A hand-operated, non-sterile, magnetic device designed to be used by a patient and a healthcare professional to switch an active implantable device (e.g., pulse generator, implantable cardiac monitor) on and off. It typically consists of a small portable magnet (e.g., strontium ferrite) coated with an epoxy that can be carried in the pocket or a handbag (purse) of a patient for convenient access. It is placed by the patient against the skin directly over the site of the implant and turned as prescribed by the manufacturer. This is a reusable device.
