Tryton Medical Files Pre-Market Approval Application with US FDA for Tryton Side Branch Stent

Dateline City:

Application is supported by results from the pivotal Tryton Confirmatory Study in the treatment of significant coronary bifurcation lesions.

DURHAM, N.C.–(BUSINESS WIRE)–Tryton Medical, Inc., the leading developer of stents designed to treat
coronary bifurcation lesions, today announced that it has filed the
final module of its Pre-Market Approval (PMA) application with the U.S.
Food and Drug Administration (FDA) for the Tryton Side Branch Stent. If
approved, the Tryton Side Branch Stent would become the first
bifurcation stent available in the U.S.

“Tryton Medical’s differentiated technology addresses the unique
challenges of bifurcated lesions, which affect nearly a third of all
patients treated with angioplasty each year,” said Shawn P. McCarthy,
president and CEO of Tryton Medical. “With today’s PMA filing we are one
step closer to providing an important new option for interventional
cardiologists in the U.S. working to improve the quality of care for
patients suffering from coronary artery disease.”

The application is supported by results from the pivotal Tryton
Confirmatory Study (single-arm clinical trial, n=133) presented
at the 2015 Transcatheter Cardiovascular Therapeutics symposium
which established an acceptable acute safety profile for the treatment
of coronary bifurcation lesions in vessels appropriate for a ≥2.5mm
stent. In addition, a post hoc analysis of the Tryton Randomized
Clinical Trial (n=704) published
in the journal Catheterization and Cardiovascular Interventions

showed the Tryton Side Branch Stent reduced target vessel failure and
improved side branch percent diameter stenosis when compared to
provisional stenting in the intended treatment population (appropriate
for a ≥2.5mm stent).

About Tryton Side Branch Stent

technology to offer a dedicated strategy for treating bifurcation
lesions. Tryton’s cobalt chromium stent is deployed in the side branch
artery using a standard single wire balloon-expandable stent delivery
system. A conventional drug eluting stent is then placed in the main
vessel. Tryton Side Branch Stent has now been used to treat more than
11,000 patients worldwide. The Tryton Side Branch Stent is commercially
available in multiple countries within Europe, Middle East & Africa, is
investigational in the U.S., and is not available in Japan.
