Manufacturer Narrative

This device is used for treatment not diagnosis.The ventricular assist system is indicated for use as a bridge to cardiac transplantation and destination therapy in patients who are at risk of death from refractory end-stage left ventricular heart failure.The system is designed for in-hospital and out-of-hospital settings.

Event Description

It was reported that during the implant procedure, the outflow graft was attached on the back table and the strain relief was crooked so the perfusionist took the strain relief off and straightened the outflow graft, then reattached the outflow graft with a circumferential attached strain relief collar.After the pump was implanted and turned on, the outflow graft presented with a leak near the pump.The outflow graft was torn approximately 4 rings from the pump, near the strain relief connection.The surgeon took off the strain relief, cut the outflow graft behind the tear and reattached the outflow graft.The pump was then turned on and there were no further issues.The outflow graft remains in use.No patient complications have been reported as a result of this event.

Manufacturer Narrative

Correction: operator of device.If information is provided in the future, a supplemental report will be issued.

Manufacturer Narrative

The outflow graft was not returned for evaluation.Review of the manufacturing documentation confirmed that the associated component met all requirements for release.The reported event could not be confirmed because the component was not returned, and no supporting evidence was provided by the site to support the event.There is no evidence to suggest that a device malfunction caused or contributed to the reported event.An internal investigation evaluated tears in the outflow graft near the outflow of the pump under the strain relief.Based on this investigation, the most likely root cause of tears/cuts in the outflow graft has been attributed to design deficiencies.If information is provided in the future, a supplemental report will be issued.
