Boston Scientific's stent approved for peripheral artery disease

The Innova Vascular Self-Expanding stent by Boston Scientific prevents the blocking of arteries in the leg

The stent was approved by the FDA in the United States four years after the device was recalled outside the country due to partial or no deployments.

The device consists of a self-expanding metal stent with an advanced delivery system which helps in accurate deployment.

The Innova Vascular Self-Expanding stent is implanted into the arteries in the legs to prevent peripheral artery disease, which can lead to painful ulcers and infections, or even amputation of the toes or feet.

The company recalled over 500 devices in 2011 as partial deployments could result in vessel wall injury, increased procedure time or an emergency surgery to remove it.
