    (B)(4). DURING PROCESSING OF THIS COMPLAINT, ATTEMPTS WERE MADE TO OBTAIN COMPLETE EVENT, PATIENT AND DEVICE INFORMATION. THE OTW TREK DILATATION CATHETERS ARE BEING FILED UNDER SEPARATE MEDWATCH MFR REPORTS. FACTORS THAT MAY CONTRIBUTE TO THE INABILITY TO RETRACT THE STENT DELIVERY SYSTEM OVER THE GUIDE WIRE AND CAUSE RESISTANCE BETWEEN THE DEVICES MAY INCLUDE, BUT NOT LIMITED TO, DEVICE PLACEMENT TECHNIQUE, GUIDING CATHETER SUPPORT, INNER DIAMETER OF GUIDE WIRE LUMEN, OUTER DIAMETER OF THE GUIDE WIRE, CONDITION OF THE GUIDE WIRE, BUILD UP OF BLOOD OR CONTRAST, OR DAMAGE TO THE CATHETER. TO ENSURE THIS IS NOT THE RESULT OF PRODUCT DEFICIENCY, ALL PRODUCTS ARE 100% VISUALLY INSPECTED FOR PROPER GUIDE WIRE MOVEMENT ON THE MANUFACTURING LINE. ADDITIONALLY, DURING LOT RELEASE TESTING, A SAMPLING OF UNITS IS DESTRUCTIVELY TESTED TO ENSURE PROPER GUIDE WIRE REVERSIBILITY. RETURN OF THE OTW MINI VISION SDS AND GUIDE WIRE MAY HAVE AIDED IN THE INVESTIGATION AND DETERMINATION OF CAUSE. A REVIEW OF THE PRODUCT MANUFACTURING RECORDS DID NOT REVEAL ANY NON-CONFORMING MATERIAL RECORDS ASSOCIATED WITH THIS LOT AND ALL LOT RELEASE TESTING MET MANUFACTURING CRITERIA. ADDITIONALLY, A QUERY OF THE COMPLAINT-HANDLING DATABASE WAS PERFORMED AND THERE HAS BEEN NO OTHER INCIDENTS REPORTED FOR DIFFICULTY REMOVING THE GUIDE WIRE FOR THIS LOT. THERE IS NO INDICATION OF A LOT SPECIFIC PRODUCT QUALITY DEFICIENCY.
