Mechanical clot treatment device

1. An embolism treatment device comprising:

an elongated core wire having a distal end and a proximal end;

a cage assembly including a proximal cage connected to a distal cage, the cage assembly having a distal end, a proximal end, a first deployment shape wherein both the proximal cage and the distal cage are in a deployment configuration, and a second expanded shape wherein both the proximal cage and the distal cage are in an expanded configuration, wherein the second expanded shape is different from the first deployment shape and wherein the cage assembly is substantially coaxial to the elongated core wire;

a tubular member coupled to the distal end of the cage assembly, wherein the tubular member surrounds a distal portion of the core wire; and

an actuator element, having a first position and a second position, located proximally to the cage assembly and substantially coaxial about the core wire, 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;

wherein the core wire is freely moveable axially through the cage assembly;

wherein the proximal cage and the distal cage are separated by a separation member.

2. The embolism treatment device in claim 1 , wherein the tubular member is a bushing.

3. The embolism treatment device in claim 1 , wherein the tubular member is a thermoplastic.

4. The embolism treatment device in claim 1 , further comprising an inner coil surrounding the elongated core wire within the cage assembly.

5. The embolism treatment device in claim 4 , wherein the inner coil is a marker coil.

6. The embolism treatment device of claim 1 , wherein the distal cage includes a plurality of petal shaped wires.

7. The embolism treatment device of claim 6 , wherein the plurality of petal shaped wires has a distal rake.

8. An embolism treatment device comprising:

an elongated core wire having a distal end and a proximal end;

a cage assembly including a proximal cage connected to a distal cage, the cage assembly having a distal end, a proximal end, a first deployment shape, and a second expanded shape wherein both the proximal cage and the distal cage are in an expanded configuration, wherein the second expanded shape is different from the first deployment shape and wherein the cage assembly is substantially coaxial to the elongated core wire;

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 and substantially coaxial about the core wire, 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;

wherein the proximal cage and the distal care are separated by a separation member.
