CLINICAL VALIDATION

Bronchoscopic Transparenchymal Nodule Access (BTPNA) 1

  • Biopsy yield was 100% for procedures where a tunnelled pathway (tract) was created (10 out of 10)
  • Overall yield for BTPNA was 83% (10 out of 12), the tract could not be created in two patients (both having lesions in left upper lobe)
  • No occurence of pneumothorax, localized hemorrhage, or bronchial or pulmonary lacerations

LungPoint Virtual Bronchoscopic

    • LungPoint has the highest published yield compared to other navigation systems in published META Analysis (80%)2
    • Studies show image guided navigation improves ability to find correct airway and localize target3
