H10: manufacturing review: a manufacturing review was not required as this is the only complaint reported to date for this product and lot.Investigation summary: one ultrascore forced focus dilatation catheter with an unknown sheath was returned for evaluation.The catheter was noted to be stretched, and scoring wire was noted to be broken from the distal tip of the balloon.The distal tip was noted to be deformed.The unknown sheath that was returned was noted to be detached and deformed.No functional testing was performed due to the condition of the device.No evidence of balloon detachment was noted during the evaluation of the returned device.All the anomalies noted under microscopic observation.As a result, the investigation for the reported balloon detachment was unconfirmed because no balloon detachment was observed during the visual evaluation.The investigation for the reported difficulty removing the catheter from its sheath and the identified stretching of the catheter was confirmed as the returned catheter was noted to have stretch marks over the catheter shaft.The investigation was also confirmed for the identified scoring wire break, as these anomalies could be noted during the visual evaluation of the returned device.The investigation was also confirmed for identified distal tip deformation, as these anomalies could be noted during the visual evaluation of the returned device.A definitive root cause for the reported balloon detachment, reported difficulty removing the catheter from its sheath and the identified stretching of the catheter, identified scoring wire break and identified distal tip deformation could not be determined based upon the provided information.Labeling review: a review of product labeling documentation (e.G., procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.H10: b5, d4 (expiry date: 02/2024),.
