Abstract
An intravascular flow modifier (IFM) for use in a vessel has an outer layer formed of a strand configured as a longitudinally oriented coil of adjacent helical loops extending between a first end and a second end of the outer layer. The outer layer is secured in the vessel by at least some of the helical loops pressing against a portion of the interior surface of the vessel. The IFM also has an inner layer formed of a strand configured as a longitudinally oriented coil of adjacent helical loops extending between a first end and a second end of the inner layer. At least a portion of the outer layer surrounds at least a portion of the inner layer so that at least some of the loops of the outer layer overlap and contact at least some of the loops of the inner layer. An assembly and method for deploying are also disclosed.
