Inductively Powered Remotely Adjustable Gastric Banding System

摘要

A power management system provides wireless power to operate components of a remotely adjustable gastric banding system. The power management system comprises an external power component transmitting power, and an implantable power management component receiving power and converting the power for use in powering one or more components of the remotely adjustable gastric banding system, such as a pump. The internal power management component and the external power component may be tunable. By utilizing the power management system, implantable batteries may be eliminated.
