Researchers who are developing the treatment, which makes use of special plastics called polyurethane-based shape memory polymer foams （SMPs）. Its effectiveness in helping to the heal aneurysms. Typically, treatment of aneurysms involves either surgically clipping the aneurysm or implanting platinum coils to reduce pressure on the vessel walls so that healing can occur before the aneurysm ruptures. In addition to sometimes causing inflammation that can inhibit healing, these coils can compact over time and cause subsequent rupture or re-rupture or lead to the formation of aneurysms adjacent to the original aneurysm.
