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.
