Disposable Dilation Balloon Catheter
🔍 Click to enlarge
Single-use dilation balloon catheter for controlled dilation of strictures in the digestive and respiratory tracts. Non-compliant columnar balloon, 6–35mm capsule diameter, 2–5atm working pressure, transparent body for direct visual confirmation of expansion.
PURETH disposable dilation balloon catheters are used for dilation in narrow areas of the digestive and respiratory tracts — including esophageal, pyloric, intestinal, tracheal, bronchial, biliary and cardiac strictures. The balloon is advanced into the stricture over a guide wire, inflated to its rated working pressure to widen the lumen, then deflated and removed in a single controlled cycle.
The capsule body is made from high-pressure-resistant non-compliant material that maintains its cylindrical shape at the rated pressure without over-expanding or deforming. The transparent, non-deformable body lets the physician clearly observe the expansion effect under fluoroscopy or endoscopy, providing confident, reproducible dilation every time.
Key Features
- Non-compliant design — maintains cylindrical shape and rated diameter at working pressure; no unpredictable ballooning.
- High-pressure-resistant body — engineered material ensures safe, reliable expansion at 2–5 atm.
- Transparent capsule — non-deformable, clear body allows direct visual confirmation of expansion.
- Columnar profile — focused radial force on the stricture, minimal longitudinal stress on adjacent tissue.
- Wide diameter range — 6mm to 35mm capsule diameters covering biliary, esophageal, tracheal and cardiac dilation.
- Multiple conduit lengths — 900 / 1100 / 1800 / 2000mm to match different endoscope working channels.
- Guide-wire compatible — smaller models pass through ≥2.0–2.8mm biopsy channels over 0.032″–0.035″ guide wire.
- Sterile, single use — one patient, one device; no cross-infection, no reprocessing.
FAQ
What is a dilation balloon catheter used for?
It is used for dilation in narrow or strictured areas of the digestive and respiratory tracts — including esophageal, pyloric, intestinal, tracheal, bronchial and biliary strictures. The balloon is advanced into the stricture, inflated to the rated working pressure, then deflated and removed, widening the lumen.
What does non-compliant mean and why does it matter?
Non-compliant means the balloon maintains its cylindrical shape and rated diameter when inflated to its working pressure, without over-expanding or deforming. This delivers controlled, predictable dilation and lets the physician clearly observe the expansion effect through the transparent body — unlike compliant balloons that balloon irregularly at higher pressures.
What capsule diameters and lengths are available?
Capsule diameters range from 6mm to 35mm with capsule lengths of 30–80mm, across five application families (ERCP, percutaneous biliary, esophageal/pyloric/intestinal, tracheal/bronchial, and cardiac). Conduit lengths of 900, 1100, 1800 and 2000mm match different endoscope working channels. Working pressure ranges from 2atm (cardiac models) to 4–5atm (digestive and respiratory models).
Which models pass through standard biopsy channels?
Models with capsule diameter ≤14mm pass through ≥2.8mm biopsy channels over a 0.035″ guide wire. Smaller-diameter models (6–10mm) fit ≥2.0mm channels over a 0.032″ guide wire. Larger models (16–35mm) are designed for percutaneous or direct placement and do not pass through the biopsy channel.
Is the balloon single use, and what documents are available?
Yes, it is a single-use device for one patient only, eliminating cross-infection and reprocessing. PURETH products are manufactured under an ISO 13485 quality management system; export documents, free sale certificates and market certificates (such as CE) are provided or confirmed at the order stage.
