Additional Manufacturer Narrative
This supplemental report is being submitted with an update to sections: h6 device codes, h6 component codes, h6 evaluation method codes, h6 evaluation result codes, h6 evaluation conclusion codes.Device analysis the 14f isleeve introducer sheath was returned and device analysis was performed by a boston scientific quality technician.The returned device consisted of a 14f isleeve introducer sheath with the dilator pushed completely through the sheath and protruded from the sheath tip.The device was visually and microscopically evaluated.The 14f isleeve introducer sheath was kinked approximately 17.5cm distal of the strain relief.All three (3) expansion seams were expanded with the tip split at the seam.The expanded seams and tip of the 14f isleeve introducer sheath occurred along the seam line and is expected during use of the device; therefore, this is not considered device damage.At two expansion seam lines the tip of the 14f isleeve introducer sheath was split along either side of the seam causing a portion of the tip to protrude upward creating a flap at both locations.No sheath liner tear was present.
