Patent ID: 8486104

Claim:
An embolism treatment device, comprising: an elongated core wire having a proximal section, a distal section, and a distal coil tip; a proximal cage assembly rotatably disposed on the distal section of the elongated core wire; a distal cage assembly rotatably disposed on the distal section of the elongated core wire distal the proximal cage assembly; a separation member disposed between the proximal cage assembly and the distal cage assembly; and an actuator element located proximal of the proximal cage assembly, the actuator element axially movable along the elongated core wire such that when the actuator element is in a first position, the proximal and distal cage assemblies are each in a collapsed configuration, and when the actuator element is in a second position, the proximal and distal cage assemblies are each in an expanded configuration; wherein the proximal cage assembly and the distal cage assembly are each self-collapsing.
