EluNIR First-In-Patient Implantation

Dr. Alaide Chieffo, MD; Dr. Francesco Giannini, MD

The first implantation of the EluNIR elastomeric drug-eluting stent. A complex case involving a flow-limiting lesion in a native coronary artery post an extremely tortuous LIMA bypass.

EluNIR DES in a Challenging Case

Antonio Colombo, MD, Francesco Giannini, MD; Columbus Clinic Center, Milan, Italy

A challenging case of implantation of two EluNIR elastomeric drug-eluting stents in a highly calcified and tortuous lesion post bypass surgery.

Deliverability

  • Purposefully designed spring tip for superior deliverability in challenging anatomies
  • Enhanced pushability and flexibility
  • The tapered spring tip was designed to closely track the guidewire and eliminate flare-out and buckling common to plastic tips
  • The only radiopaque tip, enabling visualization of the catheter-tip location during procedure
  • Reinforced hypotube for better hub-to-tip force transfer, enabling to navigate through tortuous anatomy without kinking

Designed for superior deliverability and crossability

Excellent Flexibility & Pushability – Flexible spring tip, designed to eliminate flare-out and buckling. Low true-entry-profile

Tip Visibility – The only radiopaque tip

Superior Crossability – of difficult lesions, calcifications and implanted stents

Spring Tip demonstrates best-in-class combination of Pushability and Conformability

Stent Design

  • Low footprint cobalt-chromium design with ultra-narrow 40µm struts
  • Best In Class Scaffolding: adaptive cell size designed for optimal scaffolding and uniform drug dosing while preventing tissue prolapse
  • Excellent conformability in curved sections even during myocardial contractions
  • low crossing profile and flexibility for improved deliverability
  • Optimized side branch access

Low footprint variable width design

40µm ultra narrow struts provides flexibility and conformability

Optimal scaffolding area provides uniform support and drug elution and prevents tissue prolapse

72µm struts provides excellent radial strength

Natural vessel curvature and myocardial contractions test the limits of stent design and scaffolding integrity.
EluNIR’s optimized cell size ensures uniform scaffolding and prevents tissue prolapse and strut overlap.

Note how other stents enable large openings, contributing to tissue prolapse and potentially restenosis.

 

eDES Coating

  • The first and only elastomeric* Drug Eluting Stent (eDES™)
  • exceptional surface quality
  • long term coating integrity
  • Comprehensive and controlled drug elution

*Elastomer – high elasticity polymer

  • Medinol purposefully designed EluNIR’s coating for high performance and endurance.
  • EluNIR’s elastomeric coating maintains long-term surface integrity and enables predictable, uniform release of a limus drug to the vessel wall.
  • Improved surface quality and long term coating integrity may promote clinical advantages such as more uniform drug elution, better endothelialization, lower inflammation, lower ST and restenosis rates.

After Elution

  • Polymer coatings of other drug eluting stents often present surface deformations, webbing, cracking and peeling
  • These surface imperfections were associated with inflammation and thrombogenicity and may also result in non-uniform drug release1
