Vet Stent-Trachea®
Vet Stent-Trachea® is the world’s only tracheal stent optimized for veterinary applications. It is a self-expanding Nitinol stent that can easily be repositioned during placement. Based on feedback from thousands of clinical cases and countless hours of laboratory research, the next generation stent is now available. This stent features the proprietary and exclusive PurLux® high definition stent surface which improves the fatigue characteristics of the stent and enhances its biocompatibility resulting in less local inflammation. The stent is loaded on Infiniti’s Ergo Linear™ delivery system that ensures that every delivery system comes out of the box without any curves.
Duality Vet Stent®
Duality Vet Stent® is a new addition to the Vet Stent-Trachea® line and represents the culmination of years of work to better understand the mechanics of tracheal collapse. It is intended to address cases where the diameter of the trachea varies. The Duality Vet Stent® is a variable diameter stent that will closely match the tracheal diameter at all points, something that a standard stent cannot do. These stents are up to 400% stronger when placed in a variable diameter environment and the durability has been improved by about an order of magnitude. The Duality Vet Stent® also has the PurLux® high definition surface that improves stent durability and decreases the local inflammatory response.
There is a tracheal stent patent pending.
