(b)(4).Device evaluated by mfr: the device was returned for analysis.There was a bent pin in the connector.The od (outer diameter) of the insulation at the proximal end of the tip was larger than the od of the tip itself.There were three gaps in the adhesive between the tip and the catheter shaft insulation, seen at 12.5x magnification.There was a crease in the insulation at each hole in the adhesive.The creases are discolored (white) and approximately 1mm long.This device was a 7fr device.The shaft did not fit through the 7fr gauges.The shaft did not pass through the 7.25fr gauge.Measurements of the tip and shaft were taken, the tip od, shaft between r1/r2 and r2/r3 were within specification.Shaft proximal to tip and distal to ring 1 was above specifications.The shaft length was within specification.The gap between the proximal end of the tip and the distal end of e2 is approximately 2cm.X-rays of the distal tip did not reveal any abnormalities.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The investigation conclusion is handling damage as the complaint was caused by handling of the device or portion of the device without direct patient contact.(b)(4).
