Event or Problem Description
|
|
It was reported that during the superion indirect decompression system (ids) implant procedure the driver was caught up on an obstruction.As a result, sagittal arching and excessive force were applied, causing the driver to break.All broken fragments were successfully removed.Additionally, the implant was not deploying properly and was getting stuck.The patient did not experience any reported complications.The damaged product was replaced and returned for analysis, and the procedure was completed without further issues.

The device was returned for analysis and a visual inspection found that the end of the driver was completely sheared off.The analysis results indicate the failure is associated to presence of excessive hydrogen in the instrument material.A review of the instructions for use (ifu) was performed, and it did not reveal any anomalies as it states to avoid application of excessive stress on instrumentation and do not force deployment or implant breakage or damage to bony structures may result.

A retroactive review of events within the quality system identified this record as requiring remediation, including reporting and submission of an initial emdr per applicable criteria.Boston scientific has opened a corrective and preventive action (capa 8647) investigation to determine the root cause for why an initial emdr was not previously submitted to the fda in accordance with boston scientific established mdr reporting process and fda adverse event reporting requirements.Information gained through these investigation efforts will be utilized to determine root cause and implement appropriate preventive action(s), as necessary.Fields h7 and h9 were updated.The device was returned for analysis and a visual inspection found that the end of the driver was completely sheared off.The analysis results indicate the failure is associated to presence of excessive hydrogen in the instrument material.A review of the instructions for use (ifu) was performed, and it did not reveal any anomalies as it states to avoid application of excessive stress on instrumentation and do not force deployment or implant breakage or damage to bony structures may result.
