(b)(4).The event is unlikely related to the strattice mesh and likely related to the patient's condition.As noted in the histological evaluation, partial incorporation of the device is seen is at the edges of the device.The central portion of the device is largely unincorporated in areas affected with chronic inflammatory infiltrate.Extensive destruction of the device collagen is seen in areas with adjacent foreign body granulomatous reaction.Special stains for fungi and bacteria are negative for organisms.Based on our internal review of the lot processing history, the lot met qc criteria for product release.No deviations were encountered in association with the event.No other complaints were reported to lifecell against the lot.Should additional relevant clinical details be received, a follow up mdr will be submitted.

It was reported to lifecell that a strattice mesh was used in an underlay fashion to repair a ventral hernia on (b)(6) 2014.The patient developed a recurrence of hernia.Upon exploration of the second post operative ventral hernia repair, (b)(6) 2015, the strattice mesh ripped down the middle resulting in exposure of the bowel under the abdominal wall.The strattice mesh was found to be well adhered and incorporated on the lateral sides of the abdomen.One dime-sized hole was seen in the strattice on the lower left side.To repair the defect, another strattice mesh was placed in the retro rectus space after performing lysis of adhesions (which were minimal).The previous strattice mesh was removed as best as possible.Phasix was used as an onlay.
