Abstract
A basket for an embolic protection filtering device to be deployed within a body lumen for capturing embolic debris is disclosed. In one embodiment, a strut pattern forming the basket includes V-shaped struts having an internal radius at the apex with a kerf on each strut arm beginning at the radius and extending toward an opposite end of the strut. The apex may have a bulbous shape. In another embodiment, the strut arms of the basket include undulations. Also, the apices may be situated so that one apex is longitudinally staggered from an adjacent apex. The combination of features enables the basket to be crimped to a small profile while distributing stress away from the apices of the V's in the strut pattern.
