An elongate embolectomy device biased to expand from a radially constrained configuration to a radially expanded configuration when released from a delivery catheter within a blood vessel , the embolectomy device comprising: a first elongate spine member extending along a longitudinal axis of the embolectomy device ; a second elongate spine member extending along the longitudinal axis of the embolectomy device , substantially parallel with the first elongate spine member ; a first plurality of clot engaging structures , each clot engaging structure of the first plurality having a first end attached to the first elongate spine member and a second end attached to the second elongate spine member ; and a second plurality of clot engaging structures , each clot engaging structure of the second plurality having a first end attached to the first elongate spine member at a location in which the first end of a corresponding clot engaging structure of the first plurality is attached to the first elongate spine member , and a second end attached to the second elongate spine member at a location in which the second end of the corresponding clot engaging structure of the first plurality is attached to the second elongate spine member , wherein the respective clot engaging structures are resilient and configured such that, when the embolectomy device is unsheathed within in a blood vessel alongside a clot , the clot engaging structures of one of the first and second plurality contact and compress against a wall of the blood vessel to provide a biasing force to facilitate engagement of the clot engaging structures of the other one of the first and second plurality with the clot , characterized in that each of the clot engaging structures comprises respective curved portions that extend from the first elongate spine member to a middle portion of the clot engaging structure, and from the middle portion to the second elongate spine member , wherein the respective middle portions of the clot engaging structures have a chevron/furcula-like configuration. a first elongate spine member extending along a longitudinal axis of the embolectomy device ; a second elongate spine member extending along the longitudinal axis of the embolectomy device , substantially parallel with the first elongate spine member ; a first plurality of clot engaging structures , each clot engaging structure of the first plurality having a first end attached to the first elongate spine member and a second end attached to the second elongate spine member ; and a second plurality of clot engaging structures , each clot engaging structure of the second plurality having a first end attached to the first elongate spine member at a location in which the first end of a corresponding clot engaging structure of the first plurality is attached to the first elongate spine member , and a second end attached to the second elongate spine member at a location in which the second end of the corresponding clot engaging structure of the first plurality is attached to the second elongate spine member , wherein the respective clot engaging structures are resilient and configured such that, when the embolectomy device is unsheathed within in a blood vessel alongside a clot , the clot engaging structures of one of the first and second plurality contact and compress against a wall of the blood vessel to provide a biasing force to facilitate engagement of the clot engaging structures of the other one of the first and second plurality with the clot , characterized in that each of the clot engaging structures comprises respective curved portions that extend from the first elongate spine member to a middle portion of the clot engaging structure, and from the middle portion to the second elongate spine member , wherein the respective middle portions of the clot engaging structures have a chevron/furcula-like configuration. <EOS>
