Reason for recall
Supplemental information provided with devices indicates that the subdural electrodes, depth electrodes, and anchor bolts are approved for use in the MR environment, for which they are not approved for such use.
Products marketed as supplements sometimes contain undeclared prescription drug ingredients such as sildenafil or sibutramine. These can interact dangerously with other medicines.
