Patent ID: 7476195

Claim:
A remote telemetry system for an implantable apparatus for controlling fluid flow within a host body, the telemetry system comprising: a signaling mechanism for sending and receiving signals to and from a control unit implanted in a host body in order to monitor the operation of the implantable apparatus, wherein based on information received from the control unit the telemetry system sends signals to the control unit for altering or maintaining operating settings of the implantable apparatus, said system further comprising at least one sensor to monitor actions of the implantable apparatus on the host body, and a mechanism to interrogate said sensor to permit feedback on the sensed data, wherein at least one of said sensors is provided to monitor pressure exerted by a moveable part of said implantable apparatus on a part of said host body, the feedback on the sensed data causing commands to be sent to said control unit to alter or maintain the range of movement or position of said moveable part within the host body.
