A method of removing clot from a vessel, including delivering a clot retrieval device across the clot, wherein the clot retrieval device includes an inner body having a collapsed delivery configuration and an expanded deployed configuration; and an outer body extending along a longitudinal axis and at least partially overlying the inner body. The outer body includes a first scaffolding section, a second scaffolding section hingedly connected distal of the first scaffolding section; the first and second scaffolding sections of the outer body being 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 between the inner and outer bodies. The method also includes expanding the clot retrieval device; and urging, by the expanding of the first and second scaffolding sections, at least a portion of the clot therebetween.

Clot retrieval device for removing occlusive clot from a blood vessel

A device for removing a clot from a blood vessel. The device can have a collapsed delivery configuration and an expanded deployed configuration. The device can have a shaft. An outer expandable body can be included that is radially expandable from a first radially expanded state to a second radially expanded state in the deployed configuration. An inner body can be included, wherein the outer expandable body and the inner body are fixedly coupled to a distal region of the shaft, the outer expandable body radially surrounding at least a portion of the inner body in the second radially expanded state. A capture net can be coupled to a distal portion of the inner body and including a proximal mouth.

Clot retrieval device for removing a clot from a blood vessel

Method for using a clot retrieval device for treating a clot in a blood vessel for use in the treatment of ischemic stroke to reperfuse an obstructed vessel.

Systems and methods of restoring perfusion to a vessel

A clot retrieval device () for removing clot from a blood vessel comprises an inner elongate body () and an outer elongate body () at least partially overlying the inner elongate body (). The device also comprises an elongate member or shaft () having a proximal end which extends exterior of a patient so that a user can retrieve the stent-basket device and captured clot by retracting the shaft (). The outer elongate body () and the inner elongate body () are connected to the distal end of the shaft () and are expandable relative to the shaft () from a collapsed delivery configuration to an expanded deployed configuration. The outer elongate body () is expandable relative to the inner elongate body () to a radial extent which is greater than the radial extent of the inner body () in the deployed configuration.

The outer elongate body () is expandable relative to the inner elongate body () to a radial extent which is greater than the radial extent of the inner body () in the deployed configuration. The stent-basket construction of the device creates a reception space () between the inner () and outer () to receive the target clot. The outer body () is configured to allow as much as possible of the clot to migrate through it into the internal reception space (). Housing the clot in this reception space rather than pinning it to the wall of the vessel means that the clot is under less compression and can thus be retracted at a lower force. The inner elongate body () and a distal capture net () protect the distal vascular bed from embolization.
