Manufacturer Narrative

As reported, the sealant protection sleeve of a 5f mynx control vascular closure device (vcd) was damaged and could not enter the sheath.There was no reported patient injury.The physician used the device for hemostasis in a transfemoral cerebral angiogram procedure.The procedure used a retrograde approach.The deployer was certified in the use of the mynx device.The femoral artery¿s suitability was verified on angiography, including the insertion angle (30-45 degrees) of the vascular sheath introducer.The vessel diameter was verified to be greater than or equal to 5mm in diameter.There was moderate vessel tortuosity.Hemostasis was achieved with another mynx device.The device was stored and prepped per the instructions for use (ifu).No excess force was used during insertion of the device.A non-sterile mynx control vascular closure device 5f involved in the reported complaint was returned for investigation.Visual inspection of the received device showed that the button 1 and button 2 were not depressed.The sealant remained in its manufactured position and exposed due to the conditions of the sealant outer sleeve assembly that presented damage evidence that could be related to the reported event.The exposed sealant condition resulted in a swelled sealant condition that was covered in blood completely.The sheath used in the procedure was not returned with the device to be evaluated.The dimensional analysis of the slit length could not be measured due to the observed conditions of the device.A functional test for a catheter sheath introducer (csi) insertion/withdrawal analysis could not be executed due to the conditions of the sealant sleeves.Additionally, due to the exposed condition observed of the sealant that could be concluded as a premature deployment malfunction, a deployment mechanism simulation was performed.During the deployment simulation, the device received showed that the deployment mechanism was not compromised.After depressing button 1 and 2 in the unit, the sealant was deployed and the balloon was fully retracted as expected per the unit¿s intended use mechanism.Per microscopic analysis, visual inspection at high magnification showed that the sealant outer sleeve assembly damage evidence could be described as a frayed split torn condition.The reported event of ¿sealant sleeves (cartridge assembly)-damaged¿ was confirmed through analysis of the returned device as the sealant sleeve assembly had a condition observed as ¿sealant sleeves (cartridge assembly) frayed split torn.¿ additionally, a condition was noted in the returned device of ¿mynx control system deployment difficulty premature¿ due to the exposed sealant from the damaged sleeves.The exact cause of the observed conditions could not be conclusively determined during analysis.Based on the information available for review and product analysis, it is difficult to determine what factors may have contributed to the issue experienced.However, procedural handling factors (although it was reported that excessive force was not used during insertion), and or the condition of the sheath (the access vessel had moderate tortuosity; however, the sheath was not returned) possibly contributed to the damaged condition of the sealant sleeves, the impedance experienced during insertion, and the subsequent premature exposure of the sealant.It should be noted that the mynx control device is manufactured with a slit at the end of the catheter cartridge tubing.The outer sleeve assembly is assembled with 2 side slit overlapping outer sleeves.The sealant is placed right under the outer sleeve assembly and is protected from exposing prematurely.The slits on the outer sleeve assembly are designed to decrease unsheathing force and increase deployment reliability.Refer to the diagram of the mynx control vcd within the ifu displaying the sealant sleeve with slit.If the outer sleeve is damaged kinked during prepping phase and or insertion into sheath, it could cause the sealant to be exposed swollen prematurely and or obstruct the device path and prevent the device from being inserted into the procedural sheath.As warned in the ifu, which is not intended as a mitigation, ¿do not use if components or packaging appear to be damaged or defective or if any portion of the packaging has been previously opened.¿ additionally, the ifu states ¿step 1: position balloon, insert the mynx control vcd into the procedural sheath through the sheath valve.Advance the catheter until the sheath catch nears the hub of the sheath.Rotate the sheath catch as needed to hook onto the side port of the procedural sheath.¿ neither the product analysis, nor the information available for review suggest that the failures could be related to the design or manufacturing process of the unit.Therefore, no corrective preventative actions will be taken at this time.
