Item 2.01. Completion of Acquisition or Disposition of Assets.

On January 6, 2006, ev3 Inc. ( “ev3”) announced that it had completed its previously disclosed acquisition of the outstanding shares of Micro Therapeutics, Inc. (“MTI”) that it did not already own through the merger (the “Merger”) of Micro Investment, LLC, a wholly owned subsidiary of ev3 (“MII”), with and into MTI, effective January 6, 2006, with MTI continuing as the surviving corporation and a wholly owned subsidiary of ev3. As the majority stockholder of MTI, ev3 previously executed a written consent approving the Merger, which was the only stockholder approval necessary or required to complete the Merger under applicable law or the Agreement and Plan of Merger (the “Merger Agreement”), dated as of November 14, 2005, by and among ev3, MII and MTI. Pursuant to the Merger Agreement, and as a result of the Merger, each share of common stock of MTI outstanding at the effective time of the Merger was automatically converted into the right to receive 0.476289 of a share of ev3 common stock (the “Exchange Ratio”) and cash in lieu of any fractional share of ev3 common stock. In addition, each outstanding option to purchase shares of MTI common stock was converted into an option to purchase shares of ev3 common stock on the same terms and conditions (including vesting) as were applicable under such MTI option and the exercise price and number of shares for which each such option is (or will become) exercisable was adjusted based on the Exchange Ratio.

In connection with the Merger, ev3 will issue approximately 7.0 million shares of its common stock to holders of outstanding shares of MTI common stock. The shares of ev3 common stock to be issued in accordance with the Merger Agreement were registered under the Securities Act of 1933, as amended, pursuant to ev3’s Registration Statement on Form S-4 (File No. 333-129956) (the “Registration Statement”) initially filed with the Securities and Exchange Commission (the “SEC”) on November 23, 2005 and declared effective on December 7, 2005. The information statement/prospectus of ev3 and MTI, dated December 6, 2005, that forms a part of the Registration Statement contains additional information about the Merger.

The MTI common stock was registered pursuant to Section 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and listed on the NASDAQ National Market under the symbol “MTIX.” MTI has filed a Form 15 with the SEC to terminate registration of the MTI common stock under the Exchange Act and the MTI common stock was delisted from trading as of the close of the market on January 6, 2006.

On January 6, 2006, ev3 issued a press release announcing the completion of the Merger. A copy of the press release is attached hereto as Exhibit 99.1. The foregoing description of the Merger Agreement and the transactions contemplated thereby, including the Merger, is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and is incorporated by reference herein.
