Event Description

Device report from synthes (b)(4) reports an event in (b)(6) as follows: it was reported there was leakage of balloon of the stent during expanding.The stent could only be expanded three to four millimeters.The surgeon tried to expand the stent with the trial balloon, due to a scoliotic position of the vertebra caused by the leaking balloon; this almost worked.When the surgeon tried to pull the balloon back, the balloon burst and parts of it remained in the vertebra.The surgery was prolonged about ten (10) minutes.The patient outcome is reported as okay.There are still some parts of the balloon in the vertebra that could not be removed.The vertebra was also filled with cement afterwards.The planned surgery was finished with a good anatomical alignment and outcome.The only problem is the parts of the balloon in the vertebra.This is report 1 of 1 for (b)(4).

Manufacturer Narrative

A manufacturing evaluation was completed: two instruments were returned, one system appears intact, and by the other system the balloon has burst transversally.The review of the manufacturing history of the production lot did not reveal any nonconformity.The complaint instrument was manufactured according to specifications and successfully passed all in-process inspections as well as the final inspection.The physician was unable to fully expand the stent due to a leakage of the delivery balloon.He tried to further expand the stent by introducing the vb balloon and using it for a post-dilatation.During this procedure the balloon burst and fractured when it was attempted to retrieve it.The technical analysis of the complaint instruments has shown that the stent delivery system is leaking when > 5 atm pressure is applied.The leakage site is located within a deep scratch near the tip of the balloon.The vb balloon on the other hand had burst in a transversal manner and the distal part of the balloon remained inside the patient.No clear origin of the fracture could be identified at the fracture edge, but several deep scratches were observed on the balloon surface.Based on the information available it appears that the complaint event occurred most probably due to unfavorable circumstances during the intervention (i.E.Balloon damage due to sharp solid bone fragments).Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
