27th Annual J.P. Morgan Healthcare Conference January 12, 2009

Forward-Looking Statements Statements contained in this presentation that relate to future, not past, events are forward-looking statements under the Private Securities Litigation Reform Act of 1995. Forward-looking statements often can be identified by words such as "expect," "anticipate," "estimates," "intend," "will," "may," "believe," "could," "continue," "future," "outlook," "guidance," the negative of these words or other words of similar meaning and the use of future dates. Forward-looking statements by their nature address matters that are, to different degrees, uncertain. Uncertainties and risks may cause ev3's actual results to be materially different than those expressed in or implied by ev3's forward-looking statements. For ev3, particular uncertainties and risks include, among others, ev3's future operating results and financial performance, fluctuations in foreign currency exchange rates, ev3's ability to implement, fund and achieve sustainable cost savings measures that will better align its operating expenses with its anticipated net sales levels and reallocate resources to better support growth initiatives, the effect of the current global economic crisis, the timing of regulatory approvals and introduction of new products, market acceptance of new products, success of clinical testing, availability of third party reimbursement, impact of competitive products and pricing and changes in the regulatory environment. More detailed information on these and additional factors that could affect ev3's actual results are described in ev3's filings with the Securities and Exchange Commission, including its most recent annual report on Form 10-K and subsequent quarterly reports on Form 10-Q. Except as required by law, ev3 undertakes no obligation to update publicly its forward-looking statements.

Use of Non-GAAP Financial Measures ev3 uses certain non-GAAP financial measures in this presentation, including "non- GAAP adjusted net income (loss)," "non-GAAP adjusted net earnings (loss) per share," and "peripheral vascular net sales, excluding atherectomy." ev3 uses non- GAAP financial measures as supplemental measures of performance and believes these measures provide useful information to investors in evaluating our operations, period over period. However, non-GAAP financial measures have limitations as analytical tools, and should not be considered in isolation or as a substitute for ev3's financial results prepared in accordance with GAAP. In addition, investors should note that any non-GAAP financial measures ev3 uses may not be the same non- GAAP financial measures, and may not be calculated in the same manner, as that of other companies. We have posted a reconciliation of our non-GAAP financial measures to the most directly comparable GAAP financial measures on our website at www.ev3.net.
