Uretral stents are used for temporary internal drainage from the renal pelvis to the bladder. Invumed Innovations provides an extensive range of ureteral stents with different tip configurations, hydrophilic coating and proprietary materials.

Double Loop Ureteral Stents

Product description

Invumed offers wide range short term or long term double loop ureteral stents with mono or multilength, with hydrophilic coating.

  • Invumed uretral stents are made of polyurethane: Tecoflex for the short term and Carbothane for long term use. The products are biocompatible even for long-standing use.
  • Our cross-sectional design feature decreases the liability to compression.
  • All stents are memory free.
  • Colour coding: blue for Tecoflex and white for Carbothane.
  • Hydrophilic coating: available option to improve stent application, decrease incident of associated infection and prolong life of the stent.

Kit Features:

  • Double Loop Stent.
  • Either simple pusher tube (color coded according to the size) with clamp, or coaxial pusher (full application control) for accurate positioning of the stent loop inside renal pelvis or in the bladder.
  • PTFE coated stainless guide wire. Other types of wires are also available as hydrophilic coating, Nitinol wire and zebra wire.
  • Endoscopy Chanel Plug (optional).
