A clot retrieval device is disclosed to remove clot from a blood vessel. The device can include a collapsed configuration and an expanded configuration. The device can include an inner expandable body with a framework of struts. The device can include an outer expandable body with a framework of struts that at least partially radially surrounding the inner expandable body. A distal portion of the outer expandable body can extend in the deployed configuration towards the outer expandable body to a greater extent than the inner expandable body, closed cells of the distal portion distally tapering and being smaller than cells proximal thereof in the outer expandable body. The plurality of closed cells of the distal portion can include a pair of axially aligned smaller diamond shaped cells formed by struts of the distal portion and positioned along upper and lower regions of the distal portion.

Clot retrieval device for removing clot from a blood vessel

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.
