As reported, a 6f 10cm transradial rain sheath separated about 1cm from the hub inside a vein when the physician went to remove the sheath.A surgeon was called, and the patient had a cut-down procedure to remove the remaining cannula of the sheath.The procedure was aborted due to the complication.The patient is doing well after the procedure.A physician went to gain right radial access and stuck the vein.The physician then proceeded and placed a 6f rain transradial sheath inside the vein.The physician then tried to gain access to the right radial artery and did successfully.A 6f rain sheath was placed inside of the artery.An unknown j-wire was used.Getting arterial access potentially nicked the venous sheath in place and the integrity of the cannula "may have been damaged causing the break in the sheath upon removal".There were no damages noted to the device prior to using it.There was no calcification or tortuosity at the insertion vessel site.There were no specific patient anatomical anomalies noted at the insertion site.The device was flushed prior to use.The vessel dilator was snapped into place at the hub.Other procedural details were requested but are unknown, unavailable, not answered, or not applicable.The device will be returned for evaluation.

After further review of additional information received the following sections have been updated accordingly: d2, g1, g3, g6, h1, h2, h3 and h6.As reported, a 6f 10cm transradial rain sheath separated about 1cm from the hub inside a vein when the physician went to remove the sheath.A surgeon was called, and the patient had a cut-down procedure to remove the remaining cannula of the sheath.The procedure was aborted due to the complication.The patient is doing well after the procedure.A physician went to gain right radial access and stuck the vein.The physician then proceeded and placed a 6f rain transradial sheath inside the vein.The physician then tried to gain access to the right radial artery and did successfully.A 6f rain sheath was placed inside the artery.An unknown j-wire was used.Getting arterial access potentially nicked the venous sheath in place and the integrity of the cannula "may have been damaged causing the break in the sheath upon removal." there were no damages noted to the device prior to using it.There was no calcification or tortuosity at the insertion vessel site.There were no specific patient anatomical anomalies noted at the insertion site.The device was flushed prior to use.The vessel dilator was snapped into place at the hub.A non-sterile ¿6f,10cm sw radial¿ was received for analysis.Only the catheter sheath introducer (csi) was returned, and it presented with a separated cannula located approximately 8.5 cm from the distal tip.The separated piece was returned for analysis.Inner diameter (id) and outer diameter (od) measurements were taken near the damages and were found within specification.Sem analysis was not performed because the damages associated with the separation are visible with the magnification obtained with a vision system.The separated area was inspected with a vision system and presented evidence of elongations and plastic deformation.Additionally, a puncture was observed near the separated edge of the proximal segment.The puncture presents with plastic deformation and material elongations with a direction toward the inside of the cannula.A product history record (phr) review of lot 18183120 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿cannula~separated" was confirmed, the unit was received with the cannula separated into two pieces.Additionally, a puncture was observed on the cannula.The plastic deformation found at the puncture site suggests the unit was damaged with a sharp object from the outside toward the inside of the cannula.The elongations and plastic deformation found on the material are commonly associated with separations caused by material tensile overload.Therefore, it is assumed that the device was induced to a tensile force that exceeded the material yield strength prior to the rupture.Procedural/handling factors may have contributed to the reported event.Users are trained to inspect for signs of damage prior to and during use.Any product with damage is not to be used.Information for safety is provided in the products labeling with the intent to make the user aware of the risks.According to the instructions for use (ifu), although not intended as a mitigation of risk, ¿do not scratch the sheath with needle point, cutting tool, or other edged tools.Once all catheters and wires are removed, remove the sheath when clinically indicated by placing compression on the vessel above the puncture site, and slowly withdraw the csi.¿ based on the information available and the phr review, there is no indication that the event is related to the device design or manufacturing process.Therefore, no preventative or corrective actions will be taken at this time.
