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 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 28,000 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. The prevalence of migraines in the United States is about 10%. Of the 28 million migraine sufferers in America, those who experience aura and have a PFO may represent a three million patient subset.
