SKU: 4A-UR-0028

The Percutaneous Nephrostomy (PCN) Drainage Catheter with or without a locking mechanism is a high-performance catheter designed for safe, direct drainage of the renal pelvis. The locking variant uses an internal drawstring to securely lock the distal pigtail loop, preventing accidental displacement, while the non-locking model offers simple, cost-effective placement for short-term diversion.

Key Benefits

  • Secure Distal Lock (Locking Model): Drawstring locking mechanism holds the distal pigtail shape firm inside the calyx, resisting tension forces.
  • Atraumatic Distal Pigtail: Curled pigtail geometry distributes wall contact gently, reducing renal mucosal trauma.
  • High Flow Side Perforations: Strategically arranged drainage holes within the pigtail coil provide uninterrupted fluid evacuation.
  • Radiopaque Polyurethane Material: Provides crisp fluoroscopic visibility for confident positioning.
  • Low Surface Friction: Smooth outer diameter tracks easily over guidewires through tissue layers.
