Manufacturer Narrative
|
The device history record (dhr) review confirmed that the device met all material, assembly and performance specifications.During the analysis of the returned device, it was revealed that the main coil was kinked, stretched and prematurely detached inside the patient.Functional testing could not be performed due to the condition of the returned device.Additional information indicates that the coil was confirmed to be in good condition after unpacking and preparation and there is no indication of a use error.Inspection of the main coil detachment zone indicates that the main coil was partially detached and then physically broke.It is likely that procedural factors contributed to the reported detachment issues and subsequent migration.Therefore an assignable cause of procedural factors will be assigned to the reported and analyzed defects.As the issue is associated with a product that meets the design and manufacture specifications and was used in accordance with the dfu (direction for use) but due to procedural and/or anatomical factors during use, the product performance was limited.
