Patent attributes
A clot retrieval device includes an inner expandable member and an outer expandable member, each formed from respective strut frameworks such that the outer expandable member has larger cell openings than the inner expandable member. The outer expandable member can have multiple discontinuous body segments spaced apart in relation to a longitudinal axis of the device. Adjacent discontinuous body segments can be joined by a pair of tapered connecting arms that are able to bend with a small radius of curvature compared to the body segments. Some or all of the body segments can include radiopaque markers positioned to illustrate a circumference of the respective body segment and slightly staggered in relation to a longitudinal axis of the device such that the markers nest when the device is collapsed for delivery.
