ABSTRACT:
A device and method for treating collapsed bronchial tubes found in patients with chronic obstructive pulmonary disease and asthma are provided. The device which has a balloon at a distal end delivers energy so that the tissue is indirectly, i.e., conductively, heated by contact with a heated surface of the balloon which has been in turn heated by a heated fluid. The method includes heating the bronchial tube to cause at least a portion of the cross links of the collagen in the wall to unlink/open and subsequently form new cross links after the collagen fibers have realigned. The procedure effectively reinforces the structural integrity of the wall and thereby prevents the lumen from collapsing.
