HALYARD* Mini-BAL Sampling Catheter is a telescoping catheter that safely samples a patient’s lower respiratory tract secretions, giving physicians the data they need to make an accurate lung infection diagnosis and prescribe targeted antibiotic treatment.

Using bronchoalveolar lavage as a tool to help diagnose lower respiratory tract disease has been shown to reduce both antibiotic usage and healthcare costs.

Since 2001, over 200,000 HALYARD* Mini-BAL Sampling Catheters have been produced, showing a history of safe use.

The HALYARD* Mini-BAL Sampling Catheter has a soft, directional tip that allows safe and quick retrieval of lower respiratory tract samples. This can help avoid the false negatives and false positives seen in an estimated 23% of endotracheal aspirate cultures.
These secretions from the distal airway can help identify infectious pathogens of the lung for a microbiologically confirmed diagnosis.

Features and benefits include:

  • Procedure can be performed bedside in minutes by trained respiratory therapist or other trained clinicians
  • Directional tip allows right or left lung sampling
  • Maintains PEEP when used with supplied ventilator adapter
  • Features a soft, cushioned, radiopaque tip for safe sampling from the lower lung
