Manufacturer Narrative

(b)(4).
The sample was provided and an evaluation was performed.
The instrument was manufactured in june of 2007.
The instrument looks worn and shows repeated repair work performed by unauthorized third party repair companies, such as grinding at the tip as well as on the glider and the main shaft parts.
Apparently the screw was not secured appropriately after repair.
In addition, the screw returned with the device is not the original screw as per the supplier¿s device master record and device history record.
The customer should train its staff that the screws must be checked for tightness after cleaning.
There have been no issues identified with the material or manufacturing process.
A review of the device history records (dhr) did not identify and issues that would have contributed to the reported issue.
