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. | CLEARSIGN II Amplifier Attachment 3, Page 1 {4}------------------------------------------------ {5}------------------------------------------------ Performance Bench testing and in vivo testing were performed to support a determination of substantial equivalence. The CLEARSIGN II Amplifier is Data developed in accordance with 21 CFR 820.30 Quality System Regulation Design Controls. The device was developed and tested in accordance with the following industry standards: . IEC 60601-1, 310 Edition, Medical electrical equipment - Part 1: General requirements for basic safety and essential performance . IEC 60601-1-2 ed3.0 (2007-03).

Testing of specific functions, including the invasive blood pressure function (per IEC 60601-2-34) and the electrocardiographic monitoring function (per IEC 60601-2-27) . Operational temperature and atmospheric environment testing . Testing for compatibility with the CARTO 3D navigation and mapping system (Biosense Webster, Diamond Bar, CA), as LabSystem PRO is labeled for use with CARTO . In vivo animal testing All testing met pre-defined acceptance criteria, thus confirming the safety and effectiveness of each functional aspect of the CLEARSIGN II Amplifier. The results of these tests provide reasonable assurance that the proposed device has been designed and tested to assure conformance to the requirements for its intended use. No new safety or performance issues were raised during the device testing. Conclusion Based on the idential indications for use, substantially equivalent technological characteristics, and safety and performance testing, the CLEARSIGN II Amplifier has been shown to be appropriate for its intended use and is considered to be substantially equivalent to the CLEARSIGN (Borealis) Amplifier as submitted in K050006.
