Disclosed is a clot and foreign body removal system, including a catheter with at least one lumen. Located within the catheter is a clot capture wire that is connected to a hub at the proximal end. In one embodiment, the clot capture wire includes a coil made out of an elastic or superelastic material, preferably nitinol. The elasticity or superelasticity of the coil allows it to be deformed within the catheter and to then reform its original coil configuration when the coil is moved outside of the catheter lumen. In another embodiment the coil is a biphasic, shape memory coil, which changes shape upon heating, energy application, or passing an electric current. Once the coil configuration has been established, the coil can be used to ensnare and corkscrew a clot or blockage in a vessel. A clot is extracted from the vessel by moving the clot capture coil and catheter proximally until the clot can be removed completely or released into a different vessel that does not perfuse a critical organ. Foreign bodies are similarly captured by deploying the coil distal to the foreign body and moving the clot capture coil proximally until the foreign body is trapped within the coil. By removing the device from the body, the foreign material is also removed.
