Abstract
A clot retrieval device for removing occlusive clot from a blood vessel. The device comprises an inner elongate body having a collapsed delivery configuration and an expanded deployed configuration. An outer elongate body is at least partially overlying the inner elongate body. The outer elongate body is expandable to a radial extent which is greater than the radial extent of the inner body in the deployed configuration to define a clot reception space. The outer elongate body has a plurality of clot receiving openings and a plurality of clot engaging regions. The clot engaging regions are adapted, on engagement with clot, to urge clot towards the clot receiving openings and into the reception space between the outer elongate body and the inner elongate body, wherein the radial force profile of the device varies along the length of the device.
