(b)(4).The device was returned for evaluation.The handshake connection, sheath, coil, and burr were microscopically and visually examined.Inspection of the device observed a kink in the coil at the handshake connection.The coil was pulled out of the housing about 20cm.At the distal end of the catheter, the coil was stretched and broken with the burr detached.The burr was not returned for analysis.The sheath was torn at the distal end.The end of the sheath was jagged and damaged, which indicates that the tensile overload was involved.Functional testing was done with a test rotawire; however, it was not able to be inserted through the broken coil or the kinked coil.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.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).
