Event Description

As reported, the white tube tip of a 5f mynx control vascular closure device (vcd) was damaged and did not enter the sheath, so it could not be used.There was no reported patient injury.The vcd was used after completing a trans femoral cerebral angiogram.Additional information was requested but not provided.The device was not returned for evaluation as previously expected.Addendum: on product evaluation a swelling condition of the sealant resulted in the protrusion of the sealant from the sealant sleeves.

Manufacturer Narrative

As reported, the white tube tip of a 5f mynx control vascular closure device (vcd) was damaged and did not enter the sheath, so it could not be used.There was no reported patient injury.The vcd was used after completing a trans-femoral cerebral angiogram.Additional information was requested but not provided.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 button 1 and button 2 were not depressed, the sealant remained in its manufactured position, fully covered by the sealant outer sleeve assembly that did not show any evidence or traces of the damaged condition reported as received.Nevertheless, exposure to blood was denoted.No other damages/anomalies were observed with the returned device during the unaided eye visual inspection.Neither the syringe nor the sheath used were returned with the device reported.Per dimensional analysis, the slit length was verified and noted to be within specification.Per functional analysis, the cordis lab¿s applicable catheter sheath introducer (csi) was used for a functional insertion/ withdrawal test where no resistance or friction was perceived during this analysis when the device was passed through the csi.Per microscopic analysis, visual inspection at high magnification showed that the sealant sleeves were in their manufactured positions, fully covering the sealant portion that was not protruded as it is expected per the positions of buttons 1 and 2 as received.Nevertheless, the sealant showed swelling evidence that could be attributable to the possible premature blood exposure resulting in the partial protrusion portion exposed of the sealant.A functional deployment mechanism test was executed due to the sealant premature protrusion condition that was appreciated only in the magnified visual inspection.The reported event of ¿sealant sleeves (cartridge assembly)-damaged¿ was not confirmed through analysis of the returned device since there were no traces of damage noted.However, a condition was noted in the returned device of ¿mynx control system-deployment difficulty-premature¿ due to the premature exposure observed related to the swelling sealant the exact cause of the observed condition could not be conclusively determined during analysis.Based on the limited 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 possibly contributed to the premature exposure/swelling 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 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 instructions for use (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 failure observed could be related to the design or manufacturing process of the unit.Therefore, no corrective/preventative actions will be taken at this time.
