Biodegradable Stent

The Biodegradable stent (BD) is a unique device designed to treat benign strictures in the mid & lower oesophagus and helps to facilitate long term stricture remodelling. BD helps to eliminate complications commonly associated with migration and re-intervention in benign disease.

It's about pathway remodelling...

Indicated for peptic, caustic & anastomotic benign strictures in the mid and lower oesophagus, BD is designed to minimise the need for re-interventions and streamline the patient pathway. The BD Biodegradable Stent provides a cost effective, patient focussed alternative to high-frequency oesophageal dilatation.

Benefits

Improves patient quality of life
Minimises requirement for repeat hospital visits
Using the BD stent ‘would appear to offer patients with benign disease greater than 50% possibility of long-term symptom resolution’¹
Indicated for peptic, anastomotic and caustic strictures
Lower migration rates, when compared to plastic or metal stent placement for benign strictures²
Eliminates potential complications associated with SEMS migration when stenting for benign disease

Product Features

Biodegradable (BD) Stent

Polydioxanone (PDS) material fully degrades approximately 12 to 13 weeks after insertion (pH dependent). Highly visible radiopaque markers located centrally and at each end of the stent
Radial force is maintained for approximately 6-8 weeks helping to facilitate long term stricture remodelling
Degradation process involves partial bioabsorbption of PDS material and natural passage through the digestive tract
The stent is manually loaded onto the delivery system immediately prior to implant
Easy-to-use distal release pull-back delivery system with detachable splittable olive
