The HV Stent Plus is a fully covered self-expandable esophageal stent with a unique anti-migration design that combines the benefits of partially covered and fully covered esophageal stents. The low migration rate and prevention of tissue ingrowth is complemented by safe and reliable extractability. If the stent is implanted in the distal part of the esophagus and protrudes into the cardia, it may be equipped with an anti-reflux valve that prevents reflux of gastric juices.
The HV Stent Plus is intended for patients aged 18 and older and indicated for palliative treatment of malignant dysphagia, for sealing malignant esophagorespiratory or esophagomediastinal fistula. The device can be temporarily implanted in patients with refractory benign esophageal strictures.
The stent has a minimal migration rate due to its anti-migration design, which is secured by a unique collar at the proximal stent end.
There are metallic retrieval loops with high strength and resistance to acidic environment at both stent ends.
The retrieval loops in combination with centripetally tapering flares allow safe and ergonomic removal of the stent from the esophagus.
The stent has a high radial force for effective dilation of the stricture and resistance to external pressure.
The HV Stent Plus is fully covered by durable silicone, which prevents tumor ingrowth into the stent and allows easy extraction. At the same time, the covering protects the nitinol mesh from contact with stomach acids and potential corrosion.
Platinum-iridium markers located at both ends, in the middle of the stent and on the anti-migration collar ensure visibility of the stent under X-ray.
The stent has atraumatic fully covered flares that reduce esophageal wall irritation and tissue response.
The universal low-profile and flexible 16/22 F delivery system allows easy insertion even into tough stenoses.
If the HV Stent PLUS is implanted in the distal part of the esophagus, it can be equipped with an anti-reflux valve.
MRI compatibility - "MR Conditional", compatible with 1.5 Tesla and 3 Tesla static magnetic field.
The stent is delivered sterile and compressed in the delivery system. We recommend using a 0.035 ”(0.89 mm) / 220 cm ultra-stiff guidewire for the implantation.
