As reported, the tip of the 0.018" 300cm straight (st) sv short peripheral steerable guidewire (pgw) broke in patient.The wire was successfully retrieved.There was no reported patient injury.A v-18 wire was used instead of sv-5.The target lesion was mildly stenosed.The device was stored per labelling and opened in sterile field.The products were stored, handled and prepped according to the instructions for use (ifu).The wire were removed from the sharp end to the rubber stopper and pushed wire through wire house.The wires were not kinked or damaged in any way prior to insertion into the patient.The wire was advanced within a 4 fr non-tapered angle glide catheter in the right lower pulmonary vein and anchored within a small branch.The wire was advanced smoothly without any force.The wire tip was curved within the small vessel as usual.However, there was significant resistance when attempting to remove the wire back in to the catheter.We needed to remove the wire by pulling back the catheter almost to the pulmonary vein ostium and slowly pulling wire back with ¿small shaking motion¿ until the wire was free.The sv wire was only used for one lesion, however, the wire was in and out of patient and in and out of catheters.Used with 4x2 competitor's balloon.Wire was exchanged multiple times.The device is expected to be returned for analysis.No other information was provided.
