The pod bronchial catheter and associated biopsy wire

We have developed a new member of the family of POD catheters which has been found useful for selective examination of the bronchial tree. This flexible magnetic catheter is controlled with external hand held permanent magnets. It has been used to deliver contrast material for selective bronchography and the removal of excess contrast material. The device has application to the recovery of saline washed bacteriological and cytological specimens, for guiding endobronchial biopsy devices to suspected lesions and to selectively deliver medication to disease sites.
