Event Description

The following was reported to gore: on (b)(6) 2019 a surgeon implanted a gore® bio-a® tissue reinforcement in clean field ventral hernia repair using rives technique.It was reported the patient had a recurrence on (b)(6) 2019.On (b)(6) 2019 the surgeon re-operated on the patient and found that the device was broken in small pieces.The device was removed.A pp mesh was placed and in two days the patient was sent home in good condition.It was further reported the defect size was 3x4 cms on the midline suvra umbilical at the extraction site after robotic prostatectomy.Reportedly, the device was placed retrorectus sublay and was trimmed on 4 corners without reducing size.Additionally, vycril 1/0 was used to close the defect in the posterior fascia.Prolene 2/0 was used at the four corners.

Manufacturer Narrative

It was reported that a one device was implanted in the patient and subsequently removed.The exact lot number could not be confirmed, as it was reported that the lot was either 18833379 or 18817687.A review of the manufacturing paperwork verified that the both reported lots met all pre-release specifications.The explanted device is still being evaluated, the results will be provided in a follow-up report.

Manufacturer Narrative

Section h6 updated.The explanted device was returned for evaluation.The explant evaluation stated: the specimens were returned to w.L.Gore & associates for investigation.Submitted unfixed were approximately fourteen gore® bio-a® tissue reinforcement fragments.The submitted specimens were variably sized, fragile wafer-like pieces of biomaterial with jagged edges and generally devoid of tissue except scattered foci of red/brown staining.Histopathological examination of cross sections through the biomaterial specimens was performed.The fibers in the web were consistent with pga:tmc and appeared as expected at seven days post implantation.Analysis was limited due to poor tissue preservation with loss of stain and cellular details.Bacterial and fungal overgrowth is often associated with unfixed or poorly fixed tissue post removal.Enzyme digestion/ post digestion evaluation could not be performed due to the fragility of the material when processed.Appearance of the gore® bio-a® tissue reinforcement in vivo was not provided and degree of manipulation at time of explant was not provided.The torn/broken appearance of the edges of biomaterial appear consistent with a load-bearing application and/or physiologic degradation, as intended, of the device material.With the information provided the exact cause of tearing cannot be determined.
