Abstract

An embolism treatment device includes an elongated core wire having a coil tip coupled to the distal end of the core wire and a cage assembly substantially coaxial to the core wire, having a first deployment shape and a second expanded shape. The core wire is freely moveable axially through the cage assembly. The device additionally includes an inner coil surrounding the core wire within the cage assembly and an actuator element, having a first position and a second position, located proximally to the cage assembly, wherein when the actuator element is in the first position, the cage assembly is in the first deployment shape and when the actuator element is in the second position, the cage assembly is in the second expanded shape.
