Abstract
A new flexible thin needle for transbronchial aspiration biopsy through the flexible fiberoptic bronchoscope was developed. The instrument is described, and the experience gained in 53 human transbronchial punctures is reported. Dignoses of bronchial carcinoma and inflammatory pulmonary disease were made. The needle is a suitable adjunct to other accessories for use with the flexible fiberoptic bronchoscope.
