Communication enables operations such as programming, and the sending and retrieval of data between the Merlin 2 PCS and the implanted device. The Merlin 2 PCS provides access to the implantable device but does not provide therapy: all therapy is delivered via the implantable device. The Merlin 2 PCS provides visual and mechanical interfaces to medical professionals so that they may assess patient conditions and the functioning of the implantable device. As per the risk analysis, there have been no unacceptable risks identified in evaluating the clinical functions of the product and associated risks. The following safety guidelines should be kept under consideration:

During external interference, such as electromagnetic interference, the programmer will not undergo any permanent damages that prevents it from communicating with the implantable device, although the programmer display and communication speed may be affected. The programmer is able to reestablish and recover display and communication speeds, either automatically or with manual intervention, once the external interreference is removed. The programmer is not expected to function if the unit is damaged. NOTE: For single fault conditions, see Troubleshooting (page 15). Data Security Abbott Medical takes a broad and deep approach to ensuring the safety, security and privacy of the patient information and data on our devices and systems connecting patients to healthcare providers and clinics. Patients, clinical staff, and hospital IT staff do not need to configure the pulse generator or take any special action, for example firewall use, to safeguard patient information and device data. The Merlin 2 PCS programmer logs security events, for example a failed installation of programmer software, and stores these log files on disk. These files can then be analyzed by Abbott Medical personnel during system forensics. They are not meant to be analyzed by the clinic's information technology personnel. All safeguards for the devices will be provided throughout the stated warranty period or until a replacement product is available. In the rare event of a cybersecurity attack on the programmer that affects its ability to program the pulse generator, implanted device therapy will continue. Abbott Medical encourages the clinics to allow only authorized healthcare providers to use the Merlin 2 PCS, for example by requiring badged access to programmer locations. The cybersecurity bill of materials (CBOM) is available upon request. 19 Bluetooth Communication For Bluetooth Low Energy wireless communication, the Merlin 2 PCS and Abbott Medical implantable devices should be within 8.25 feet (2.5 meters) in normal use; 6.6 feet (2 meters] when used with insertable cardiac monitors. The programmer uses BLE with authentication methods to ensure that the programmer communicates only with Abbott Medical authorized products. The integrity and confidentiality of all data-in-transit during BLE communication is protected by multiple levels of encryption. The Merlin 2 PCS contains the certified Bluetooth Low Energy wireless communication. BLE performance could be affected by the programmer's enclosure. Inductive Communication Inductive Communication is a short-range communication channel that protects patient information by the proximity of the telemetry wand to the device. Only authorized healthcare providers should place the inductive wand over the device. RF Communication To begin Merlin 2 PCS use, the clinician places the programmer's inductive telemetry wand over the patient's implanted device and initiates communication. The inductive wand has a range of less than 2.75 inches (7 centimeters) in normal use. The Merlin 2 PCS then switches to Medical Implant Communications Service (MICS)-based (RF) telemetry if the implanted device supports it. The RF telemetry range is less than 8.25 feet (2.5 meters) in normal use. Abbott Medical implantable devices introduced in 2010 and later use proprietary communications protocol based on magnetic induction and, for certain models, an MICS-based protocol. This protocol prevents unauthorized device communication and recording and protects sensitive patient information using:

An authentication algorithm Data encryption Electromagnetic Compatibility NOTE: The implanted device authenticates telemetry communication before accepting changes to programmed therapy. The Merlin 2 PCS and the Merlin Antenna require special precautions with regard to electromagnetic compatibility (EMC) and should be used in accordance with the information provided in this manual. The Merlin 2 PCS and the Merlin Antenna comply with the requirements of the EMC international standard IEC 60601-1-2 when used with the cables listed in the Accessories table (page 27).
