Definitions

  • Fig. 1 schematically illustrates a clot capture coil system according to the present invention incorporating an introducing catheter and a coil capture apparatus;
  • a coil capture system 2 includes a coil capture device 4 for capturing and removing a clot or thrombus in an anatomical lumen and a delivery catheter 6 for percutaneously delivering the capture coil device 4 to the clot region of the anatomical lumen.
  • Delivery catheter 6 comprises a catheter body 12 having an axial lumen 14 for receiving capture coil device 4 and a guide wire (not shown) .
  • Inner lumen 14 includes a capture coil/guide wire port 16 at its distal end and a proximal hub 18 at its proximal end.
  • the hub 18 includes a capture coil/guide wire port 20 and a fluid delivery port 22 which both communicate with axial lumen 14.
