About NMT Medical, Inc.

NMT Medical is an advanced medical technology company that designs, develops,
manufactures and markets proprietary implant technologies that allow
interventional cardiologists to treat structural heart disease through minimally
invasive, catheter-based procedures. NMT Medical is currently investigating the
potential connection between a common heart defect that allows a right-to-left
shunt or flow of blood through a defect like a patent foramen ovale (PFO) and
brain attacks such as embolic stroke, transient ischemic attacks (TIAs) and
migraine headaches. A common right-to-left shunt can allow venous blood,
unfiltered and unmanaged by the lungs, to enter the arterial circulation of the
brain, possibly triggering a cerebral event or brain attack. More than 30,000
PFOs have been treated globally with NMT's minimally invasive, catheter-based
implant technology.

Stroke is the third leading cause of death in the United States and the leading
cause of disability in adults. Each year, 750,000 Americans suffer a new or
recurrent stroke and an additional 500,000 Americans experience a TIA.
