Manufacturing review: the device history records have been reviewed with special attention to the raw materials, subassemblies, manufacturing process, and quality control testing.This lot met all release criteria.Investigation summary: one crosser 14s catheter was returned for evaluation.The crosser catheter was returned inserted inside a sidekick catheter.The device was placed in x-ray and no breaks in the corewire or distal tip were identified.The tip of the sidekick is buckled indicating retraction issues.Therefore, the investigation is confirmed for retraction issue.The investigation is unconfirmed for tip detachment as the device was returned with the distal tip attached with no identified breaks.Per the evaluation results, the catheter was in specification, so it is unlikely that the shaft diameter was too large for the outer catheter.Based upon the available information, the definitive root cause is unknown.Labeling review: the review of the ifu (instructions for use), indications, warnings, precautions, cautions, possible complications, and contraindications showed that the product labeling is adequate.
