Rotablator™ Rotational Angioplasty System Description The Rotablator Rotational Angioplasty System is a catheter-based angioplasty device utilizing a diamond-coated elliptical burr at the tip of a flexible drive shaft. Tracking coaxially over a guide wire and rotating at up to 190,000 RPM, the burr ablates plaque into fine particles that are disposed of by the body’s reticuloendothelial system. The three main components included in the system are the guide wire, control console system, and the advancer/catheter.

User should take precautions when using the console in conjunction with other medical electrical equipment, as electromagnetic interference between the equipment may affect the performance of the console or other devices. The console complies with IEC 60601-1-2 regulations for radiation of and immunity from electromagnetic energy. The Rotablator Console needs special precautions regarding EMC and needs to be installed and put into service according to the EMC information provided in Appendix D. Portable and mobile RF communications equipment can affect the Rotablator Console.
Description of the Rotablator Console
The Rotablator Console monitors and controls the rotational speed of the burr and provides the operator with performance information throughout the procedure. In the control console, the gas is filtered and then regulated by a fixed-pressure regulator. The resultant pressure is gated by a pilot-actuated valve, and gas flow is automatically adjusted by a proportional pneumatic valve in order to maintain proper Rotablator System operating speed. The gas then enters the gas turbine, and after expanding in the turbine, is exhausted at the bottom of the Rotablator Rotational Angioplasty System advancer. Compressed gas is also supplied to the foot pedal through a triple hose. When the foot pedal is depressed, the gas is returned to the console, where it activates the pilot valve, permitting flow of regulated compressed gas to the Rotablator Rotational Angioplasty System advancer via the front panel turbine connector. With this pilot valve arrangement, the gas flow to the Rotablator Rotational Angioplasty System advancer cannot be throttled by using the foot pedal.
Intended Use The Rotablator Console is intended for use with the Rotablator Rotational Angioplasty System. Refer to guide wire and advancer package inserts for specific information on the use of these components.

Front Panel
Never use oxygen as the propellant for the Rotablator Rotational Angioplasty System. Never connect the regulator to an oxygen cylinder. Oxygen combined with oil or other combustibles in the system can result in an explosion. The use of accessories, transducers and cables other than those specified, with the exception of transducers and cables sold by the manufacturer of the Rotablator System as replacement parts for internal components, may result in increased emissions or decreased immunity of the Rotablator System. The Rotablator System should not be used adjacent to or stacked with other equipment and that if adjacent or stacked use is necessary, the Rotablator System should be observed to verify normal operation in the configuration in which it will be used. This device is not to be used in the presence of flammable anesthetics. If a hissing noise is detected from the console, check to make sure that the pressure of the gas supplied to the air or nitrogen connector does not exceed 758.4 kPa (110 psi). The console is equipped with a pressure relief valve to protect against excessive inlet pressure. Do NOT operate the Rotablator Console with gas pressures in excess of 758.4 kPa (110 psi), as a gas hose may burst. If patient defibrillation becomes necessary, the physician should take the appropriate measures to protect himself against electrocution from the defibrillator. Do not modify or repair. Modification or repair of the instrument by a person other than an authorized Boston Scientific representative may compromise the integrity of the device and/or lead to device failure which, in turn, may result in patient injury or death.

Power Switch: Power is supplied to the console when the switch is in the depressed position. The push button power switch is located in the lower right corner of the front panel. The green light to the left of the switch illuminates to indicate that the power has been turned on. Turbine Pressure Control Knob: The knob located above the power switch is used to adjust the gas pressure to the turbine and consequently, the rotational speed. Turning the knob clockwise increases the turbine pressure (speed) as indicated on the turbine pressure gauge. Counterclockwise rotation decreases the turbine pressure (speed). Turbine Pressure Gauge: Located above the turbine pressure control knob, the pressure gauge displays the pressure of the compressed gas being supplied to the advancer gas turbine. Generally the greater the gas pressure to the gas turbine, the higher the rotational speed. The pressure should not be allowed to exceed 482.6 kPa (70 psi) during normal operation. Flow restrictions have been incorporated into the pneumatic system to prevent the delivery of excessive energy to the advancer. For additional information on operating range, accuracy and precision, see Table 1. Rotational Speed Display (Tachometer): The rotational speed display located in the upper left corner of the console indicates the speed in RPM of the burr and gas turbine. When the gas turbine is not operating, the display is blank. When the foot pedal is depressed, the rotational speed is shown on the rotational speed display. For additional information on operating range, accuracy and precision, see Table 1. STALL Light: The STALL light is located directly below the rotational speed display, and is visible only when illuminated. If the rotational speed of an advancer falls below 15,000 RPM for more than 0.5 second, the red STALL light is illuminated and delivery of compressed gas to the advancer is discontinued. A stall condition may also be detected if the fiber optic connection is not properly engaged. Stall detection is a safety feature designed to discontinue delivery of compressed gas to the advancer in the event of excessive mechanical loading or incorrect connection of the fiber optic. Releasing the foot pedal will clear the stall condition and extinguish the STALL light.

