Abstract
An embolectomy device includes a clot engaging structure comprising a plurality of interconnected struts forming an open cell structure, and further includes an attachment structure configured to advance and retract the clot engaging structure out of, and back into, respectively, the open distal end of a delivery catheter, the attachment structure comprising an elongated support member attached to one or more struts of the clot engaging structure only at locations on each of the respective one or more struts that are distal of a proximal end of the clot engaging structure.

An embolectomy device, comprising:
- a delivery catheter having a lumen in communication with an open distal end;
- a clot engaging structure comprising a plurality of interconnected struts forming an open cell structure, the open cell structure comprising a plurality of diagonally disposed cell structures, the clot engaging structure having a proximal end portion that terminates at a proximal end;
- and
- an attachment structure configured to advance and retract the clot engaging structure out of, and back into, respectively, the distal end opening of the delivery catheter within a targeted blood vessel, the attachment structure comprising an elongated support member attached to one or more struts of the clot engaging structure, the elongated support member having a distal end portion that terminates at a distal end,
- wherein the distal end of the elongated support member is attached to one or more struts of the clot engaging structure only at locations on each of the respective one or more struts that are distal of the proximal end of the clot engaging structure, so that withdrawal forces are exerted to the locations distal of the proximal end of the clot engaging structure when retracted.
