          NITINOL MEDICAL TECHNOLOGIES ANNOUNCES SHAREHOLDER APPROVAL
          -----------------------------------------------------------
                      OF NAME CHANGE TO NMT MEDICAL, INC,
                      -----------------------------------

Shareholders Also Ratify Election of All Seven Members of the Board of Directors

Boston, MA, June 3, 1999 - Nitinol Medical Technologies, Inc., (d/b/a "NMT
Medical") (Nasdaq/NMS;NMTI) today announced that at its Annual Meeting held this
morning, shareholders approved the official change in the Company's name to NMT
Medical, Inc. Shares of NMT Medical will continue to trade on the Nasdaq
National Market under the symbol NMTI.

The Company also announced that its shareholders had ratified the election of
all seven members of the Board of Directors.

Thomas M. Tully, President and Chief Executive Officer of NMT Medical said that
the Company decided to change its name in order to better reflect the
diversified range of products it now offers. The Company was founded in 1986 to
design, develop and commercialize medical devices specifically engineered using
thermal shape-memory nitinol, a nickel-titanium alloy. The Company's first two
FDA-approved products, the Simon Nitinol Vena Cava Filter(R) and the
Symphony(TM) stent, were both among the first medical devices to be fabricated
from thermal shape-memory nitinol.

In recent years, however, NMT Medical has expanded its product portfolio through
the acquisition of the CardioSEAL(R) Septal Occluder (a cardiac implant
designed to close holes in the heart), NMT Neurosciences (a division of NMT
Medical which provides a number of market leading products for the neurosurgery
market), and a minority investment in Image Technologies Corporation ( a
privately held company which is developing products aimed at the endoscopic
market).
