Cardima Meets with FDA Regarding Revelation Tx.

FREMONT, Calif. -- Cardima (Nasdaq Small Cap: CRDM) today announced that it met with the Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration (FDA) on June 18, 2004, in response to the FDA's encouragement for Cardima to meet with FDA representatives subsequent to the issuance of the FDA's letter stating that Cardima's REVELATION Tx Microcatheter system pre-market approval application (PMA) was not approvable.

As previously announced, the non-approvable letter was received by Cardima on May 28, 2004, and it informed Cardima that the FDA had determined that Cardima's REVELATION(R) Tx Microcatheter with NavAblator(R) Ablation System pre-market approval application (PMA) was not approvable based on applicable regulatory requirements. The letter indicated that the FDA believed that collecting additional data using a revised study design would be the least burdensome approach to demonstrate the device's safety and effectiveness.

At the meeting on June 18th, FDA reiterated its view, as stated in its non-approvable letter, that data from an additional study would be necessary to demonstrate the effectiveness of the REVELATION Tx for atrial fibrillation. The FDA representatives stated that the nature of the trial's primary goal, reduction in the number of AF episodes after ablation, would require a randomized clinical trial design. Representatives of Cardima and FDA exchanged views on how such a study would need to be designed and conducted.

Gabriel Vegh, CEO of Cardima said, "We continue to believe the REVELATION family of microcatheters has the potential to provide promising tools for the effective treatment of atrial fibrillation and ultimately provide a viable treatment alternative to the millions of individuals suffering from atrial fibrillation. We are disappointed, but not discouraged. This meeting provided a useful opportunity to exchange views with agency representatives in person, and at this time we are reviewing all options available to us."

Cardima is considering its alternatives in light of the views communicated by the FDA's representatives at the meeting. Cardima's goal remains to gain approval for the REVELATION microcatheter technology to treat atrial fibrillation by medical practitioners in the field of electrophysiology.

About Cardima

Cardima, Inc. has developed the REVELATION(R) Tx, REVELATION T-Flex and REVELATION Helix linear ablation microcatheters, the NAVIPORT deflectable guiding catheters, and the INTELLITEMP energy management system for the minimally invasive treatment of atrial fibrillation (AF). The REVELATION Helix was developed for the treatment of AF originating in the pulmonary veins of the heart. The REVELATION Tx, REVELATION T-Flex and REVELATION Helix systems and the INTELLITEMP have received CE Mark approval in Europe. The Company has also developed a Surgical Ablation System, which is expected to be used by cardiac surgeons to treat AF by ablating cardiac tissue during heart surgery using radio frequency (RF) energy. In February 2003, the Company announced that it had received FDA 510(k) clearance to market the Surgical Ablation System in the U.S.
