"The absence of stent removal is important, but also the patients opinion. In our small survey patients who had experienced both dilatation and stent tended to choose stent. Even our patient who got the first BD stent in 2008, still prefer BD stent all 3-4 months compared to dilatation all 4-6 weeks."

"The auto-expandable, ELLA-CS Biodegradable Stent has been used in our Division since the entry of the device in the market. We found the stent ideal for treating benign strictures, where the risk of stent migration is high with fully covered stents. The stent is also the unique device that can be safely used for treating benign post-surgical strictures of the upper G.I. tract. In case of severe strictures, several BD Stents can be placed without the need for removal, procedure which may be technically difficult and uncomfortable for the patient."

Basic description

BD Stent is a worldwide unique self-expanding biodegradable stent intended for use in the esophagus. 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.

Indications

BD stent is intended for patients over 18 years and is indicated for the treatment of benign esophageal strictures resistant to standard therapy.

Features / Benefits

BD stent 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 PROCEDURE

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 endoscopic and/or fluoroscopic guidance, and for proper positioning, the use of a 0.035″ (0.89 mm) guidewire is recommended.
