STENTYS’ Self-Apposing Stent Featured in New Article Published by the Journal of the American College of Cardiology

STENTYS highlighted as a solution to minimize stent malapposition in clinical practice

Regulatory News:

STENTYS (Paris:STNT) (FR0010949404 — STNT), a medical technology company commercializing the world’s first and only Self-Apposing® Stent for treating acute myocardial infarction (AMI), today announced that the Journal of the American College of Cardiology (JACC) published a “State-of-the-Art Paper” entitled “Mechanisms, Pathophysiology, and Clinical Aspects of Incomplete Stent Apposition,” which highlights STENTYS’ Self-Apposing Stent among novel devices to minimize stent malapposition, also known as incomplete stent apposition (ISA), in clinical practice.

According to the authors: “Some particular clinical scenarios such as acute coronary syndromes, bifurcations, tapered vessels, overlapping stents, and chronic total occlusions might predispose to ISA. Interventional cardiologists should be committed to optimal stent choices and techniques of implantation and use intravascular imaging guidance when appropriate to aim at minimizing acute ISA.”

The authors advise that novel devices, such as STENTYS’ Self-Apposing stent, which already demonstrated an early reduction of ISA compared with balloon-expandable stents during primary PCI, can reduce malapposition and the potentially harmful consequences with which it is associated.

Gonzague Issenmann, co-founder and Chief Executive Officer of STENTYS said: “Malapposition continues to be a challenge for cardiologists, particularly when vessel diameter is ambiguous or fluctuating, as in the post-infarction phase. We are pleased that JACC and the authors provided such a detailed discussion of this issue and its dreadful consequences for patients, and that our Self-Apposing Stent technology was highlighted as a solution to malapposition.”

About the STENTYS Self-Apposing® StentThe STENTYS Self-Apposing® Stent addresses the stent-sizing dilemma that cardiologists are confronted with when treating heart attack patients or patients with atypical artery anatomy. Its flexible, self expanding design takes the shape of the patient’s unique vessel anatomy and apposes to the irregular contours of a blood vessel, in particular after an AMI as the vessel dilates and the clot dissolves. It reduces the risk of malapposition and complications associated with conventional stents in this setting. The STENTYS Self-Apposing Stent has been marketed in Europe since receiving CE Mark in 2010. The STENTYS Sirolimus-eluting stent should receive the CE Mark during the second half of 2014.

About STENTYSSTENTYS is developing and commercializing innovative solutions for the treatment of patients with acute myocardial infarction (AMI, or heart attack) and complex coronary artery disease. STENTYS’ Self-Apposing® Stents are designed to adapt to vessels with ambiguous or fluctuating diameters, particularly in the post-infarction phase, in order to prevent the malapposition problems associated with conventional stents. In the APPOSITION III clinical trial, STENTYS stents demonstrated a very low one year mortality rate among 1,000 high-risk AMI patients when compared to recent studies with conventional stents.
