Invatec, a comprehensive innovator of interventional products, welcomed
the first clinical results of the Drug Eluting Balloon (DEB), IN.PACT
Amphirion, for complex Critical Limb Ischemia (CLI) in Below the Knee
(BtK). As Dr. Andrej Schmidt, leading investigator from the Park
Hospital Leipzig, reported during the LINC congress, preliminary results
indicate a dramatic reduction in restenosis rate by application of the
Drug Eluting Balloon. “In our experience, 69% of Clinical Limb Ischemia
patients with long lesions show restenosis after 3 months. The Drug
Eluting Balloon was able to bring this number down to 31%. Considering
the mean lesion lengths of 17 cm and 58% rate of total occlusions prior
to intervention, these results have the potential to change the way we
treat complex CLI.” Prof. Dr. Dierk Scheinert, chief physician of the
Angiology Department at the Park-Hospital Leipzig and principal
investigator of the IN.PACT Amphirion register, added: “It took us
several years to develop adequate techniques to successfully re-open BtK
arteries but we had no means of preventing restenosis for longer
arterial segments. Drug eluting stents are only feasible in short
lesions. The Drug Eluting Balloon is the first method that brings down
restenosis rates in those complex CLI cases. An interesting observation
is also the nature of the restenosis, if it appears after treatment with
DEB: we see focal segments, not re-narrowing along the total artery.
This makes re-intervention less complex.”
Stefan Widensohler and Andrea Venturelli, co-founders of Invatec,
welcomed the trial results: “This is the first data point on the use of
Drug Eluting Balloons for complex Below the Knee applications, and it is
a very positive data point. We feel encouraged to proceed with our
high-level clinical trial program on DEB which will provide even more
definitive proof that Drug Eluting Balloons can benefit patients with
arterial disease in the coronaries, in hemodialysis shunts and
throughout the entire leg.”
INVATEC has initiated several clinical trials to assess their IN.PACT
DEB line which includes 4 different balloon platforms. Drug Eluting
Balloons have the ability to deliver Paclitaxel to the vessel wall and
inhibit tissue growth within the artery, a factor that leads to the
re-narrowing of arteries. Previous trials conducted on the SFA and
coronary arteries have shown outcomes favoring Drug Eluting Balloons.
