Product Description

Details / Features

Structure

  • Different magnitudes of segmental radial force may reduce reactive hyperplasia
  • Full silicone covered to prevent tissue in-growth
  • Four(4) anti-migration anchors at the distal end prevent the risk of migration
  • Retrieval string facilitates easy removal of stent
  • Efficient radial force
  • High flexibility
  • Atraumatic ends
  • Thermo-reactive radial force

Pre-Loaded Delivery System

  • Outer sheath: Metal braided tube contributes excellent push-ability and track-ability
  • Radiopaque ring at outer sheath: Shows deploying progression
  • Yellow marker: Cystoscopic marker to place stent at orifice border
  • Inner stent: Reinforces overall radial force
  • Three(3) Radiopaque markers : Fluoroscopic markers for accurate placement. Accordance with stent loaded portion – Proximal, Center and Distal

Indications:

Benign and Malignant Urethral Obstruction
