Dynamic Renal
BALLOON-EXPANDABLE COBALT CHROMIUM STENT
Indicated for renal arteries. A stent specifically designed for renal arteries, combining excellent stent and balloon technologies.
KEY FACTS
- Proximal gold marker for superior visibility and accurate stent placement
- Double helix stent design for high flexibility
- Cobalt chromium alloy combining a lower profile with improved radial force
- proBIO coating for improved stent surface biocompatibility1
Product Details
Superior Visibility Enhances Placement Accuracy
A gold plated radiopaque marker ring at the proximal stent end, combined with a cobalt chromium alloy, facilitates superior visibility and accurate ostial stent placement. Furthermore, minimal stent shortening characteristics ensure predictable deployed stent length for additional lesion coverage accuracy.
Increased Stent Flexibility
The double helix stent design ensures high flexibility, homogenous wall coverage and superb conformability.
Lower Crossing Profile and Increased Scaffolding
The cobalt chromium alloy permits thinner struts, which result in a lower crossing profile. Thus, deliverability is improved while the radial force supporting the vessel scaffolding is increased at the same time.
proBIO Silicon Carbide Coating
proBIO acts as a diffusion barrier, sealing the bare metal surface and reducing ion release. In vitro studies have shown up to a 96% reduction of allergenic metal ions2 when the stent surface is coated with silicon carbide. By providing a barrier against ion release, the silicon carbide coating creates a surface that reduces platelet aggregation while facilitating endothelialization.1
Exceptional Delivery Performance
The stent delivery system combines advanced thermal crimping techniques, ensuring secure stent retention forces and a smooth, low crossing profile. The short balloon overhang can prevent barotrauma on healthy vessels and the laser cut, short balloon tip provides excellent crossability and improved trackability.
