A review of device history record (dhr) was conducted and there were no manufacturing rejects or anomalies recorded in the dhr affecting released product.The sheaths released to inventory passed all in-process and qa final inspection steps before shipping to the customer, customer including visual, dimensional and leak testing.As per the procedure, adelante s2s introducer sheath in-process and final inspection, it instructs "with naked eye at a distance of 12" to 18", verify the assembled sheath matches the drawing.Ensure parts are free of kinks, cracks, splits, sinks, excessive flash, loose/embedded fm, or any other damages." as the procedure introducer set, silicone seal slitting states, "the operator visually inspects all the slit seals for defects 100 percent with a microscope.Also, a leak test is performed on 100 percent of the introducer sheaths by qa per the leak test - introducer with seal- electronic tester procedure.Two 14f abiomed introducer sheaths, one 13 cm and one 25 cm in length were returned from the customer along with one 33 cm long dilator.There were no other accessories.Blood was found on all components.Upon evaluation of the 25 cm long sheath, there was damage found around the circumference of the distal tip edge that looked like a bend/kink as stated in the complaint.The distal tip of the 33 cm dilator is curved as well.Putting any excessive stress on the sheath may cause it to kink, deform or break.It is believed the sheath and dilator were subjected to stresses beyond their capabilities during use out in the field.Upon evaluation of the 13 cm long sheath, it was found that the insertion point into the hemostasis valve was identified to be considerably off center of the helical cuts, creating a hole in the valve.This caused the blood to ooze out of the hemostasis valve.It is stated in the instructions for use (ifu) never advance or withdraw guidewire or sheath when resistance is met.Determine cause by fluoroscopy and take remedial action.When injecting or aspirating through the sheath, use the sideport only.It also indicates "when assembling the sheath and dilator, care must be taken to insert the dilator tip straight through the center of the valve membrane in order to prevent inadvertent puncturing of the membrane." returned device analysis reveals two 14f introducer sheaths and one dilator that are within manufacturing specifications.The reason for return cannot confirmed.No manufacturing defects were found.Based on the investigation, a capa is not required as findings did not identify a design, labeling or manufacturing non-conformity.In addition, there was no new failure mode identified and the risk remains acceptable for both events reported.The event will be re-evaluated if additional information becomes available.Oscor will continue to monitor this event type and risk.
