4A Step Dilator

SKU: 4A-UR-0049

The Step Dilator is a specialized endourological dilating instrument featuring distinct step-up diameter increments along a single shaft. Used for controlled dilation of urethral strictures or percutaneous nephrostomy tracts, it allows clinicians to feel tactile click transitions as each larger diameter segment crosses the targeted obstruction.

Key Benefits

  • Tactile Step Transition: Distinct physical steps along the shaft provide clear tactile feedback as each incremental size engages the stricture.
  • Controlled Radial Expansion: Reduces abrupt tissue tearing by combining gradual step transitions with short dilating zones.
  • Single-Instrument Efficiency: Replaces the need to open multiple individual dilators, saving time and inventory costs.
  • High Columnar Pushability: Rigid core prevents shaft bowing during axial force application.
  • Radiopaque Step Markers: Clearly visible under fluoroscopy for accurate depth control relative to anatomical landmarks.
