What are the advantages of Millar Mikro-Tip® catheters over conventional fluid-filled systems?
Higher Frequency Response Fluid-filled systems typically have a useful frequency range of less than 20 Hz because they have a very low resonant frequency. The frequency response of Millar Mikro-Tip catheters is flat to 10 kHz. Position Independence In conventional fluid-filled systems a long column of fluid (water) separates the source of the pressure within the body from a sensing element outside the body. Due to this configuration, any change or disturbance in the position of the sensing element relative to the water column will cause an inaccurate pressure reading. By measuring pressure through a sensor placed directly at the source, Mikro-Tip catheters are not affected by such external factors. Motion Artifact Mikro-Tip catheters virtually eliminate motion artifact. Because Mikro-Tip catheters measure pressure directly at the source, they minimize artifact (unwanted noise) caused by the beating of the heart (catheter whip), patient movement, motion of the catheter inside the body,
