SYSTEM FOR INFORMATIONAL MAGNETIC FEEDBACK IN ADJUSTABLE IMPLANTS

摘要

According to some embodiments, systems and methods are provided for non-invasively detecting the force generated by a non-invasively adjustable implantable medical device and/or a change in dimension of a non-invasively adjustable implantable medical device. Some of the systems include a non-invasively adjustable implant, which includes a driven magnet, and an external adjustment device, which includes one or more driving magnets and one or more Hall effect sensors. The Hall effect sensors of the external adjustment device are configured to detect changes in the magnetic field between the driven magnet of the non-invasively adjustable implant and the driving magnet(s) of the external adjustment device. Changes in the magnetic fields may be used to calculate the force generated by and/or a change in dimension of the non-invasively adjustable implantable medical device.

主权项

1. A remote control for adjusting a medical implant, comprising:
a driver, configured to transmit a wireless drive signal to adjust an implanted medical implant, wherein adjustment of the medical implant comprises one or more of generating a force with the medical implant and changing a dimension of the medical implant; at least one sensor, configured to sense a response of the implant to the drive signal; and an output configured to report one or more of a force generated by the medical implant and a change in dimension of the medical implant, in response to the drive signal.
