Device Class
Class 2
Intended Use
The CLEARSIGN II Amplifier is intended to amplify and condition electrocardiographic signals of biologic origin and pressure transducer input, transmitting this information to a host computer (the LabSystem PRO EP Recording System) that can record and display the information.
Device Story
CLEARSIGN II Amplifier is a reusable electromedical device used in EP cath labs; operates as a signal acquisition and conditioning unit for the LabSystem PRO EP Recording System. Inputs include intracardiac/surface ECG signals and intravascular pressure transducer data. Device processes these signals and transmits them to the host computer for clinical selection, display, and recording. Used alongside EP catheters, stimulators, and ablation generators. Healthcare providers (physicians/technicians) use the displayed output to monitor cardiac activity and pressure during diagnostic and therapeutic EP procedures; facilitates real-time clinical decision-making during cardiac interventions.
Clinical Evidence
Bench testing and in vivo animal testing were performed. Bench testing included electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), software verification/validation (IEC 62304), drop/ship testing (ISTA 2A), and functional testing for invasive blood pressure (IEC 60601-2-34) and ECG monitoring (IEC 60601-2-27). Compatibility with the CARTO 3D system was also verified. All testing met pre-defined acceptance criteria.
Technological Characteristics
Reusable electromedical signal amplifier/conditioner. Compliance with IEC 60601-1 (3rd Ed), IEC 60601-1-2, IEC 60601-2-34, IEC 60601-2-27, and IEC 62304. Available in 40, 80, 120, and 160-channel configurations. Designed for integration with LabSystem PRO EP Recording System. RoHS compliant.
Indications for Use
Indicated for use during electrophysiology (EP) diagnostic and therapeutic procedures in an EP cath lab to amplify and condition electrocardiographic signals and pressure transducer inputs for recording and display.
Regulatory Classification
Identification
A transducer signal amplifier and conditioner is a device used to provide the excitation energy for the transducer and to amplify or condition the signal emitted by the transducer.

| Device<br>Description | The LabSystem Pro (LS PRO) EP Recording System (K141185) with<br>CLEARSIGN/CLEARSIGN II Amplifier is an integrated system that<br>acquires, displays, records, and measures physiological signals that<br>originate from that heart. The CLEARSIGN II Amplifier is a reusable<br>electromedical device containing hardware and software that acquires,<br>conditions and presents the physiological signal to the LabSystem PRO<br>EP Recording System such that the signals are available for clinical user<br>selection, display and recording. The CLEARSIGN II Amplifier is used in<br>conjunction with the compatible diagnostic electrophysiology (EP)<br>catheters, surface ECG leads, intravascular pressure transducers,<br>intracardiac stimulators, RF ablation generators and cardiac ablation<br>catheters. The CLEARSIGN II Amplifier is intended for use during EP<br>diagnostic and therapeutic procedures in an EP cath lab. |
| Intended Use/<br>Indications for<br>Use | The CLEARSIGN II Amplifier is intended to amplify and condition<br>electrocardiographic signals of biologic origin and pressure transducer<br>input, transmitting this information to a host computer (the LabSystem<br>PRO EP Recording System) that can record and display the information. |
| Comparison of<br>Technological<br>Characteristics | The predicate device for this 510(k) Premarket Notification is the<br>CLEARSIGN (Borealis) Amplifier, K050006 cleared May 27, 2005. The<br>Indications for Use between the predicate, CLEARSIGN Amplifier, and the<br>proposed device, CLEARSIGN II Amplifier, are identical. The<br>CLEARSIGN II Amplifier incorporates fundamentally the same<br>technological characteristics as the predicate device. The basic<br>architecture and design of the hardware and software are the same; the<br>only changes are to bring the equipment to state-of-the-art (specifically,<br>compliance with IEC 60601-1, 3rd Edition), to comply with the EU RoHS<br>Directive, and to implement minor performance improvements. Therefore,<br>the CLEARSIGN II Amplifier is substantially equivalent to the predicate<br>device. |
