Abstract
An expandable frame for an embolic filtering device used to capture embolic debris in a body lumen. The expandable frame also includes a filtering element. A nickel-titanium alloy is used to form the frame. Due to limited heat treatment, the frame exhibits linear pseudoelasticity when positioned inside the body lumen. The nickel-titanium alloy includes a ternary element such as iridium, platinum, gold, rhenium, tungsten, palladium, rhodium, tantalum, silver, ruthenium, or hafnium so that the frame is also radiopaque.
