OFFICIAL DOCUMENT 1. INTRODUCTION 1.1. PURPOSE The purpose of the present document is to provide a high-level description of the structure and operation of the following sub-systems of Sorin Remote Monitoring System: the Smartview Monitor and the Implantable Medical Device. The Smartview Monitor (SM) is intended to collect patient’s clinical data from an Implantable Medical Device (IMD) and transfer them to data management system (Back Office server). The IMD is implanted into the patient’s body. The Smartview Monitor is installed at patient home and is intended to collect data from the IMD remotely in absence of physician according to scheduled operation. It is not intended to act as emergency response system. The connection between the Smartview Monitor and the implant is achieved through Radio-Frequency (RF) telemetry while the connection to the server is performed through the telephone line (fix or mobile net). Smartview Monitor Wired or wireless Paradym RF Telephone line RF Remote Monitoring Mains supply 1.2.

SYSTEM DESCRIPTION In the following sections, the Smartview Monitor and the Implantable Medical Device are described, highlighting their hardware functionalities and features. 1.3.1. SM OPERATING MODES The Monitor unit shall have two configurations to fit two different cases of use: 1) Home Monitoring. When it is installed at patient home in the context of RMS, with two different Back Office (BO) connection options a. PSTN modem when it is connected to BO through the fix telephone line b. GPRS modem when it is connected to BO through the mobile cellular telephone net. 2) Programmer RF Head. When it is installed in hospital and connected to the Orchestra Plus programmer through USB port for adding the RF telemetry feature to the Programmer itself. This mode is currently out of scope The Smartview Monitor communicates with the implanted device on two wireless RF bands: o ISM band (2.45- GHz) for communication initialization (implant wake-up) o MedRadio (402-405 MHz) band for data transfer 1.3.2. IMD OPERATING MODES The IMD communicates with the Smartview Monitor on two wireless RF bands: o ISM band (2.45 GHz) for communication initialization (implant wake-up) o MedRadio (402-405 MHz) band for data transfer FF00929A Document reference Dept. internal ref.

OFFICIAL DOCUMENT 1.3.3. IMD HARDWARE RF bi-band communication is done using the same ultra low consumption transceiver module connected through a stripe line and a hermetic bipolar feed-thru to a unique RF antenna loop embedded to the external connector of the device. The transceiver is driven by the CPU of the device upon dedicated interrupt request raised by the RF module. 2. SMARTVIEW MONITOR FUNCTIONAL DESCRITPTION In the following sections the Smartview Monitor is described, highlighting its Features and Operation. Note: IMD is also described through this section as a slave of the SM. 2.1. SMARTVIEW MONITOR OPERATION The summary of mission / operation of the Smartview Monitor is the following:  SM is a device to be installed in Patient Home. o Connection to telephone line (RTC version) o Connection to power line (wall plug adapter)  SM shall be activated after connecting it to power supply. Executes: o bootstrap; o self-diagnostic; o implant pairing (at first boot)  SM is paired through an automatic procedure to the Implant present at first boot  SM shall collect patient’s clinical data from Implanted device and transfer them to data management system (Back Office server).  The Implant data collection shall be performed according to 3 use cases: o Scheduled Patient Remote Follow-up o On Alert event/status evidenced by the Implant diagnostic features o On-Demand by Patient (if enabled)  SM shall give indication to user about its correct operation and the function in progress: o SM health is ok (HW and code) o Patient should stay close to SM o Communication to IMD or BO is in progress FF00929A Document reference Dept. internal ref.

OFFICIAL DOCUMENT 2.2.9. UPGRADES  SM shall download new firmwares from the location specified in the SM Configuration File, when it is available.  SM shall always report the running firmware.  The firmware switching mechanism shall revert to the old firmware in case of detected firmware errors 3. SMARTVIEW MONITOR TEST This section describes the rationale for the implementation of the Smartview Monitor operation to be used during the Qualification test. For EMC / environmental test a dedicated functional loop has been implemented in order to reproduce the basic operation of the SM in the same way the normal Application Program does but with an accelerated and simplified sequence. The rationale for this is:  The normal SM operation is based on task scheduler programmed by Back Office (RMS)  The SM is mainly in idle state for the main part of the day waiting for OD FU requests and to execute scheduled Alerts check or Follow-up IMD data collection  The BO server / application are not available during the SM Qualification test and it is anyway more convenient to not be BO dependent.

OFFICIAL DOCUMENT 3.1. SMARTVIEW MONITOR TEST UTILITIES Smartview Monitor test utilities vs. Program application layers: SM Application (high sw layer) Test software (test utilities) Drivers (low sw layer) Hardware (Electronic board) The Smartview Monitor standard compliance Qualification test is managed through dedicated software utilities including Basic Operation simulation and specific utilities to put the SM in specific operational condition. 3.2. SMARTVIEW MONITOR BASIC OPERATION Keeping into account what is described here above, the test functional loop involves:  SM installation (as for Patient Home). o Connection to telephone line (RTC version) o Connection to power line (wall plug adapter)  SM activation after connecting it to power supply. Executes: o bootstrap; o self-diagnostic;  SM opens a communication with Implantable device: o Check Alert execution  SM communicate the result to data management system (Back Office server).

OFFICIAL DOCUMENT  SM shall give indication to user about its correct operation and the function in progress: o SM health (HW and code) is ok on (Status LED) o Operation is in progress (OD LED) o Error in IMD or BO communication The SM tasks not included in the functional loop do not add operating conditions which are significant versus the test itself.

OFFICIAL DOCUMENT 3.3. FAILURES AND RECOVERY 3.3.1. ADMITTED FAILURES The following failures caused by external events (interferences, stress defined by the applicable standards) are admitted during the SM operation:  Detected IMD communication either errors or interruptions  Detected BO communication errors  System reset (excluding ICD) 3.3.2. NOT ADMITTED FAILURES The following failures, caused by external events (interferences, stress defined by the applicable standards) are not admitted during the SM operation:  Unrecoverable electronic or mechanical components failure  Unrecoverable software crashes  Code or configuration corruption  ICD reset 3.3.3. FAULTS RECOVERY Strategy for recovering the admitted faults:  IMD communication errors: retry and then communication to BO or user  Detected BO communication errors: retry  System reset: reboot and self diagnostic to check board and SW corruption FF00929A Document reference Dept. internal ref.

OFFICIAL DOCUMENT 4. IMD TEST This section describes the rationale for the implementation of the IMD operation to be used during the Qualification test. Even-though IMD could be tested in the same way the SM will be, for planning matter IMD shall be tested before SM and dedicated tools availability. For EMC / environmental test it has been implemented a dedicated RF Tool consisting-in connecting a RF head (SM + option) to a laptop via USB and running a special software tool. This tool consist-in providing every second a link called “ping” including identification header data control according to the private protocol. In this way and even though the application doesn’t require a continuous radio link (see below), we significantly increase the likelihood to trap any potential link stop during the immunity test time by raising a dedicated pop-up and confirm the RF communication can be restarted (only possible if no ICD reset occurred; reset being not admitted referring to section 3.3.2). Therefore, this feature reproduces the basic operations the IMD is designed to respond but with a continuous and simplified sequence. The rationale for this is:  The IMD operation is based on daily SM requests  The IMD is mainly in RF idle state for the main part of the day waiting for SM request and potential data sending when appropriate (Alert ready or Follow-up forced request).  The BO server / application is not available during the IMD Qualification test and it is anyway more convenient to not be BO dependent.
