The DV Stent Tracheal is a worldwide unique self-expandable tracheal biodegradable stent that degrades in the human body usually 3 to 4 months after the implantation. Therefore, it is an ideal solution for temporary use in benign indications, where it is not necessary to extract it from the body like other non-degradable stents.
Product is available as custom-made device.
DV Stent Tracheal is intended for patients aged 18 and older and is indicated for the treatment of benign tracheal stenoses unless primary surgery is indicated.
The DV Stent Tracheal degrades in the human body usually in 3 to 4 months. This reduces the number of interventions and hospital visits.
The stent is made of polydioxanone, an absorbable material (polymer) used in medicine as a surgical suture for more than 30 years.
Stent integrity and radial force are maintained for 6 to 8 weeks of implantation. Subsequently, the radial force gradually decreases until the degradation of the material after 3 to 4 months.
The pH value affects the stent degradation process. At higher pH, stent degradation is slower, at lower pH, stent degradation is faster.
Low migration is achieved by uncovered stent design.
Polydioxanone is not visible under X-ray, therefore the stent is equipped with gold markers - 1 piece at both stent ends.
MRI compatibility - "MR Conditional", compatible with 1.5 Tesla and 3 Tesla static magnetic field.
The stent is supplied sterile and is packed separately from the delivery system. Just prior to implantation, the stent must be manually compressed into the delivery system. The stent is inserted under bronchoscopic control through a rigid bronchoscope.
