Tryton side-branch stent launched in Europe

126

A new side-branch stent for the treatment of bifurcation lesions has been launched by Tryton Medical. The Tryton Side Branch Stent System is now available in Austria, Belgium, Denmark, Ireland, Luxembourg, the Netherlands, Norway, Poland, Portugal, Spain, and the United Kingdom. Bifurcation lesions are the largest unmet need confronting interventional cardiology.

“The Tryton Side Branch Stent System offers a unique solution to a persistent problem – how to treat patients with lesions at or near areas of bifurcation in the coronary circulation, a site vulnerable to high rates of restenosis,” said Michael Norell, Department of Cardiology, The Heart and Lung Centre, Wolverhampton, UK. “I have been using the Tryton Side Branch System for more than a year now and have found it to be the ideal solution for these difficult cases. I am excited that the Tryton stent will now be more widely available to physicians and patients in Europe.”    

More than 1,000 patients in Europe have been treated with the Tryton Side Branch Stent System, with more than 500 part of a registry or an investigator-lead clinical trial.

“We are pleased with the positive response from physicians to the Tryton Side Branch Stent System in Europe to date, with more than a thousand patients benefiting from treatment with the Tryton Side Branch System,” said J. Greg Davis, president and CEO of Tryton Medical.  “We are thrilled to widen European availability with this launch, and anticipate commercialising in additional countries in the coming weeks.”

Areas of bifurcation in the vascular system are a common location for plaque and are particularly challenging to treat with currently available stent systems. As a result, the side branch is often left unstented, leaving it vulnerable to higher rates of restenosis, the re-narrowing of the stented vessel following implantation.  Approximately 22% of patients treated for coronary artery disease have diseased bifurcated lesions.


The left main coronary artery is a common location for bifurcation disease. Today, most left main blockages are left unstented or are addressed with bypass surgery. Tryton’s stent has also demonstrated effectiveness in the left main coronary artery.
