Safety Information • • • •
Replacement fuses are available through Abbott Medical. The power cord is to be used for disconnection from main power. Make sure any devices that connect to the network interface of the OPTIS Integrated Next comply with the appropriate IEC / national standard and are certified to IEC 60950. Use no electrical peripherals within 6 feet (1.83 m) of a patient unless the peripherals receive power from an isolation transformer that meets medical safety standards.
Note: If the OPTIS Integrated Next is used with peripherals that are powered from a separate wall outlet, the combination is considered to be a Medical System. It is the user’s responsibility to comply with IEC 60601-1 and test the Medical System according to the requirements.
Explosion Hazard WARNING: Do not operate the OPTIS Integrated Next in the presence of flammable anesthetics. Doing so could lead to an explosion.
System Imaging Limitations The OPTIS Integrated Next is intended for use by medical personnel who are knowledgeable in OCT and Physiology procedures. To determine if system use is appropriate, the user must be aware of system imaging limitations. Considerations for Optimal Vessel Imaging The OPTIS Integrated Next can be used to image through vessels or to image the inner surface of certain vessels. Because the Dragonfly Imaging Catheter is smaller than the diameter of the vessel being imaged, the position of the catheter in the vessel has an effect on the portion of the vessel that can be imaged. • Imaging range is greatest when the Imaging Catheter is centered in the lumen. • Imaging range is least when the Imaging Catheter is placed off-center in the lumen, against the wall of the vessel. Considerations for Optimal Tissue Imaging The maximum imaging depth within a vessel wall ranges from approximately 0.9 mm to 1.3 mm and is limited by optical attenuation caused by scattering of the optical beam by microstructures in the vessel. For example, penetration of the OCT beam is deepest in calcified tissue and shallowest in dense fibrotic tissue.

Safety Information
Electromagnetic Interference The system produces images by using digital signal processing techniques that operate in the radio frequency (RF) energy range. The system is therefore susceptible to interference generated by other RF energy sources such as medical devices, information technology products, or radio / television transmission towers. Tracing the source of radiated interference can be difficult. The user must determine if an artifact caused by radiated interference will negatively impact image quality and the subsequent study results. To help identify the source of electromagnetic interference, ask the following questions: • Is the interference intermittent or constant? • Does the interference occur with one catheter only, or with other imaging catheters? • Is the interference present if the system is moved to a different location in the facility? Examples: Placing the system close to an ECG cable can increase electromagnetic interference. Moving the cable or other medical equipment away from the system can reduce electromagnetic interference. Please answer these questions before contacting Abbott Service. The answers will help determine if the problem is in the system or in the imaging environment.
Safety Functions Built Into the OPTIS Integrated Next The following safety functions have been built into the system: • The system disables light output and disables all motors in these situations: – The optical fiber stops rotating due to mechanical failure. – Communication is lost between the imaging engine and the drive motor and optical controller (DOC). – Communication is lost between the computer and the imaging engine. • Pressing the Stop button on the DOC disables power to the DOC and laser output. Refer to “Drive Motor and Optical Controller (DOC)” on page 23.

OPTIS™ Integrated Next Operation and Maintenance Manual – 600233082 Rev. A
System Overview System Features Optical Coherence Tomography (OCT) is an imaging modality that uses fiber-optic technology. The OPTIS™ Integrated Next uses optical imaging catheters that emit near-infrared light to produce high-resolution real-time images. Fractional Flow Reserve (FFR) is the ratio of distal coronary arterial pressure (Pd) to aortic pressure (Pa), measured during hyperemia. It provides the maximal blood flow in the presence of a stenosis as a fraction of the achievable blood flow that would exist in the hypothetical situation that the stenosis was not present. Pd / Pa at rest is the ratio of distal coronary arterial pressure to aortic pressure measured at resting conditions. Resting Full-Cycle Ratio (RFR) is the ratio of Pd to Pa at a point in the cardiac cycle where the Pd / Pa ratio is minimal. RFR is designed to be used at rest and, in contrast to Pd / Pa at rest, is a sub-cycle metric. The physician may use the FFR, Pd / Pa at rest, and RFR parameters, along with knowledge of patient history, medical expertise, and clinical judgment, to determine if therapeutic intervention is indicated. The OPTIS Integrated Next is built into the catheterization laboratory so that OCT and Physiology are immediately available without the need to find, connect, position, and power-on a mobile console. The system allows either the sterile operator or non-sterile operator to control system functions during image and Physiology acquisition and review, and to view the OCT and Physiology images on the main catheterization laboratory monitor boom. In addition, the system incorporates Angio Co-registration, which allows the user to visualize the position of OCT image data on angiography images, tightening the linkage between anatomical assessment with OCT and subsequent therapeutic actions. CAUTION: Medical personnel who use the OPTIS Integrated Next software must be aware of the system’s limitations. Only operators knowledgeable in OCT and physiologic procedures can determine if use of the OPTIS Integrated Next software and OPTIS Integrated Next are appropriate. Be sure to read Safety Information before operating the OPTIS Integrated Next software for the first time. CAUTION: Medical personnel who use the OPTIS Integrated Next must be aware of the system’s limitations. Only medical personnel who are knowledgeable in OCT and physiologic procedures can determine if use of the OPTIS Integrated Next is appropriate.
