It was reported during a planned diagnostic coronary procedure, the manufacturer¿s device could not cross the lesion in the lad [left anterior descending artery].The device was removed and the tip was reshaped.The physician attempted to cross the lesion again but could not.The device went into a small vessel near the target lesion and was trapped.The device could not be removed, therefore, the physician exchanged the diagnostic catheter with a guiding catheter.A goose neck snare was inserted into the guiding catheter and successfully retrieved the manufacturer¿s device.The distal portion was observed to be stretched.This adverse event is being submitted because additional intervention was required to retrieve the manufacturer¿s device.There is a potential for harm if the malfunction were to recur.