DYNAGLIDE™ Feature Light: The DYNAGLIDE Feature light is located adjacent to the STALL light, and is visible only when illuminated indicating that the Dynaglide Feature is activated. The Dynaglide Feature provides a controlled low speed rotation (approximately 50,000-90,000 RPM) of the Rotablator™ Burr for use during intraprocedure exchange of Rotablator Rotational Angioplasty System advancer or catheter. The Dynaglide Foot Pedal button is used to turn the Dynaglide Feature on or off. Event Timer: Located below the tachometer, the event timer records how long the foot pedal has been continuously depressed with the air turbine and burr spinning. When the foot pedal is released, the timer continues to display the previous event time. Depressing the foot pedal resets and restarts the timer. For additional information on operating range, accuracy and precision, see Table 1. Procedure Timer: The procedure time is the sum of the individual event times and indicates the total time the burr has been spinning during the procedure. For additional information on operating range, accuracy and precision, see Table 1. Table 1

Figure 2 Control Console System To put the Rotablator Console into service, proceed as follows:
Line Cord: This cable plugs into a conventional 100-120 V a.c. or 220-240 V a.c. receptacle (as indicated on the name plate located on the rear of the console) and provides power to the console. In Germany, line cord connections must be to a VDE 0107 compliant installation. The ground wire of the line cord is internally connected to the console chassis. Fuses: The fuses protect the console’s electrical components in the event of a serious electrical fault. If a fuse should fail, refer to Appendix B for replacement instructions. Potential Equalization Connector: Located to the left of the fuse, the potential equalization connector is provided to allow potential equalization between various hospital electrical instruments. In Germany, the potential equalization connections must be made to a VDE 0107 compliant installation. Compressed Gas Inlet: This male connector, located in the top center of the rear panel, mates to the corresponding connector on the supply line from the compressed gas source. Pressure at this inlet should always be between 620.5 and 758.4 kPa (90 and 110 psi) with a minimum flow capacity of 140 l/min (5 standard cubic feet per minute (scfm)). Pressure will be reduced by the console to operating limits. An internal pressure-relief valve protects against input pressures in excess of 792.9 kPa (115 psi) and creates a loud hissing noise in the console when the pressure exceeds 792.9 kPa (115 psi). Dynaglide Foot Pedal Connectors: These two connectors receive the mating pair of connectors from the Dynaglide Foot Pedal. The green hose connects to the right-hand connector and the blue hose to the left-hand connector.
WARNING NEVER use oxygen as the propellant for the Rotablator Rotational Angioplasty System. NEVER connect the regulator to an oxygen cylinder. Oxygen combined with oil or other combustibles in the system can result in an explosion. WARNING This device is not to be used in the presence of flammable anesthetics. 1. Procure a compressed gas cylinder containing either compressed air or nitrogen. In Germany, only compressed air may be used, gas cylinder fittings must be according to DIN 477 Teil 1 (Druckluft), and compressed gas cylinders must be approved by the German government (Bauartzugelassen). A cylinder capacity of at least 2250 l (79.46 standard cubic feet) is recommended, and will provide approximately 20 minutes of service with the Rotablator Rotational Angioplasty System advancer running at full speed. Larger cylinders may be used. A fully charged spare cylinder should always be available. 2. Secure the compressed gas cylinder in accordance with hospital procedures. 3. Obtain a cylinder regulator (relieving type is preferred) capable of delivering at least 140 l/min (5 scfm) at 620.5-758.4 kPa (90-110 psi). Make certain that the cylinder regulator fitting is compatible with the gas cylinder being used. In Germany, only compressed air may be used, gas cylinder fittings must be according to DIN 477 Teil 1 (Druckluft), and compressed gas cylinders must be approved by the German government (Bauartzugelassen).
