Easy and Repeated Access to Peripheral Lung Regions

The diagnosis of peripheral pulmonary lesions has been a challenge over the past decades and the range of diagnostic procedures is wide. Bronchoscopy, with a reported pneumothorax rate of only 1.5%, is the least invasive approach to peripheral lesions 1.

As the world leader in endoscopy, Olympus offers a choice of two bronchoscopic sampling solutions: The combination of a scope and the Guide Sheath or the brand-new ultra-thin BF-MP190F/290F scope.

The New Ultrathin Bronchoscope: BF-MP290F

Supporting Direct Access to the Periphery
The new BF-MP290F ultrathin bronchoscope improves access to deep lung areas, helps approach the lesion, and identifies the lesion when combined with the slim Olympus miniature probe.

Guide Sheath Kit for Accurate Access and Efficient Sampling of Lesions

  • Accessing lung lesions in the periphery remains a challenge with bronchoscopy. The innovative Guide Sheath Kit helps to improve diagnosis of peripheral lung lesions.
  • The guide sheath is advanced and positioned under X-ray or with ultrasonic guidance at the center of a solitary pulmonary nodule.
  • Once positioned at the target site the guide sheath acts like an extended working channel, allowing safe and repeated access to the lesion for taking biopsies and cytology-brushing.

Key Benefits of the GuideSheath System

Less Invasive

Less invasive sampling technique compared to percutaneous or surgical sampling methods.

Multiple Sampling

Multiple sampling and the combination of different sampling methods help to increase yield and diagnostic success.

Reliable and Fast Access

Reliable and fast access to the lesion with less radiation for the patient, and even more precise detection of the center of the lesion is possible with an ultrasonic probe.

Key Benefits of BF-MP290F

Facilitating Access to Peripheral Lung Regions

The cutting-edge slim design, combining fiber optics with a video chip in the handle of the bronchoscope, provides an optimal ratio of outer diameter to working-channel size. With the BF-MP290F bronchoscope, a 3.0 mm distal-end outer diameter is combined with a 1.7 mm working-channel diameter. This scope facilitates access to peripheral lung regions for effective diagnostics.

Advancing Maneuverability

An upward angulation range of 210° supports smoother insertion into the upper lobe bronchi and allows more of a bend in the scope when an EndoTherapy device is inserted into the endoscope’s working channel. The insertion tube can be rotated left or right by up to 120˚ by simply turning a ring on the control section of the scope.

Enhanced Dedicated Sampling Devices

The slim Olympus 1.7 mm ultrasound miniature probe is compatible with the scope’s working channel as well as a cytology brush and biopsy forceps for effective confirmation and sampling in peripheral lung regions.

Olympus Radial Ultrasound Miniature Probes

The BF-MP190F/290F scope and the Guide Sheath are both compatible with the OLYMPUS radial EBUS probe. Studies report that the combination of either the Guide Sheath 2 or of BF-MP190F/290F 3 with the ultrasound probe achieves over 90% lesion identification.


Designed to access even the narrowest lumina, this radial ultrasonic miniature probe with an insertion tube of just 1.4 mm diameter is compatible with the thin 2.0 mm diameter GuideSheath. With an operating frequency of 20 MHz, this probe generates high-resolution 360° ultrasonic images.


This radial ultrasonic miniature probe allows detailed, high-resolution, 360° examination of narrow lumina with an operating frequency of 20 MHz, while being compatible with the 2.6 mm diameter GuideSheath.
