Migraine: Can Devices Spell Relief
Executive Summary
As many as half of severe migraine sufferers do not achieve adequate relief with prescription drug therapy, and many of these patients may be candidates for emerging device treatments for migraine. Sales of migraine drugs in the U.S. total more than $2 billion per year, but some analysts believe that the potential market for device-based treatment may be even larger. The question at the moment is whether the devices in development can produce the kind of results that migraine patients are looking for. Clinical trials are currently underway on a number of fronts, and based on early data, the answer looks promising.

PFO Closure: Challenges and Opportunities
Over the past several years, device manufacturers have introduced a number of PFO closure devices in Europe, but conducting randomized trials to gain US market approval has proven to be a much more difficult endeavor. Companies have experienced numerous delays and setbacks in both their stroke and migraine programs. The good news: setbacks for some could also boost randomized migraine studies still ongoing by other competitors in this field.
