Myosure disposable arrived at hologic costa rica on (b)(6) and was tested by the pms group.Visual inspection was performed, and everything worked as intended, no missing or damaged components.The mechanical testing was performed, and the blade could reciprocate the movement, but never returned to closed position.The device was dissected, and the inner cannula was corroded, which created resistance to the cannula movement which caused the blade not returning to closed position which suggested that the blade might had dissembled from the device and give the impression of being in the uterine cavity.No pieces from the device were missing.Hence the complaint about parts of the device inside the uterine cannot be confirmed.A device history record (dhr) review was conducted for the reported lot/serial number.The device was released meeting all qa specifications.We are currently unable to establish a relationship between the device and the issue reported.
