Event or Problem Description
An orsiro drug-eluting stent system was selected for treatment.The balloon could not be inflated, and therefore the stent could not be deployed.
Additional Manufacturer Narrative
Combination product: yes the returned product was subjected to a technical analysis and the corresponding production documentation was reviewed to establish whether a deviation from the manufacturing process could be the cause for this event.The technical investigation of the returned instrument revealed that the balloon has not been inflated but both balloon shoulders are slightly unfolded.The stent is also slightly opened at both ends.Microscopic inspection revealed a constriction of the outer shaft at the proximal balloon weld.The findings indicate that the shaft deformations were most likely caused by a tensile force which has been applied to the distal part of the instrument.A reference transportation wire and a reference guidewire could be introduced into the guidewire lumen of the instrument.Review of the production documentation confirmed that the instrument was manufactured according to specifications and passed all in-process and final inspections.In addition to visual inspections each instrument is inflated and tested for air tightness by means of a helium leakage test.Based on the conducted investigations, no manufacturing or material related root cause could be determined.The root cause for the complaint event is most likely related to the handling during the preparations for the intervention.It should be noted that, according to the ifu, the user is advised to exercise care during device handling to reduce the possibility of accidental breakage, bending, kinking of the stent system shaft.
