipments of the StarBurst(R) XLi-enhanced Semi-Flex
      probe, the first radiofrequency ablation device specifically designed to
      deliver a 7cm ablation of a tumor in a single placement during Computed
      Tomography-aided procedures.

o     Commenced commercial shipments of the DuraMax(TM) stepped chronic dialysis
      catheter. This new catheter is the first internally developed and
      manufactured dialysis catheter introduced by the Company. DuraMax
      incorporates AngioDynamics Curved Tip(TM) Catheter Technology, a design
      platform employed to provide higher blood flow and lower recirculation,
      and to reduce the potential for clots.

o     A study, published in the July edition of Endovascular Today by Dr. Lowell
      Kabnick, Director of New York University Vein Center and Associate
      Professor of Surgery at the Division of Vascular Surgery at NYU Medical
      Center, that compared treatments of varicose veins with a bare-tip laser
      fiber against the new covered-tip VenaCure EVLT NeverTouch laser fiber
      showed easier postoperative recovery, reduced bruising and other benefits
      from the NeverTouch treatment.

Fiscal 2010 Guidance

The Company revised its outlook for fiscal 2010 to the following:

      o     Net sales in the range of $211 million to $215 million, an increase
            of 8-10% over fiscal 2009 net sales (an increase from previous
            guidance of $209 million to $215 million)
      o     Gross margin in the range of 61-62% of net sales
      o     GAAP operating income in the range of $18 million to $20 million, an
            increase of 12-24%
      o     EBITDA in the range of $30 million to $32 million, an increase of
            8-15%
      o     GAAP EPS in the range of $0.45 to $0.47, inclusive of a $0.24 EPS
            impact from IRE investments (an increase from previous guidance of
            $0.43 to $0.47)

Use of Non-GAAP Measures

Management uses non-GAAP measures to establish operational goals, and believes
that non-GAAP measures may assist investors in analyzing the underlying trends
in AngioDynamics' business over time. Investors should consider these non-GAAP
measures in addition to, not as a substitute for or as superior to, financial
reporting measures prepared in accordance with GAAP. In this news release,
AngioDynamics has reported non-GAAP EBITDA (income before interest, taxes,
depreciation and amortization). Management uses this measure in its internal
analysis and review of operational performance. Management believes that this
measure provides investors with useful information in comparing AngioDynamics'
performance over different periods. By using this non-GAAP measure, management
believes that investors get a better picture of the performance of
AngioDynamics' underlying business. Management encourages investors to review
AngioDynamics' financial results prepared in accordance with GAAP to understand
AngioDynamics' performance taking into account all relevant factors, including
those that may only occur from time to time but have a material impact on
AngioDynamics' financial results. Please see the tables that follow for a
reconciliation of Operating Income to non-GAAP measures.
