• Q3 2006 Revenue Growth of 10%
• Company Reaffirms Full Year 2006 Revenue Guidance

DANVERS, Mass. (February 2, 2006)—ABIOMED, Inc. (NASDAQ: ABMD) today released financial results for its third fiscal quarter of 2006 that ended on December 31, 2005. Revenue for the third quarter of fiscal 2006 grew 10% to $10.5 million compared to the same period of fiscal 2005.

Recent financial and operating highlights include:

• Revenue increased 10% on a consolidated basis to $10.5 million over the same quarter of the prior year. Total disposable VADs sold this quarter again exceeded 500 units.
• Greater than 50% of third quarter fiscal 2006 revenue was derived from new products and programs launched since the beginning of fiscal 2004.
• More customers participated in the AB5000™ Console Rental Program this quarter. ABIOMED did not offer the rental program in the third fiscal quarter of 2005. During the third fiscal quarter of 2006, approximately 40% of the second quarter rentals converted to sales.
• The Company incurred a loss of $0.17 per share, or $4.4 million, compared to a loss of $0.01 per share, or approximately $0.2 million, in the third quarter of fiscal 2005. This was driven primarily by planned increases in R&D and SG&A of $4.5 million to generate growth and promote recovery awareness. Approximately 70% of the Company's R&D investments are focused around its VAD recovery platforms, its IMPELLA® technologies and other new products.
• In order to continue to expand business in the United States and abroad, ABIOMED hired top sales talent from within the industry. ABIOMED added two new sales representatives in the U.S. This brings ABIOMED's total sales and clinical team to 30 in the U.S. and 10 in Europe.
• In the U.S., the new AB5000 Console is now in 39 of the 119 transplant centers or 33%, and 57 of the 867 open heart centers or 7%. This quarter 1 in 4 transplant centers in the U.S. ordered at least 1 AB5000 Ventricle.
• During the quarter, the Company completed productivity initiatives that are expected to generate approximately $1 million of annual cost savings to reinvest in the Company's global distribution.

"We have made encouraging progress establishing our core business of disposable VADs with strong gross margins. ABIOMED's momentum will grow with our expanded distribution and as we add new breakthrough technology to our product portfolio for heart recovery. Our momentum through our fiscal third quarter provides us with the confidence to reaffirm our full year 2006 revenue guidance of the low $40 millions," said Michael R. Minogue, Chairman, CEO and President of ABIOMED.

ABIOMED is currently the only company with FDA labeling on ventricular assist devices for all potentially recoverable indications. To date, more than 8,000 patients worldwide have been supported with these devices. Patients who have recovered included those suffering from cardiogenic shock resulting from myocardial infarction, myocarditis, postpartum cardiomyopathy, ventricular septal defect, refractory arrhythmias, failed heart transplants, right ventricular assistance with implantable LVAD (Left Ventricular Assist Device), and post-cardiotomy cardiogenic shock (PCCS). ABIOMED's devices encourage recovery and are easier to implant, utilizing cannula inserted through a small incision, rather than more traumatic bridge-to-transplant devices that core the ventricles and require heart-lung machines for implantation. The ABIOMED® AB5000™ System also allows patients to walk with the support of the console, which helps recovery.
