Abstract
The labelling of a range of catheters introducers drains balloons stents and endografts was examined Products were chosen to achieve a broad range of French sizes from several manufacturers To assess manufacturing accuracy eight devices were selected for measurement using a laser micrometer The external diameters of three specimens of each device were measured at centimeter intervals along the length of the device to ensure uniformityOur results demonstrate wide variation in the interpretation of the French scale by different manufacturers of medical devices This has the potential to lead to problems using coaxial systems especially when the products are from different manufacturers It is recommended that standard labelling should be employed by all manufacturers conveying specific details of the equipment Given the wide variation in the interpretation of the French scale our opinion is that this scale either needs to be abandoned or be strictly defined and followed
