Final device investigation found that the sleeve of an ethb12lt was returned with the obturator and stability cone of an ethh12lp.The sleeve had blood residue indicating clinical use.Upon evaluation, the locking mechanism of the sleeve operated as intended.However, the locking mechanism of the stability cone did not function due to what appeared to be excessive wear on the mechanism parts.The sleeve was then pressure tested.The sleeve showed no signs of leaking when tested along, but did show signs of leaking when a test obturator was inserted into the device.No lot number was provided with the device, so the device history record could not be reviewed for discrepancies.
