Retrieval of the detached tip of the Caravel™ microcatheter. (A) Fluoroscopy revealed an abnormal presence in the severe stenosis in the proximal part of the left circumflex artery (LCX) (red arrow). (B) After crossing the lesion with another guidewire (SION blue™), a guide-extension catheter (GuideLiner™) was inserted over two SION blue™ guidewires to the proximal site of the LCX. Subsequently, a small semi-compliant balloon (TREKTM 2.0 × 12 mm) was advanced over the second SION blue™ guidewire to the more distal site of the detached tip of the Caravel™ microcatheter (white arrow: GuideLiner™; yellow arrow: TREK™). (C) The GuideLiner™ was advanced using the anchor balloon technique. (D) The detached tip was completely covered by the GuideLiner™. (E) TREK™ was inflated to wedge the detached tip in the GuideLiner™. (F) All the devices were retrieved together (blue arrow).
