QUEENSBURY, N.Y. July 16, 2009 -- AngioDynamics, Inc. (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 fourth quarter and year ended May 31, 2009. Financial results include the
acquisition of Diomed assets since June 17, 2008 and the acquisition of
FlowMedica assets since January 12, 2009, the dates of acquisition. In addition,
the Company announced plans to establish a corporate office near Albany, N.Y.

Net sales in the fourth quarter were $52.8 million, a 13% increase over the
$46.8 million reported in the fourth quarter a year ago. Gross margin in the
fourth quarter was 61.9% compared with 62.7% a year ago, with the decline
attributable to product mix. Operating income was $4.8 million in the fourth
quarter compared with $322,000 a year ago.

Net income in the fourth quarter was $2.9 million or $0.12 per share compared
with $519,000, or $0.02 per share a year ago. 2009 fourth quarter operating
results include $702,000 in certain non-recurring costs, which are primarily
attributable to the write-off of facility design and related costs associated
with a terminated project to build an office in Queensbury. In the fourth
quarter a year ago, the Company recorded a $6.8 million litigation provision.
Excluding the aforementioned two items, fourth quarter net income was $3.4
million or $0.14 per share compared with net income of $4.7 million or $0.19 per
share a year ago. The decline in net income is primarily attributable to
increased operating expenses associated with the Company's investments in
irreversible electroporation (IRE) technology and sales and marketing programs.

EBITDA (Non GAAP) was $7.8 million or $0.32 per share in the fourth quarter and
$2.8 million or $0.12 per share in the fourth quarter a year ago.

For the fiscal year ended May 31, 2009, net sales of $195.1 million increased
17% over the $166.5 million reported for the prior year; gross margin was 61.6%
in both years; operating income was $16.1 million compared with $16.2 million
for the prior year; net income was $9.9 million or $0.41 per share, compared
with $10.9 million or $0.45 per share for the prior year; and EBITDA (Non GAAP)
was $27.9 million or $1.14 per share, compared with $25.4 million or $1.04 per
share for the prior year.

AngioDynamics reported cash and investments of $68.2 million and long-term debt
of $6.8 million at May 31, 2009. The Company generated $6.9 million in cash flow
from operations in the fourth quarter, bringing cash flow from operations for
fiscal 2009 to $19.9 million.

In fiscal 2009, AngioDynamics began operating three business units: Peripheral
Vascular, Access and Oncology/Surgery. Peripheral Vascular sales were $22.5
million in the fourth quarter, an increase of 26% from the fourth quarter a year
ago, inclusive of the laser ablation products acquired from Diomed and the
Benephit(R) renal infusion system acquired from FlowMedica. Access sales were
$17.9 million in the quarter, a decrease of 1% from the fourth quarter a year
ago, and Oncology/Surgery sales grew 15% to $12.4 million from the fourth
quarter a year ago.

"While we made progress during the fourth quarter, our performance illustrates
the investments we are making in IRE and sales and marketing and the work to be
done to restore organic sales growth," said Jan Keltjens, President and CEO.
"Since early March, I've spent a great deal of time getting to know our team and
evaluating the Company's strengths and opportunities. We have begun implementing
several actions that I believe will improve future operating performance. We
have identified the business areas that can drive global growth and are moving
forward on streamlining the organization, increasing accountability, focusing
R&D efforts and creating a center of expertise for manufacturing and process
engineering. As a result, we are making plans to establish an office closer to
the Albany area. This new office will allow us to create needed manufacturing
and engineering capacity and focus at our Queensbury global supply chain hub.
Additionally, it will provide an attractive and more easily accessible location
for our marketing and R&D teams, while enhancing our ability to attract key
talent to drive our growth.

"We have also decided to accelerate our investments in developing our
international business opportunities and we plan to hire a general manager for
international commercial operations who will be based in Europe and report to
me. We also made good progress with our promising IRE program during the fourth
quarter. Our team is currently implementing clinical programs designed to gain
specific labeling for the treatment of prostate and pancreatic cancers in the
U.S. and generate clinical outcome data for Liver/HCC therapy in international
markets," concluded Mr. Keltjens.

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

o     The Company has determined that it will focus on three strategic clinical
      programs for the NanoKnife(TM) IRE system. The programs will focus on
      prostate, pancreatic and HCC/liver cancers. There has been good progress
      with pre-clinical work supporting FDA Investigational Device Exemptions
      and the first patient enrollment is expected before the end of calendar
      year 2009. To date, 66 NanoKnife procedures have been conducted worldwide
      in seven centers, including the first fully commercial IRE case at Banner
      Good Samaritan hospital in Phoenix.

o     AngioDynamics has released NanoKnife software version 2.0.7. Among other
      features of the software, version 2.0.7 offers a robust cardiac
      synchronization algorithm to avoid ventricular arrhythmia during
      irreversible electroporation near the heart, an occurrence which had been
      noted in a few early NanoKnife cases but not since this feature was
      implemented.

o     During the past seven weeks, AngioDynamics launched four new products:

      -     The Starburst(R) Xli-enhanced Semi-Flex electrode is the first
            radiofrequency ablation (RFA) device specifically designed to
            deliver a 7cm ablation of a tumor in a single placement during
            CT-aided procedures.

      -     The Starburst(R) XL is an RFA device with a convenient, pre-attached
            main cable designed to provide reproducible spherical ablations up
            to 5cm.

      -     The DuraMax(TM) hemodialysis catheter is AngioDynamics' latest
            evolution in the Company's market-leading stepped tip design that
            improves ease of use, dialysis efficiency and overall patient
            outcomes.

      -     The NeverTouch-FRS (fiber recognition system) makes NeverTouch(TM)
            fiber technology compatible with AngioDynamics' latest Delta Laser
            system, as well as lasers formerly manufactured by Diomed.

o     A Center of Excellence for Process Engineering & Technology has been
      established at the Company's Queensbury manufacturing operations. The goal
      of the Center is to drive stronger product designs plus manufacturing
      efficiencies resulting in improved supply chain performance including
      stable product supply and improved gross margins.

      Fiscal 2010 Guidance

The Company's outlook for fiscal 2010 is as follows:

      o     Net sales in the range of $209 million to $215 million, an increase
            of 7-10% over fiscal 2009 net sales

      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 $0.43 to $0.47, inclusive of a $0.24 EPS
            impact from IRE investments

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, the
Company has reported non-GAAP EBITDA, (income before interest, taxes,
depreciation and amortization) and non-GAAP EBITDA per share. Management uses
these measures in its internal analysis and review of operational performance.
Management believes that these measures provide investors with useful
information in comparing the Company's performance over different periods. By
using these non-GAAP measures, management believes that investors get a better
picture of the performance of the Company's underlying business. Management
encourages investors to review the Company's financial results prepared in
accordance with GAAP to understand the Company's performance taking into account
all relevant factors, including those that may only occur from time to time but
have a material impact on the Company's financial results. Please see the tables
that follow for a reconciliation of Operating Income to non-GAAP measures.
