Basic description

DV Stent Bronchial is a worldwide unique self-expanding biodegradable stent intended for use in the bronchial tree. It typically degrades in the human body within 3–4 months after implantation. This property makes it suitable for temporary use in benign indications where subsequent removal is not necessary, unlike stents made of non-degradable materials.

The product is currently available as a custom-made device.

Indication

DV Stent Bronchial is intended for patients over 18 years and is indicated for the treatment of benign bronchial strictures or bronchomalacia. 

Features / Benefits

DV Stent Bronchial typically degrades in the human body within 3–4 months, which reduces the number of medical interventions and hospital visits. The stent is made of polydioxanone, a biodegradable polymer used in medicine for more than 30 years in the form of surgical suture material.  

The integrity and radial force of the stent are maintained for 6–8 weeks after implantation; thereafter, the radial force gradually decreases until the material fully degrades within 3–4 months.

The pH value affects the stent degradation process. In the human body, degradation tends to be slower under neutral pH, but accelerates in acidic pH.

Low migration is ensured by the uncovered stent design.

 

Polydioxanone is not visible under X-ray imaging; therefore, gold radiopaque markers are placed at both ends of the stent. The stent is MRI-compatible (“MR Conditional”) at static magnetic field strengths of 1.5 Tesla and 3 Tesla.

Implantation

The stent is supplied sterile. The package includes a delivery system, compressing tool, and the stent packed in a protective foil. Immediately before implantation, the stent must be manually compressed into the delivery system. The stent is implanted under bronchoscopic and/or fluoroscopic guidance, and for proper positioning, the use of a 0.035″ (0.89 mm) guidewire is recommended.
