H10: manufacturing review: a manufacturing review was not requested as the lot number reported is unknown.Investigation summary: one ultrascore pta dilatation catheter with an unknown guidewire that appeared exposed from both guidewire luer and distal end of the balloon has returned for evaluation.On the visual evaluation of the device, it appeared to be bloody and the sample was returned with.014 guidewire stuck inside of the device, no anomalies to the luer or y-body.The balloon appeared deflated and corewires were present.No other specific anomalies were noted.On the functional evaluation of the device, attempted to remove the guidewire but was unsuccessful.Upon microscopic evaluation, catheter was cut and noted dried blood within the inner guidewire lumen and on the guidewire itself.No further testing was performed.Therefore, the investigation is confirmed for the reported difficult to remove as an attempt was made to remove the guidewire but was unsuccessful.The investigation remains inconclusive for the reported difficult to advance and device-device incompatibility as no other functional testing was performed as the dried blood residue was noted in the inner guidewire lumen.A definitive root cause for the alleged difficult to advance, device-device incompatibility, difficult to remove 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.H11: section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant/reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.H3 other text: see h10.
