Abstract: A bio-magnetic system for moving a constituent of a human body includes at least one magnetically responsive member having an attachment mechanism including collagen which is bound with an epithelium of a moveable constituent in the human body. A bio-magnetic drive system for moving a constituent of a human body includes a plurality of magnetic microbeads connected in vivo to a moveable constituent of a human body, and it also includes a magnetic field source disposed in operative association with the microbeads but remote from the microbeads and the moveable constituent to provide a magnetic field to move the microbeads. A method for moving a constituent in a human body includes transmitting a signal to interact with a plurality of microbeads connected to a constituent in a human body such that the connected microbeads and constituent in the human body move in response.

Abstract: An attachment device for a middle ear implant includes a first loop adapted to mount over structure in a middle ear. A second loop is connected to the first loop and adapted to mount over an object for use in the middle ear. A related method includes sliding a loop along at least part of a middle ear ossicle or prosthesis such that an object connected to the loop is disposed adjacent the ossicle or prosthesis. A method of testing for a magnet in a middle ear of a patient includes: inserting a coil at least into an outer ear canal of the patient adjacent the middle ear having the magnet; selectably aiming the coil relative to the middle ear; driving the coil with an alternating current signal at each selected aiming; obtaining at least one indication in response to driving the coil with an alternating current signal at each selected aiming; and determining a functional or positional characteristic of the magnet from the obtained indication. This method can be implemented with a plurality of coils.
