St. Jude's Promote™ RF CRT-D and Current™ RF ICD
Tuesday, September 25, 2007
RF telemetry enables secure, remote communication between the implanted device and the programmers in a clinician's office or hospital.
The Promote RF CRT-D and Current RF ICD are built on St. Jude Medical's next generation "Unity" device platform. This consolidated electronics platform will enable St. Jude Medical to more quickly introduce devices with new features and diagnostics

Zarlink Simplifies Design of Medical Telemetry Systems Linking Implanted Devices and Monitoring Equipment

The ZLE70101 ADK includes all hardware and firmware required to permit customers to test the performance of the in-air communication link between implanted devices and external equipment. A commonly used application microcontroller is used for both the implant and base station platforms to enable rapid integration into a customer’s specific system design. An easy-to-use graphical user interface (GUI) running on a Windows-based PC controls and demonstrates the capabilities of a ZL70101-enabled medical telemetry system. The GUI interfaces to the MICS RF boards via a USB2.0 interface.
Could hackers attack the newest heart monitors?
implantable cardioverter-defibrillators (ICDs)
In general, cardiac telemetry systems seem to have four basic elements:
* A sensor device, either external or implanted, which monitors and captures various data from the patient’s heart.
* A monitoring device that receives the data from the sensor and transmits it to a remote recipient. Currently, cellular and land-line telephones seem to be preferred methods for longer distance data transmission, while WiFi may serve for transmission to a local monitoring station.
* An intermediary monitoring service often receives and stores the patient data in a secure server.
* Finally, the physician, nurse or other caregiver may use an electronic device — a cell phone, a personal computer, or even a personal digital assistant — to download the patient data from the server, either via the Internet or an in-house network connection. In some cases, the data may even arrive as a message on the physician’s office fax machine
Welch also emphasized that his and other firms’ remote cardiac telemetry devices are built to the WiFi standards crafted by the Institute of Electrical and Electronics Engineers.
"Data security and encryption is now built into the wireless standard," he says. "Even the standards bodies are embedding security right in the WiFi suite of standards. Not only can you not get access to the patient name, but you also can’t get access to the data."
In cases requiring enhanced security, technology firms can build in additional security measures for their devices, such as secure sockets layer connections, virtual private networks and higher-level encryption, he says.
Despite all of these security options, a skilled and determined hacker could still intercept a patient’s telemetry, says Welch, who adds, "It would be extraordinarily difficult for a hostile entity to gain access to the patient data."

As with other chips, RFID chips can be ROM
(read only) or RAM (read/write).
I would hazzard a guess that all implants are read/write, and don't need to be
replaced to update.
I know chips can be ROM or RAM. I help make them.
The chips are implanted with a large needle as shown on the show. The chips CANNOT be removed the same way. They must be removed surgically using a local anesthetic
