Manufacturer Narrative

The device is expected to be returned for investigation.It has not yet been received.A follow-up report will be submitted with all additional relevant information.Na.

Event Description

It was reported that the procedure was performed to treat a de novo lesion in the moderately calcified.Mildly tortuous, 90% stenosed right coronary artery.A 2.75x33mm xience skypoint stent delivery system (sds) was advanced while experiencing resistance with the anatomy.The balloon was inflated once to 4 atmospheres when the balloon ruptured, and the sds was removed without resistance.An unspecified balloon was used to successfully complete the procedure.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

Manufacturer Narrative

A visual and functional inspection was performed on the returned device.The reported split, cut or torn material was confirmed.The reported difficult to advance/position could not be tested as it was based on operational circumstances.It should be noted that the xience skypoint, everolimus eluting coronary stent system (eecss), electronic instructions for use states: prepare an inflation device / syringe with diluted contrast medium.Attach an inflation device / syringe to the stopcock; attach it to the inflation port.With the tip down, orient the delivery system vertically.Open the stopcock to delivery system; pull negative for 30 seconds; release to neutral for contrast fill.Close the stopcock to the delivery system; purge the inflation device / syringe of all air.Repeat steps until all air is expelled.It is unknown if the ifu deviation directly caused or contributed to the reported difficulties.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other incidents.The investigation determined the reported difficult to advance/position appears to be related to the operational context of the procedure, as it is likely the device interacted with the moderately calcified, mildly tortuous, 90% stenosed lesion during advancement, as resistance was noted, resulting in the reported difficult to advance/position and noted stent damage (proximal and distal flared stent struts).However, the investigation was unable to determine a conclusive cause for the reported split, cut or torn material.The initially reported balloon rupture was actually an inner member tear.The scanning electron microscopy (sem) analysis concluded that the inner member exhibited a leak protruding in the proximal direction.The inner surface exhibited pushed material/gouging on the distal side leading to the leak.Material thinning and tearing were documented at the leak edges.The inner member failure may be attributed to mechanical damage to the inner surface.Potential factors that may contribute to split, cut or torn material include, but are not limited to, interaction with accessory devices, mishandling during manufacturing, during receiving/storage at the account, and/or during removal from packaging, preparation of the device and/or stent/stylet removal.It is possible the device interacted with accessory devices during the procedure, causing the reported split, cut or torn material and noted scratched material, ultimately contributing to the noted leak in the inner member; however, this cannot be confirmed.There is no indication of a product quality issue with respect to the design, manufacture or labeling of the device.H6: medical device problem code 1546 was removed.

Event Description

Subsequent to the initially filed report, the following information was received: the reported balloon rupture was actually an inner member tear.No additional information was provided.
