Abstract
A clot retrieval device including a self-expandable member having a proximal end portion and a main body portion. The self-expandable member is expandable from a first delivery position to a second placement position. In the first delivery position the expandable member has a first overall diameter In one implementation the cell structures that form the self-expandable member have dimensional and material characteristics that result in about a −1.0N to about a −1.7N overall reduction in radial force along the length of the expandable member per millimeter of expansion during about an initial 0.50 mm diametric range of expansion from the first overall diameter and that results in about a −0.10N to about a −0.35N overall reduction in radial force along the length of the expandable member per millimeter of expansion during subsequent diametric ranges of expansion.
