EluNIR DES in a Challenging Case - Case Study

Background:

This paper describes a challenging case of implantation of the EluNIR™ Ridaforolimus eluting elastomeric stent (Medinol Ltd.). This complex case involved a patient with a flow-limiting lesion in a native coronary artery post bypass surgery.

The new EluNIR stent system includes a stent with a low metal footprint that comprises struts of variable width: ultra-narrow struts having a width of 40µm and narrow supportive struts having a width of 72µm. The combination of different strut widths enables the stent to provide both excellent flexibility and conformability, and at the same time adequate radial strength to support the artery after dilation. The stent geometry enables excellent deliverability even in tortuous and calcified lesions. In addition, the delivery system of EluNIR includes an innovative metallic spring tip that was designed to enhance crossability and buckle resistance. Other stent delivery systems that typically have polymer tips, are prone to flare-out and buckle and may impact deliverability.
