4A Filiform Dilator

SKU: 4A-UR-0014

The Filiform Dilator (with accompanying follower catheter) is a specialized urological dilating instrument designed to navigate complex, tortuous, or pinpoint urethral strictures that resist standard catheterization. The initial ultra-thin, highly flexible filiform tip leads through the stricture, after which a larger follower dilator is threaded onto its base to safely dilate the tract.

Key Benefits

  • Navigates Severe Strictures: Extremely fine, pliable tip safely bypasses strictures, false passages, and prostatic obstructions.
  • Screw-Lock Coupling: Interlocking threaded male/female fittings allow secure attachment of follower catheters without risk of intraurethral detachment.
  • Atraumatic Flexibility: Flexible distal filiform conforms smoothly to stricture contours without puncturing mucosal tissue.
  • Gradual Stricture Dilation: Follower dilators progressively expand narrow urethral segments over the safe guide path of the lead filiform.
  • Drainage Capability: Hollow followers allow immediate urine evacuation once past the obstruction point.
