Manufacturing review: the device history records have been reviewed and this lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Investigation summary: one powerport mri isp implantable port, one flushing connector and a cath-lock loaded to a groshong catheter, one vein pick, one cath-lock, one right-angle non-coring needle, one straight non-coring needle, one vessel dilator, one groshong catheter segment and one 8.0fr partially peeled peel-apart sheath and vessel dilator were returned for evaluation.Gross visual, microscopic visual, tactile evaluation and functional testing were performed.However, the investigation is inconclusive for the reported difficult to insert issue as the exact circumstances at the time of the reported event cannot be verified and the sample evaluation results indicating no difficulty under laboratory conditions are not by themselves sufficient to confirm this event occurred under clinical conditions.The investigation is confirmed for the reported sheath deformation and identified fracture issues as the 8.0fr sheath was noted to have a complete diagonal break and was noted to be bent.Further, a kink was noted on the sheath and the vessel dilator was noted to be bent.Under microscopic observation, the edges of the complete diagonal break on the peel-apart sheath was noted to be uneven.A definitive root cause could not be determined based on the available 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.(expiration date: 04/2024).
