4A Balloon Dilator (Catheter)

SKU: 4A-UR-0050

The Balloon Dilator Catheter is a high-pressure endourological catheter designed for controlled radial dilation of strictures across the urinary tract, including urethral, ureteral, and percutaneous renal access points. By delivering uniform outward pressure without axial sliding, it expands narrow tissue segments with minimal mucosal trauma or bleeding.

Key Benefits

  • Trauma-Free Radial Expansion: Dilates strictly via outward radial force, preventing longitudinal shearing forces on mucosal tissue.
  • High Pressure Tolerances: Rated burst pressures up to 20 ATM allow effective expansion of dense fibrous scar tissue.
  • Non-Compliant Uniform Expansion: Maintains a consistent, predictable cylindrical shape across its length without waist distortion.
  • Radiopaque Shoulder Markers: Gold or platinum radiopaque markers demarcate the balloon boundaries clearly under fluoroscopy.
  • Hydrophilic Coated Shaft: Facilitates smooth tracking over guide wires through narrow or tortuous anatomical passages.
