Event Type  Injury  

Event Description

It was reported that deflation issue and balloon rupture occurred requiring additional intervention.The patient presented with angina and underwent percutaneous coronary intervention.The target lesion was located in the mildly tortuous and mildly calcified right coronary artery.A 2.50 x 38mm synergy xd drug-eluting stent was advanced for treatment.However, during deployment, the stent balloon reached 4 atmospheres and would not inflate any further.The physician saw contrast travel distal to the stent and the blood came back into the inflation device, signaling a possible balloon rupture.Balloon deflation failed despite multiple attempts.The physician then cut the hub of the stent catheter and inserted a guide extension catheter over it, however, that did not work.The physician deep seeded the guide and was able to get some movement, which ultimately resulted in device removal.The stent found its way to the skin track along the femoral artery and was cut out with a scalpel.The device was removed in pieces and in deflated state.The procedure was completed using an alternate device, and no patient complications were reported.

Manufacturer Narrative

H6.Device codes- added shaft break.Device evaluated by mfr.: synergy xd mr us 2.50 x 38mm was returned for analysis and the following attributes were examined: as the manifold section of the device was not returned with the device, it is not possible to determine the manifold number.A visual, microscopic examination confirmed a dissection in the hypotube.The dissection was located towards the proximal end of the hypotube as the returned section of hypotube measured 120cm from the laser cut section to the break site.A visual and microscopic examination of the distal extrusion confirmed that a break exited in the midshaft section of the device, approximately 6.5cm distal to the hypotube bond.The distal section of the break, including the distal sections of the extrusion, balloon and tip were not received for analysis.A severely damaged, detached stent was received tangled to surgical scissors.
