简要总结
The goal of the trial is to establish a method, material, and patient-specific stent design that will last longer, fit better, and cause less trauma to the airway and the patient.
详细描述
This is a prospective trial of the clinical utility of a patient-specific silicone stent implant for patients with complex airway disease, requiring an airway stent. The aim of this study is to observe the outcomes associated with the implants. Current stents have been suboptimal for treating benign stenosis of the airway and we are seeking to create a better treatment option. We hypothesize, based on the previous compassionate-use cases, that placing a patient-specific silicone stent will effectively alleviate symptoms associated with stenosis of the airway. The main measure of effectiveness will be patient-reported outcomes.
The implant will occur on Day 0 and TDI and formal assessment for AEs will occur on Day 1.
Patients will be seen on Day 60 +/- 14 days for formal assessment including TDI and QOL, dynamic CT, and a bronchoscopy procedure will be performed as per our usual standard of care. Additional ascertainments of the TDI and QOL measurements will occur at 90 and 180 days after implantation.
A standardized assessment of the stent as well and any modification or any other treatments will be recorded. Washing for cultures will also be done per standard of care during any bronchoscopy.

入选标准
- •Patients will be considered for study inclusion if they have a clinical need for airway stenting defined by prior evidence of existing stents that have at least temporarily improved symptoms, but now suffer from stent complications; or those for whom a stent would be offered if an appropriate size and shape was available. Subjects must meet the following inclusion/
排除标准
- •to be eligible for the study.
- •Understand and voluntarily sign an informed consent form.
- •Patients must be at least 22 years of age
- •Patients must be able to undergo routine non-contrast CT scans of the chest
- •Patient must be stable for general anesthesia and have an airway amenable to rigid bronchoscopy and stent implantation.
- •The patients must have at least an expected 6 month survival.
- •Patient must be able to maintain standard of care follow-up schedule and have access to standard of care medications and nebulizer machines and/or suction and oxygen as required for primary disease management.
- •Patient must be able to personally provide consent and be able to describe Dyspnea and QOL and other patient-reported outcomes (PROs) required by study design
- •Patient must require a stent that is within the design envelope of the patient-specific stents, as defined by COS (See Section 5.4 of this protocol for envelope)
- •Exclusion Criteria: Patients may be excluded if management of the airway problem can be safely and effectively treated with commercially available stents (SOC), non-stenting techniques, or surgical options.
- •Patients may be excluded if the disease can be managed by simply removing prior stents or performing more conservative therapies.
- •Chronic anticoagulant therapy that could limit the safety of performing rigid therapeutic bronchoscopy in a timely manner. (I.e. Plavix within one year of drug eluding cardiac stent (DES) or 6 weeks following bare metal coronary stent)
- •Unstable cardiac disease
- •Allergy to silicone
- •Stenting to manage vascular compression syndromes.
- •Multi-drug resistant bacterial or fungal chronic infections
- •Emergent/urgent clinically indicated stent.
- •Chronic/permanent mechanical ventilation.
- •Pure Excessive Dynamic Airway Collapse (EDAC) patients.
- •Pure Pulmonary Resistance (Rp) patients.
