FDA Dispute Resolution Panel Recommends to Not Approve REVELATION® Tx Microcatheter System

FREMONT, CA -- (MARKET WIRE) -- April 20, 2007 -- Cardima, Inc. (OTCBB: CRDM), a medical device company focused on the treatment of atrial fibrillation, announced today that the FDA's Medical Device Dispute Resolution Panel, which met on April 19, 2007, recommended to not approve the Company's REVELATION® Tx Microcatheter System. Even though the Panel commented favorably on the need for this type of device, the Panel felt that efficacy data was not sufficiently clear and supportive for approval.

The REVELATION® Tx system is a minimally invasive, single-use, microcatheter-based product designed to provide easy access to arrhythmia-causing tissue, creating linear lesions or restricted pathways, and restoring normal sinus rhythm to the heart using radiofrequency (RF) energy.

Gabe Vegh, Chief Executive Officer of Cardima, said, "I am disappointed that the Panel voted against the approval of the REVELATION® Tx. Cardima will consider its options regarding this decision in the US. The Company will continue to market its next generation ablation EP systems, which include the REVELATION® T-Flex and the INTELLITEMP®, in the European Union and the rest of the world where it is licensed to promote and sell these products. Also Cardima will continue to search for marketing partners for its US-approved Surgical Ablation System (SAS) and in the markets outside of the US where it is licensed to promote and sell the product. In addition, the Company will continue to promote its Diagnostic System which is approved in the US and the rest of the world."
