Figure 5: Task Force® CORE Viewer Detailed description of the device is to be found in Volume 10 (Device Description). #### 5.5.1 TFC Touchable Components The TFC components, which are deemed to be in direct contact with patient during measurements, are defined as the touchable components (TFC Fingersensor, TFC Forearm Controller Fixing Strap, TFC NBP Cuff and TFC Armsling). These components are intended to be in contact only with intact skin surfaces for a cumulative sum of duration of contact up to 24h. The full description of the touchable components and the materials they are made of is included in Volume 15 (Biocompatibility). #### Indications for Use 5.6 The Task Force® CORE (TFC) is intended for the measurement of non-invasive continuous blood pressure, pulse rate, and the determination of associated derived hemodynamic parameters. The TFC is intended to be used in professional healthcare facilities and operated by qualified healthcare professional staff. The TFC is intended to be used for adults and under uninterrupted surveillance of the operator. {8}------------------------------------------------ Image /page/8/Picture/1 description: The image shows the logo for CN Systems. The text "cnsystems" is written in a modern sans-serif font, with "cn" in red and "systems" in gray. To the right of the text is a stylized red figure of a woman in a dress, possibly representing fashion or design. The TFC contains software which runs on a separate computer and which is used to operate the device. This software includes a basic frontend (Task Force® CORE Viewer) as well as an interface for integration into other software products. The TFC can provide all signals, as well as measured and derived parameters, to the analog output interface and can acquire signals from the analog input interface. #### 5.7 Comparison of technological characteristics with the predicate device The SD (Task Force® CORE), as well as the PPD (Finapres NOVA) and the SPD (CNAP® Monitor 500 HD) provide a continuous non-invasive blood pressure measurement based on the Pénaz-Principle (vascular unloading), and therefore calculate the patients' blood pressure continuously via an optopneumatic sensor, which is applied to a patient's finger. The Task Force® CORE and the CNAP® Monitor 500 HD utilize the same CNAP® technology and share functionality and sensors, with exception for alarming functionality (according to IEC 60601-1-8) of the CNAP Monitor 500HD, which the Task Force CORE does not have.. While both predicate devices have integrated displays, the Task Force® CORE uses an external (thirdparty manufacturer) application computer. Another technological difference is the fact that the PPD relies on a height correction unit to account for hydrostatic pressure differences occurring due to movements of the finger sensor relative to the heart. On the other hand, the SP (TFC) and the SPD (CNAP® Monitor 500 HD) use algorithms for artifact detection (including movements of the sensor relative to the heart) and warnings and instructions (to recalibrate) in the instructions for use. The present technological differences do not raise questions of safety and effectiveness. For more details on comparison of technological characteristics between the Task Force® CORE and predicate devices, please refer to Volume 12 (Substantial equivalence discussion) of this submission. #### 5.8 Performance data #### 5.8.1 System testing All system verification tests based on system requirements were passed, demonstrating conformance with design and performance specifications. #### 5.8.2 Biocompatibility testing Biocompatibility evaluation was performed according to FDA's guideline "Use of International Standard ISO10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process", dated September 4th 2020 and ISO 10993-1:2018. {9}------------------------------------------------ The Task Force® CORE is intended to contact intact skin on the upper arms and fingers of a patient, for a limited contact duration of up to 24 hours with touchable TFC components (TFC Fingersensor, TFC Forearm Controller Fixing Strap, TFC Armsling, and TFC NBP cuffs). All materials in patient contact of the Task Force® CORE are evaluated to be safe for the intended contact with intact skin and for a limited time. For more information, please refer to Volume 15 (Biocompatibility). #### 5.8.3 Electrical safety and electromagnetic compatibility (EMC) Electrical safety of the Task Force® CORE was demonstrated by type testing according to IEC 60601-1 Edition 3.1 2012 in combination with IEC 80601-2-30: Edition 2.0 2018-03.
