The Olympus BF-MP190F is a fully rotatable, ultra-slim bronchoscope featuring an optimal ratio of working channel to outer diameter size, compatible with the radial endobronchial ultrasound (EBUS) probe and an array of sampling devices to expand access to smaller, more distal airways. The BF-MP190F’s ratio of a 1.7 mm working channel to 3.0 mm distal-end outer diameter provides pulmonologists with benefits during access, sampling and diagnosis of lung diseases such as cancer.
