IMPLANTABLE SYSTEM WITH SECURE REMOTE CONTROL
First Claim
1. A fluid flow system for a patient comprising:
- a controller comprising;
a processing unit comprising a signal generator and one or more pump operational parameters, wherein the signal generator is constructed and arranged to deliver a drive signal; and
a battery constructed and arranged to provide power to the processing unit;
an implantable pump assembly constructed and arranged to receive the drive signal from the processing unit and propel fluid based on the drive signal;
a security key generator constructed and arranged to produce a unique identifier;
a remote communication device comprising a code generator and the unique identifier produced by the security key generator, wherein the code generator is constructed and arranged to produce encrypted commands based on the unique identifier; and
a local communication device comprising the unique identifier;
wherein the local communication device is constructed and arranged to receive the encrypted commands from the remote communication device and modify a pump operational parameter of the processing unit based on the received encrypted command.

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

28. A method of modifying an operational parameter of a fluid flow system comprising:
-
providing a fluid flow system comprising; a controller comprising; a processing unit comprising a signal generator and one or more pump operational parameters, wherein the signal generator is constructed and arranged to deliver a drive signal; and a battery constructed and arranged to provide power to the processing unit; an implantable pump assembly constructed and arranged to receive the drive signal from the processing unit and propel fluid based on the drive signal; a security key generator constructed and arranged to produce a unique identifier; a remote communication device comprising the unique identifier produced by the security key generator and a code generator, wherein the code generator is constructed and arranged to produce encrypted commands based on the unique identifier; and a local communication device comprising the unique identifier;
wherein the local communication device is constructed and arranged to receive the encrypted commands from the remote communication device and modify a pump operational parameter of the processing unit based on the received encrypted command;having the security key generator produce the unique identifier; incorporating the unique identifier into the remote communication device and the local communication device; generating an encrypted command with the remote communication device that includes a proposed modification to one or more pump operational parameters; receiving the encrypted command with the local communication device and confirming the acceptability of the encrypted command; and modifying the one or more pump operational parameters of the processing unit if the encrypted command acceptability is confirmed. - View Dependent Claims (29, 30)
