Model Number 9620TA26

Device Problems Burst Container or Vessel (1074); Difficult to Remove (1528); Detachment of Device or Device Component (2907)

Patient Problem No Clinical Signs, Symptoms or Conditions (4582)

Event Type  malfunction  

Manufacturer Narrative

Investigation is ongoing.

Event Description

As reported from our affiliates in (b)(6), during a case involving a 26mm sapien 3 transcatheter heart valve in aortic position by transapical approach, the delivery system balloon burst with 2 ml left before full inflation.The valve was fully expanded and functioning well with no pvl.The delivery system could not be easily removed because the balloon had separated into two pieces- though as reported, the ds and all balloon material were able to be successfully removed.At this time it is unknown if a snare or other device was utilized during the removal of the distal balloon; however, it was confirmed no surgical intervention was necessary.

Event Description

As reported from our affiliates in germany, during a case involving a 26mm sapien 3 transcatheter heart valve in aortic position by transapical approach, the delivery system balloon burst with 2 ml left before full inflation.The valve was fully expanded and functioning well with no pvl.The delivery system could not be easily removed because the balloon had separated into two pieces.The delivery system and all balloon material were able to be successfully removed without further surgical intervention, as the distal part of the balloon was fixed on the wire and could be removed.A snare was being prepared to be used, but it the end it was not necessary.

Manufacturer Narrative

The certitude delivery system was fully inspected and the following was observed: balloon burst was confirmed, both radially and longitudinally burst at approximately 54cm from nose tip.No balloon pieces appear missing.Guidewire lumen completely detached from the handle.Due to the nature of the complaint (burst balloon), no functional testing was able to be performed.The complaint was confirmed through visual inspection.Video was provided from site and the balloon was observed to have had burst at full inflation.The inflation balloon single wall thickness was measured along the edges of the burst location.A thickness deviating from the specification could be indicative of an issue during manufacturing of the component, as a thin wall could contribute to the observed burst.All measurements taken of the balloon single wall thickness met the specification.A device history review (dhr) was performed and did not reveal any manufacturing nonconformance that would have contributed to this complaint event.A review of the risk management documentation was performed, and the reported event is an anticipated risk of the transcatheter heart valve procedure, additional assessment of the failure mode is not required at this time.The complaint for balloon burst, withdrawal difficulty, and distal tip separation were confirmed by visual inspection of the returned device.However, no manufacturing non-conformance was identified during the evaluation.Dimensional inspection of the returned balloon revealed that the balloon wall thickness was within specification.No visual abnormalities were observed on the returned sample.An existing technical summary has been documented for root cause analysis on balloon bursts in a calcified landing zone.The technical summary provides a rationale as to why it is unlikely that a product defect or manufacturing non-conformance contributed to this type of event, including factors on why deployment of balloons on thv delivery systems are subject to increased risk of burst in a calcified landing zone.Per complaint description, "the certitude delivery system balloon burst almost at full inflation.Despite the balloon burst the valve was well implanted" and "it was not possible to remove the certitude delivery system through the sheath." the cases notes revealed the patient had "moderate" calcification at deployment area.The presence of calcification can create a challenging anatomy for balloon inflation.While the balloons are sufficiently designed and tested for rated burst pressures well above their inflation pressure, calcified nodules can compromise the structure of the balloon wall via following mechanisms such as puncture, local overstretching, open cell impingement, or stress concentration.As the balloon was burst, the altered balloon profile can be more susceptible to catch on the distal end of sheath tip which would have then led to the experienced retrieval difficulty.As a result, additional pull force/excessive device manipulation could have been applied to overcome the withdrawal difficulty which then led to the reported separation.In addition, the technical summary outlines the extensive manufacturing mitigations in place to prevent this type of malfunction (visual and dimensional inspections, leak testing, and functional balloon burst testing that occurs with every manufactured lot).These inspections and testing further support that it is unlikely that a defect present in manufacturing contributed to the complaint.The technical summary also outlines the instructions for valve deployment.It should be noted that these mitigations are still in place.Review of available information suggests that patient factors (calcification) contributed to the balloon burst while procedural factors (withdrawal of burst balloon, excessive manipulation) contributed to the withdrawal difficulty and separation.
