Item 5. –Other Events

On October 27, 2003, Micro Therapeutics, Inc. (“MTI”) issued a press release announcing that a Dutch court has ruled that MTI’s Sapphire embolic coils infringe three patents that are held by the University of California (“UC”) and its licensee, Boston Scientific Corporation (“BSC”).

MTI is initiating actions to preserve its ability to sell and market its embolic coils within the EU, prevent possible injunctive actions, and file for appeal. Revenue from MTI’s Sapphire embolic coils in Europe represent between 11% and 13% of total corporate revenues. The Dutch court decision was in conjunction with a legal action initiated by MTI in September 2002 to assert the invalidity of four patents held by the UC and BSC as well as MTI’s non-infringement of such patents. The court ruled that one of the UC/BSC patents, which covers a dual marker band coil delivery catheter, is invalid.

The full text of the press release is set forth in Exhibit 99.1 attached hereto and is incorporated herein by reference.
