Maestro 4000 Controller The Maestro 4000 Controller is an RF Generator specifically designed for cardiac ablation. It produces userselectable power-controlled or temperature-controlled RF power output in the range of 0 to 150 watts into a nominal tissue impedance of 100 ohms. It delivers RF power via a monopolar method driving current between a single active electrode at the tip of the ablation catheter and one or two dispersive pads applied on the skin. When used with BSC open-irrigated catheters, the RF Generator communicates with the MetriQ Pump to coordinate delivery of RF energy with irrigation flow to the catheter tip. Note: Throughout this manual, the term RF Generator, or Generator, refers to the Maestro 4000 Controller.
Maestro 4000 Pod The Pod, which is connected to the RF Generator, allows connection to all BSC catheters and provides connections for dispersive pad(s) to complete the RF circuit. The Pod also connects to EP recording systems and provides RF filtering to allow continuous electrogram recording during RF delivery. The Pod model varies by operating territory and determines the maximum power setting allowed by the RF Generator. Maestro 4000 Remote Control The optional Remote allows the user to control the RF Generator with up to 75 feet between the user interface and the sterile field. Maestro Foot Switch The optional Foot Switch provides hands-free control to start/stop RF delivery. Dispersive Pads A Dispersive Pad provides external patient contact to complete the RF circuit. It disperses current over a large area to minimize damage due to heating of skin and underlying tissue. It is also known as the DIP (dispersive indifferent pad), ground pad, or return pad.

OPERATION •
• • •
WARNING: Pacemakers, implantable cardioverter/defibrillators, and leads can be adversely affected by radiofrequency energy. It is important to refer to the manufacturer’s instruction for use prior to performing ablation procedures. WARNING: The impedance display of the RF Generator should be continuously monitored during RF power delivery. If a sudden rise in impedance is noted, RF power delivery should be discontinued. WARNING: Failure of the RF Generator could result in an unintended increase of output power. WARNING: The risk of igniting flammable gases or other materials is inherent in the application of RF power and precautions must be taken accordingly. Some materials, for example cotton, wool and gauze, when saturated with oxygen may be ignited by sparks produced in normal use of the HF surgical equipment. Note: Boston Scientific relies on the physician to determine, assess and communicate to the individual patient all foreseeable risks of the cardiac ablation procedure.
Start-Up Turn the RF Generator ON by toggling the Mains Power Switch on the front panel to the “I” position. If a Remote is connected to the RF Generator: • Turn the Remote ON by toggling its Mains Power Switch to the “I” position. • Press the Generator Remote button to activate the Remote Control Panel. The RF Generator and Remote (if applicable) will initiate a self-test. • “SELF TEST” appears on the alphanumeric display, a continuous audio tone is generated for approximately two seconds, and all front panel displays/indicators are lit. • The Pod and a Catheter must be connected to complete the self-test. • If no System malfunction is detected, the RF Control Button will flash to indicate the RF Generator has entered STANDBY state. • If a System malfunction is detected, the RF Generator or Remote (if applicable) will not operate. The red SYSTEM FAULT indicator will be lit. The displays for Power, Temp, Impedance and Time will all read 888. Standby State STANDBY state initiates automatically after System start-up and whenever Deliver state is terminated. Power, Temperature, Impedance, and Time settings may be viewed and adjusted in this state. When STANDBY state is initiated after System start-up: • The default settings shown in Table 2 will appear in the Power, Temperature, Impedance, and Time displays. Table 2.

This section provides basic operation instructions for the Maestro 4000™ Cardiac Ablation System.
Select RF Delivery Settings Use one of the methods below to select RF Delivery settings for a procedure. • Recall RF Delivery settings stored with the Memory Buttons. • Manually set the RF Delivery settings as described below. Control-Mode Selection • WARNING: With non-irrigated catheters, start with a low temperature setting in temperature-control mode, and then slowly titrate the temperature setting up to achieve the desired effect. With irrigated catheters, select power-control mode with a temperature setting intended to ensure that adequate fluid is irrigating the tip of the catheter. The mode of operation can be toggled between Power-Control Mode and Temperature-Control Mode by pressing the Control Mode Button while the unit is in STANDBY mode (The control mode button is inactive during RF power delivery). The control-mode selection determines the effect of the Power and Temperature settings. • In Power-Control Mode: • The amount of RF power delivered will equal the power setting unless the measured temperature exceeds the temperature setting. • The temperature setting is a limit for catheter tip temperature. If the limit is exceeded, power will be reduced or halted to lower the measured temperature below this limit. Note: When power is reduced or halted, an operational message or diagnostic code will appear in the front panel display. See OPERATIONAL MESSAGES Section, or DIAGNOSTIC MESSAGES Section for additional information.

•
In Temperature-Control Mode: • The power setting is a limit. The RF Generator is allowed to adjust RF power delivery up to this limit to achieve the target temperature. • The temperature setting is the target temperature. Note: The target temperature may not be reached if the power setting (limit) is reached.
The default control modes for BSC Catheters are listed in Table 3. When a catheter is initially connected, the RF Generator automatically switches to the default control mode for that catheter. However, the user may switch control modes by pressing the control-mode button.

Power Setting • WARNING: To minimize the potential for thrombus formation, inadvertent damage to cardiac tissues, and collateral damage to adjacent tissue not intended for ablation, begin by using a low power setting and gradually increase the power output if necessary, especially in areas where low blood flow and correspondingly low convective cooling may be present. Temperature Setting • WARNING: To minimize the potential for thrombus formation, inadvertent damage to cardiac tissues, and collateral damage to adjacent tissue not intended for ablation, begin by using a low temperature setting and gradually increase the power output if necessary, especially in areas where high blood flow and correspondingly high convective cooling may be present. • WARNING: The displayed temperature is not the maximum tissue temperature. The measured temperature may be influenced by the degree of tissue contact and variations in blood flow. The difference between the max tissue temperature and the displayed temperature increases when using irrigated catheters, and the correlation with lesion formation is greatly reduced. The temperature displayed with irrigated catheters is not intended to guide lesion formation. The temperature displayed with irrigated catheters is intended to verify that the tip is being sufficiently irrigated. This behavior will minimize the potential for thrombus formation and/or inadvertent damage to nearby tissue. Impedance Setting The impedance upper limit may be adjusted between 150 Ω to 300 Ω.
Selecting Average and Maximum Display Press the “Maximum” and/or “Average” Buttons, if those values are to be displayed. RF Power Delivery with Open-Irrigated BSC Catheters Use of the RF Generator with BSC open-irrigated catheters requires proper set-up and preparation of the MetriQ™ Pump and the MetriQ Irrigation Tubing Set. The MetriQ Pump Operator’s Manual provides complete instructions for set-up and operation of the MetriQ Pump and MetriQ Irrigation Tubing Set . Starting RF Power Delivery: • Press the RF Power Control button once, or hold down the Foot Switch pedal. • The MetriQ Pump will switch from standby flow to ablation flow. • Delivery of RF Power will start when the Pre-RF Delay is complete. • The RF Power Control button will illuminate and remain lit until RF power delivery stops. • RF Power will stop automatically when the setting for maximum duration of RF Power Delivery is reached. • The Pump will switch to standby flow when the Post-RF Delay is complete. Stopping RF Power Delivery: • To stop delivery of RF Power before reaching the setting for maximum duration, press the RF Power Control Button, or release the Foot Switch pedal. • The RF Power Control button will flash to indicate the RF Generator is in STANDBY state. • The Pump will switch to standby flow when the Post-RF Delay is complete.
