IMPLANTABLE SYSTEM WITH SECURE REMOTE CONTROL

摘要

A fluid flow system (10) for a patient comprises a controller (100) and an implantable pump assembly (50). The controller (100) comprises a processing unit (110) and a battery (161 ). The processing unit (110) includes a signal generator (115) and one or more pump operational parameters. The signal generator (115) provides a drive signal. The battery (161 ) provides power to the processing unit (110). The implantable pump assembly (50) receives the drive signal from the processing unit (110) and propels fluid based on the drive signal. The system (10) includes a local communication device (400) and a remote communication device (300) that each include a unique identifier produced by a security key generator (500). The remote communication device (300) includes a code generator (310) that produces encrypted commands. The local communication device (400) receives the encrypted commands and modifies a pump operational parameter of the processing unit (110) based on the received encrypted command.
