Airway Stenosis Dilation Solution

Clinical Pain Points

Conventional single-stage airway dilation balloons present four major clinical shortcomings:
Safety Concerns– The absence of a graded dilation design allows direct high-pressure opening of airway scar tissue, which may lead to airway tearing, massive bleeding, pneumothorax, and pneumomediastinum.
Operational Challenges– Frequent exchanges of multiple instruments during the procedure prolong interventional procedure time, exacerbate airway mucosal irritation, and increase intraoperative coughing and hypoxia.
Logistical and Cost Burdens– Stocking multiple balloon sizes consumes considerable inventory space, increasing overall consumable costs.
High Recurrence Rate– Insufficient release of scar tissue leads to a high rate of airway stenosis recurrence.

Safety Solution– The integrated 3-stage graded balloon enables progressive, stepwise dilation, dispersing airway wall stress and preventing the risks of airway tearing, bleeding, and pneumothorax associated with single high-pressure dilation.
Operational Solution– A single catheter integrates three graduated diameters, allowing graded dilation with a single placement and eliminating the need for frequent instrument exchanges, thereby shortening procedure time and reducing airway irritation, hypoxia, and coughing.
Logistical and Cost Solution– One device covers varying degrees of stenosis, reducing the number of models to stock and lowering both inventory costs and per-procedure consumable expenses.
Long-Term Efficacy Solution – The graded design gently stretches fibrotic scar tissue in layers for more complete release, minimizing tissue recoil and reducing the probability of airway stenosis recurrence.

Minimally Invasive with Low Tissue Trauma– The 3-stage balloon enables progressive, stepwise dilation to reduce tissue tearing, while the soft, atraumatic tip helps prevent mucosal abrasion and perforation.
Precise Positioning– Radiopaque marker bands at both ends of the balloon provide clear visualization under fluoroscopy, allowing rapid identification and accurate positioning at the stricture site.
Comprehensive Size Range– Available in a broad selection of models and sizes to accommodate varying lesion characteristics and patient anatomies.

The Pulmonary 3-Stage Balloon Dilation Catheter is a core minimally invasive device in interventional pulmonology and otolaryngology for airway procedures. A single catheter integrates three graduated dilation diameters, utilizing a progressive, controlled radial expansion technique to replace multiple single-size balloons and repeated exchanges. It delivers irreplaceable clinical value across multiple dimensions—safety in treating airway stenosis, procedural efficiency, indication coverage, patient outcomes, and departmental operations—making it the first-line standard-of-care device for benign central airway stenosis.
