The aim of the study is, primarily, evaluate the safety of the use of the silicone stent HCPA-1 in patients with clinically significant tracheal and/or bronchial stenosis. Secondarily, this study aims to evaluate the efficacy of the use of the silicone stent HCPA-1 who are in the same conditions described above and also estimate the costs the use of these silicone stents involve.
* It is a prospective multicenter clinical study, not controlled, with evaluation of clinical variables before and after the intervention (insertion of one or more silicone stents in the trachea or bronchi and main or intermediate bronchus by rigid bronchoscopy under general anesthesia). * 110 patients, both genders, will be followed for one year, total of 8 visits, in order to evaluate the safety of the procedure of stent insertion. It is allowed to include patients for whom it is indicated the combination of treatments (eg, electrocoagulation followed by stent placement) - full anticoagulation or severe disturbance of coagulation. (Includes: use of any anticoagulant, by oral, intravenous or subcutaneous administration with full intention of coagulation / therapy; coagulopathy with INR\> 2.0 or aPTT \[KTTP\]\> 1.5 times control or platelet count \<50000). Note: The use of antiplatelet drugs (aspirin, clopidogrel, ticlopidine) is allowed. \- The HCPA-1 silicone stent is made of biocompatible silicone, medical grade, via injection process in the matrix using different densities of the same material for a set of prostheses with rigid and flexible variables; available in the following dimensions (diameter x length in mm): 9x30, 9x50, 11x30, 11x50, 13x30, 13x50, 14x30, 14x50, 16x50, 16x70, 18x50 and 18x70. Requires specific surgical (applicator) for insertion.

RECRUITINGNumber of participants with adverse events as a measurement of Safety
three main adverse events will be followed: * migration of the stent; * granuloma formation; * accumulation of secretion
Time frame: 1 year
Improvement in Dyspnea using a Dyspnea score as a measurement of Efficacy
MMRC dyspnea score will be used to measure the improvement of the patient's respiratory condition
Time frame: 1 year
