Proudly continuing its legacy of innovation, Medinol presents EluNIR™, the first ever elastomer Drug-Eluting Stent. Combining the clinically proven NIRxcell™ stent platform with a unique elastomer coating and Limus-family drug, EluNIR has demonstrated excellent results in two randomized clinical trials including more than 2,200 patients treated in the United States, Canada, Europe and Israel.

  • We developed eDES™ (elastomer Drug-Eluting Stent) coating in response to concerns over stents coated with durable and biodegradable polymers that are inherently brittle 
  • Drug-Eluting Stents coated with brittle polymers suffer from surface imperfections that can lead to cracking and peeling of the polymer coating. This has been observed directly "out-of-the-box" (crimping deformations), after deployment or drug elution, or during side branch expansion

Cracking and Peeling of "Brittle" Durable and Biodegradable Polymer in Various DES


  • Cracking and peeling of a brittle polymer coating could lead to inflammatory reactions and may contribute to restenosis or thrombosis. Surface imperfections may also result in uneven drug release by under and over-dosing of the vessel wall 
  • The elastomeric coating was designed to eliminate irregularities and deformations in the stent surface and results in a smooth and uniform stent surface that ensures comprehensive and controlled drug elution

  • Unmatched Ease-Of-Delivery -EluNIR owes its deliverability to Flexx², our catheter technology with an innovative spring tip that is more pushable and at the same time more flexible than plastic tips used in other delivery systems
  • Low True Entry-Profile - The spring tip was designed to cross difficult lesions, traverse implanted stents and tackle tortuous and calcified anatomies 
  • The Only Visible Tip – The only DES with a radiopaque tip, enabling visualization of the catheter-tip location during PCI

  • Best In Class Vessel Conformability and Scaffolding – WiZeCell, the clinically proven design of our NIRxcell™ stent minimizes variations in cell size, providing a high conformability in curved sections and uniform scaffolding even during myocardial contractions
  • Low Crossing Profile and excellent flexibility during delivery
  • Optimal side-branch access after stent deployment
  • WiZeCell and eDES coating facilitate uniform release of drug into the vessel wall

                                   WiZeCell Stent Design - Best In Class Conformability and Scaffolding

  • Avoiding Snap Trap Effect - Unlike other stent designs, WiZeCell does not allow large gaps between struts and minimizes the Snap Trap Effect that may lead to tissue prolapse and potentially inflammatory processes and restenosis
  • Medinol’s unique patented manufacturing technology, ensures a more precisely produced stent and markedly-enhanced quality control
  • EluNIR stents are laser-cut from cobalt-chromium alloy panels. The stent panels then undergo Automated Visual Inspection (AVI) on both the luminal and abluminal surfaces and are coated with an elastomer and Limus-family drug
  • QualitySurface is the only technology that currently enables coating stents with an elastomer, providing EluNIR with smooth and uniform surface that ensures comprehensive and controlled drug elution
