Figure 4. a–c.

Techniques related to the use of a biopsy forceps. Short black arrow indicates the angiosheath; long black arrow indicates the fractured catheter; and the dashed arrow indicates the biopsy forceps. In panel (a), the guidewire is threaded through catheter and forceps opened at the distal end of the fractured catheter. Panel (b) shows directly grasping the fracture end of the catheter. In panel (c), the guidewire is threaded through catheter and opened within the lumen, acting as an anchor while steadily pulling out the fragment.
