Cook Medical Receives FDA Approval for First 5 mm Diameter SFA Drug-Eluting Stent (Zilver® PTX®)

IN.PACT AV Drug-Coated Balloon Is First and Only to Show Superior and Sustained Results Through Two Years Compared to PTA in Treating Arteriovenous Fistulae Lesions

The data, which were presented virtually as a podium first at the 2021 Charing Cross Symposium, demonstrated that the IN.PACT™ AV drug-coated balloon (DCB) is the first and only DCB to show sustained and superior effectiveness through two years compared to standard percutaneous transluminal angioplasty (PTA) in end-stage renal disease (ESRD) patients with de novo or non-stented restenotic native arteriovenous fistulae (AVF) in the upper extremity.

Zilver® PTX® new 5 mm diameter stent was approved by the FDA. The news was announced today by Cook Medical.  It is the first 5 mm drug-eluting stent in the U.S. with lengths available up to 140 mm that is indicated to treat vessels as small as 4mm in diameter.

The range of Zilver PTX stent diameters now available will address the treatment of vessel sizes from 4–7 mm in diameter.  The new diameter is better sized for smaller anatomy than previous sizes of the stent and provides an additional option to treat patients with lesions in their superficial femoral arteries (SFAs).

“We spend a lot of time listening to physicians to understand their clinical needs. Time and time again, they ask for more treatment options for peripheral artery disease,” said Mark Breedlove, vice president of Cook Medical’s Vascular division. “We’re excited to continue to develop the Zilver PTX line to answer those needs and help more patients around the world.”

The new size is the only 5 mm drug-eluting stent on the U.S. market for peripheral artery disease (PAD) and provides another treatment option for lesions in patients with smaller superficial femoral arteries.

Zilver PTX1 was the U.S.’s first drug-eluting stent used in the treatment of PAD and is the only drug-eluting SFA stent with five-year published data. Zilver PTX has also been shown to cut reinterventions by nearly half through five years, compared to a combination of bare-metal Zilver stents and percutaneous transluminal angioplasty (PTA). 2

Last year, Cook Medical introduced the 140 mm-length stent in both 6 and 7 mm stent diameters and received expanded indications to treat lesions up to 300 mm per patient. Zilver PTX also received an extended shelf life of two years by the FDA.
