ScienceDaily () -- Interventional cardiologists used magnetic particles to accelerate the process of healing after the placement of a stent. To do this, they extract cells from the interior of a patient's blood vessels, cultivate them, and insert iron-based paramagnetic particles into the cells. When the cells are reintroduced to the blood, this attracts them to the magnetic coating on the stent, creating a film of living cells that promotes tissue healing and ultimately reduces the risk of blood clot formation.
