Manufacturer Narrative

Manufacturer's investigation conclusion: the report of damage to the vectra vascular access graft could not be confirmed because no product was returned for investigation.The customer reported that the graft was placed under the skin and then pulled to adjust the position.This resulted in peeling and tearing to the outer layer.It was reported that no product would be returned for evaluation.Review of the manufacturing documentation for the graft lot found no deviations from manufacturing or quality assurance specifications, which includes visual and dimensional inspection of the grafts.The vectra vascular access graft instructions for use states that the graft should not be pulled (axially elongated) or stretched during handling at implantation.Excessive elongation or stretching of the graft will damage the microporous layers of the graft.Graft preparation and implantation are addressed in the vectra vascular access graft (vag) instructions for use (ifu).The ifu states that the graft should not be pulled (axially elongated) or stretched during handling at implantation.The graft should be trimmed long enough to prevent stress on the anastomosis and allow for a full range of body motion when implanted.Excessive elongation or stretching of the graft will damage the microporous layers of the graft.The ifu states that the vectra sheath tunneler should be used to minimize subcutaneous trauma and the force required to position the graft during implant.Tunneling permits graft placement without pulling - which can produce excessive forces that result in damage to the graft microporous layers.When positioning and trimming the graft, avoid those areas of less dense reinforcement, especially near the anastomotic end.The non-reinforced segment must be trimmed to allow for proper sizing of the graft.The tunneling section of the ifu states that the vectra vag tunnelers (except for the full curve tunneler which can only be used the 5mm) can be used with either the 5mm or 6mm vectra vag.Liberally irrigate the inside of the tunneler sheath as well as all surfaces of the graft with a sterile solution of normal physiologic saline to facilitate slipping the graft through the tunneler.Care should be taken to push rather than pull the graft through the tunneler.The vectra vag can be implanted using either a one-sheath or two-sheath technique and instructions for each are provided.These instructions includes steps that ¿insert the vectra vag into the subcutaneously placed sheath and gently push the graft through using a rotating motion if necessary, while irrigating liberally with sterile saline.¿ no further information was provided.The manufacturer is closing the file on this event.
