Ultravet Medical Devices is currently hard at work developing a new innovative bifurcating bronchial stent.
Collapse can occur in a discrete location, or multi-focal, and may be an extension of tracheal collapse.
Treatment for most cases of bronchial collapse consist of a combination of medical therapy including cough suppressants, antibiotics, bronchodilators, anti-inflammatory medications (e.g. corticosteroids), and sedatives.
Indications for bronchial stenting would be the inability for medical therapy to adequately control the clinical signs. Typical candidates for stenting have discrete collapse in one or two bronchi with normal appearing airways throughout the rest of the bronchial tree. Patients with chronic bronchitis and multifocal collapse or diffuse chondromalacia are usually not good candidates for the procedure.
Diagnosis of bronchial collapse is made via bronchoscopy. In addition, samples can be taken for cytology and culture and biopsies taken if nodules are present.
The initial workup for bronchial stenting includes:
Here is an image of our bifurcating bronchial stent prototype. Development on this device continues.
