[EN] Method and apparatus for fragmentation of a lung embolus. The apparatus includes a catheter that is introduced over a guide wire to the site of the lung embolism in the vascular system of a patient. When the guide wire is withdrawn from the distal end segment of the catheter, the distal end segment bends back proximally. An opening in the bend of the catheter is in line with the central axis of the catheter when the distal end segment is in a curved configuration. The guide wire is then advanced to extend distally from the catheter opening past the embolism and stabilize the longitudinal position of the catheter in the blood vessel. The apparatus also includes a thread for pulling the bent distal end segment into a generally oval-shaped loop condition and stabilizing the loop about the embolism. The looped catheter is then rotated and moved longitudinally back and forth for mechanically destroying the embolism. To return the catheter to a straight condition, the rigid guide wire is withdrawn from the catheter, and a guide wire with a resilient J-tip is advanced to the distal end segment of the catheter. The J-tip guide wire follows the catheter past the catheter opening, thereby straightening the catheter for removal from the body. The apparatus optionally includes a handle or motor positioned at the proximal end of the apparatus. |
